I. INTRODUCTION
This document covers scientific highlights and personnel changes for the period 1 October - 31 December
1995. Highlights emphasize concluded projects rather than work in progress. The March 1996 NOAO Newsletter Number 45 contains information on major projects, new instrumentation, and operations. The appendices to this report summarize telescope usage statistics and observational programs.
II. SCIENTIFIC HIGHLIGHTS
A. Cerro Tololo Inter-American Observatory 1. The Faintest Known White Dwarf
The white dwarf luminosity function incorporates information on the age and star formation history of the Galactic disk which is independent of other techniques. In particular, the least luminous white dwarfs set lower limits on the disk age, and thus the age of the Universe. The faintest known white dwarfs have Mv ~ 16.2. Age estimates for these stars are in the range 6.5-11 Gyr, with the variation largely due to uncertainty in the core composition. The white dwarf luminosity function declines abruptly at this absolute magnitude, and this decline has been interpreted as being due to the age of the Galactic disk. The question remains, do even less luminous and older white dwarfs—however rare—exist? The search for very low luminosity white dwarfs is still very active.
A concerted effort has been carried out for a number of years by Maria Teresa Ruiz and her colleagues at
Cerro Calan Observatory (U. of Chile). Selection of promising candidates is done with a classic technique, blinking plate pairs from the ESO Schmidt telescope to identify faint stars with substantial proper motion.
The magnitude limit is about mR ~ 21 and motions as small as 0.1 arcsec yr"1 are detectable with a few years' time base. Followup observations at CTIO and other facilities in Chile help winnow the most interesting objects out of the hundreds found on a plate pair.
One such object is the cold DC type white dwarf ESO 439-26. Following its initial discovery in 1988, preliminary spectroscopic and astrometric data suggested it to be of very low luminosity. Several years' subsequent investigation at CTIO have now established this definitively. This result is based on another classic technique, the determination of trigonometric parallax, applied with modern CCD detectors in a program led by Claudio Anguita (U. of Chile). Observations were carried out on the CTIO 1.5-m telescope over a five-year period, using initially a 312 x 508 RCA CCD and more recently a Tek IK device. With 0.3 arcsec pixels and seeing at 1.2 arcsec or better, 40 frames yield a parallax of 0.024± 0.003 arcsec, or Mv = 17.4—more than one magnitude fainter than the faintest previously known white dwarfs. The existence of such an extreme low-luminosity white dwarf may imply a very large value for the age of the local Galactic disk.
Alternatively, the low luminosity of ESO 439-26 could be accounted for if it is a massive white dwarf with a correspondingly small radius—also a rare beast, but not one implying great age. Only a detailed comparison of the observed absolute flux distribution with theoretical models can resolve the ambiguity. Ruiz and
Anguita, together with S. K. Leggett (IRTF) and P. Bergeron (U. of Montreal), haveused BVRI photometry obtained on the CTIO 1.5-m and 0.9-m telescopes and model atmosphere calculations by Bergeron and colleagues to make this comparison. They find the high mass interpretation to be the correct one, independent of details of atmospheric composition. The best fit to the photometiy gives Teff=4560 K, log
g = 9.0, and M = 1.2 M solar masses—twice that of a typical white dwarf. Comparison with carbon core evolutionary models yields an upper age limit of 6.4 Gyr for the best fit solution. More complex interiors models would tend to reduce the age significantly, but are not yet available at appropriately cool temperatures.
Infrared JHK photometry, in progress, will help constrain the atmospheric composition. Interestingly, spectroscopy does not. Even though Ha can be detected in low mass white dwarfs of comparable effective temperature, the large surface gravity of this small, massive object collisionally broadens hydrogen lines to the level of undetectability. Although not of great age, the high mass of ESO 439-26 makes it unique in one respect. Comparison with model isochrones indicate it is in an advanced state of crystallization. 2. Evidence for a Black Hole in the X-ray Nova GRO J1655-40 X-ray novae are binary systems in which a compact object accretes gas from a companion star. The observed velocity of the secondary starcan be used to determine the minimum mass of the compact object. In six cases to date, the mass function of the compact object has been found to exceed 3 solar masses,
confirming the presence of black holes in these systems. These black hole X-ray novae (or BHXNs) provide a unique opportunity to study black holes, since one can observe both the secondary starvia the absorption lines and the accretion disk surrounding the black hole via the emission lines.
The unusual X-ray nova GRO J1655-40 is the newest and one of the most interesting of the BHXNs. Following its discovery in August 1994 by the Compton Gamma-Ray Observatory, Charles Bailyn (Yale U.) and collaborators located the optical counterpart using the CTIO 0.9-m telescope. Soon after, superluminal radio jets were discovered by Tingay et al. (1995, Nature, 374, 141) and Hjellming et al. (1995, Nature, 375, 464), making GRO J1655-40 the only galactic superluminal source which can be observed optically. The jet ejection, at 92% of the speed of light, appears to be episodic and asymmetric, and is so rapid that distinct motions can be seen from one hour to the next.
Bailyn and collaborators returned to CTIO in 1995 to make further optical photometric and spectroscopic measurements of GRO J1655-40. Photometry was obtained on 18-25 March and 5-24 April with the 0.9-m telescope and CCD imager, and on 28 March to 2 April with the CTIO 1.5-m telescope and CCD imager. In addition, spectra were obtained with the RC spectrograph on the CTIO 4-m telescope on the nights of 30 April and 2-4 May. As the photometric data were obtained, it became clear that the light curve showed eclipses and was periodic on a timescale of approximately three days. The overall light curve shape was found to consist of a broad triangular primary minimum, and a shorter secondary minimum displaced by about 0.5 in phase from the primary minimum. By analogy with the eclipsing X-ray binary CAL87, it seems likely that an eclipse of a large accretion disk by the secondary star is responsible for the primary minimum, and an eclipse of the secondary star by the disk explains the secondary minimum.
The spectra of GRO J1655-40 obtained by Bailyn et al. had less prominent Balmer emission lines and stronger high-excitation lines than X-ray novae in quiescence, presumably because the outburst was still
underway. Nevertheless, it became immediately apparent from the individual spectra that a stellar F-type absorption spectrum was present. Cross-correlating the spectra against an F5 subgiant of known radial velocity revealed sinusoidal radial velocity variations with a period of 2.6 days and a semi-amplitude of 227
km s"1. These parameters yield a minimum possible mass of the compact object of 3.16 ±0.15 solar masses. The maximum stable mass of a neutron star is 3 solar masses for all possible equations of state, and below 2.5 solar masses for most plausible equations of state. Thus, in the absence of exotic matter and/or
non-Einsteinian gravity, a mass function above 3 solarmasses requires the compact object in GRO J1655-40 to be a black hole.
The eclipsing geometry of GRO J1655-40 allows the possibility of using eclipse mapping techniques to explore the geometry of the system in further detail. Changes in the flux and spectral line shape during eclipse can be used to map the inner regions of the accretion disk. Hence, a multiwavelength campaign involving GRO, ROSAT, ASCA, XTE, and a variety of ground-based optical and radio observations (including 0.9-m time at CTIO) was organized for March 1996. One of the primary goals of this campaign was to use the eclipses to map the high-energy, optical, and radio emission. When successful, these observations allow the emission geometry near an accreting, jet-producing black hole to be explored in unprecendented detail.
3. The Stellar Metallicity Distribution in Omega Centauri Suntzeff (CTIO) and Kraft (UCO/Lick) have finished a project on stellar abundances and radial velocities for giant stars in the Galactic globular cluster co Centauri based on the Call infrared triplet. Two samples of stars were observed: 234 stars at Mv ~+ 1.25 on the lower giant branch at radial distances between 8' and 23', and 145 stars at Mv — 1.3 at radial distances between 3' and 22'. They found 199 and 144 radial velocity members, respectively, in the two samples. These samples were corrected for evolutionary effects to provide an unbiased distribution of the underlying stellar metallicity. They found a mean cluster velocity
of = 234.7±1.3 and a velocity dispersion of a0bs=ll-3 km s"1 for the bright sample, and = 232.9±1.2, Gobs = 10.6 km s"1 for the faint sample. The statistical errors of the dispersions are less than 1 kms"1.
Previous metallicity studies found a non-gaussian metallicity distribution containing a tail of metal-rich stars. Suntzeff and Kraft have confirmed these results except that the unbiased cluster metallicity distributions were found to be significantly narrower. The abundance distributions contain the following key features: (1) No very metal-poor stars, (2) a sudden rise in the metal-poor distribution to a modal [Fe/H] value of -1.70 consistent with a homogeneous metallicity unresolved at the 0.07 dex level, (3) a tail to higher metallicities with more stars than predicted by simple chemical evolution models, and (4) a weak correlation between metallicity and radius such that the most metal-rich stars are concentrated to the cluster core. The unresolved metal-weak tail implies that the gas out of which co Cen formed was well-mixed up to the modal metallicity of the cluster. Therefore, co Cen like other Galactic globular clusters, seems to have formed in a pre-enriched and homogenized (up to the modal metallicity) environment. The existence of a weak metallicity gradient supports the idea that co Cen self-enriched, with the enriched gas sinking to the cluster center due to gas dissipation processes. Suntzeffand Kraft also note, however, that the metal-rich stars are more massive than the bulk of the stars in the cluster, and could also have sunk to the
center by dynamical mass segregation over the lifetime of the cluster.
B. Kitt Peak National Observatory 1. Infrared Colors and Pre-Main-Sequence Evolution
The picture of star formation from core ignition until arrival on the main sequence is gradually taking shape as more sophisticated theory is confronted with increasingly informative observations. The general picture envisions several stages in the pre-main-sequence phase. The star may begin life while heavily enshrouded in dust during a period of maximum mass accretion and ejection. As the shroud is cleared away, the system shows strong excess emission in the ultraviolet and in emission lines from the accretion disk and associated materials, along with a continuing infrared excess from hot dust. The stage
immediately preceding the main sequence shows a decreased infrared emission and the fading of the material producing the thermal disk and emission lines.
A substantial multi-wavelength survey reported by S.J. Kenyon and L. Hartmann (Smithsonian Astrophysical Obs.) in the November 1995, Astrophysical Journal Supplements confirms the general picture of pre-main-sequence evolution. They combined observations of the Taurus-Auriga molecular cloud region from several telescopes, including the IRAS satellite, and the KPNO 1.3-m with the near-IR
photometer, Imager, and SQITD four-color imager. More than half the stars in the region show excess near-IR emission, and that emission correlates with other measures of activity, such as atomic hydrogen emission, ultraviolet excess, millimeter continuum emission, reflection nebulae and molecular outflows.
The fraction of the total energy of a pre-main-sequence star emitted in the far infrared shows a smoothly decreasing progression from the most heavily embedded stars to the bluest accretion-disk objects with high rates of mass flow. Since the ER colors are consistent with an Mailing dusty envelope model, the amount of envelope emission must decrease as the star develops.
A gap in the mid-infrared diagram of stellar colors suggests that there is an abrupt transition from the phase of strong accretion mass flow producing a thick accretion disk to that of weaker flow with a thin disk. The distribution of inferred disk energy distributions is consistent with flared disks rather than
geometrically flat ones. The Hertzsprung Russell Diagram and the derived luminosity function in the near-infrared 1.0 \x.m and 2.2 |^m bands indicate that the molecular cloud complex has formed stars steadily over the past 1 to 2 million years. A comparison of the prediction of theoretical evolutionary tracks with the observed locations of objects in the near-infrared color-magnitude diagram allow inferences about the initial mass function (IMF). That relative distribution of masses is more like an
empirically constructed IMF for the solar neighborhood by Miller and Scalo than a pure power-law in mass formulated by Salpeter. There seems to be little evidence for evolution in the total luminous output of sources as they move from dust-enshrouded to exposed high accretion rate objects. The last finding contradicts theoretical expectations, and enforces the concept of progress in understanding. 2. Bargain Redshifts for Faint Galaxies
Deep images of the sky present large numbers of very faint galaxies, which hold the key to defining the evolutionary history of each modern galaxy type. Even the largest telescopes cannot obtain detailed
spectra of the faintest objects, and very large amounts of time must be committed to redshift surveys to trace large-scale structures at substantial redshifts. These difficulties have continually motivated astronomers to find a way to determine redshifts from the much lower resolution measurement of spectral energy distributions provided by broad-band photometry. A recent mathematical exploration of a promising technique was described in the December 1995, Astronomical Journal by A. Connolly, I. Csabai, and A. Szalay (Johns Hopkins U.), D. Koo (UCSC), R. Kron (Fermilab), and J. Munn (U. Chicago). They had measured a large sample of galaxies from their photographic survey taken over years on the Kitt Peak Mayall 4-meter telescope. Plates had been taken in ultraviolet (U), blue (Bj), red (RF), and near-infrared (IN). The first question is the amount of independent information contained in the fluxes recorded in the different colors, and how that information can be correlated with spectroscopically measured redshifts. They used a measure of that information, the fractal
dimensionality, to show that galaxies occupy roughly a two-dimensional planar surface in fourdimensional color space, that slowly twists with increasing redshift. The position of a galaxy within that space is determined by its redshift, luminosity and spectral type.
The authors then devised combinations of the brightness measurements through the color filters, essentially rotating the coordinate frame to better align with this surface of galaxy measurements. They were able to define a set of four orthogonal coordinates: the first correlates with redshift, the second with flux, the third with spectral energy distribution, and the fourth is normal to the "plane" of galaxies. The existence of a data plane is consistent with yet a third type of analysis, principal component analysis, which reveals the variables that contain most of the correlated power. The first component contains 98% of the power, the second 2%, and the third 0.04%. When the principal component directions in multi color space are compared to the orthogonal components derived to maximize the dependence on single physical variables, the agreement was found to be very good. The first component corresponded to flux, the second correlated most strongly with redshift, and the third with spectral energy distribution shape.
With this mathematical construction in place, it was possible to test the accuracy with which redshifts could be determined from a slightly curved (quadratic) representation of the data surface in galaxy multicolor space. The authors found that they could estimate redshifts to an accuracy of 0.05 for blue magnitudes brighter than 22.5 from the combined color measurements alone. Experiments with exclusion of various passbands confirmed that the blanketing break that produces the depression of the spectral
energy distribution at wavelengths shorter than 4000A provides most of the power in the redshift determination.
The authors then used model spectral energy distributions and simulated counts with lower measurement uncertainties than those provided by the photographic data to suggest that the redshift uncertainty could be decreased to as low as 0.02. The ultimate limit is the "warping" of the data plane as the weak-featured near-ultraviolet energy distribution occupies more of the optical passband at higher redshifts. With the assumption of no evolution, that limit occurs at z ~ 0.8. The combination of that effect and galaxy color evolution will provide the ultimate limits to the technique until evolutionary sequences are very well defined. For lower redshift systems, the technique is powerful in assigning redshifts for large, faint samples of galaxies.
3. Weighing the Dwarf Spheroidal Companions to the Milky Way The puzzle of Dark Matter has long been manifest in the dwarf spheroidal galaxies in the Local Group. Early measurements of the velocities of a few stars in each galaxy suggested that there was a considerable unseen mass producing the apparent velocity dispersion. The results remained open to question because of three concerns: were the uncertainties quoted for the velocities of individual stars reliable? Did the velocities reflect a large contribution from the orbital motion of binary stars? Were dynamical conditions in the galaxies appropriate for the application of the virial theorem of energy equilibrium as a valid means for deriving total gravitational mass? The advent of multifiber spectroscopy enabled a new global attack on the velocity dispersion problem. T.E. Armandroff (KPNO), E.W. Olszewski (U. of Arizona), and C. Pryor (Rutgers U.) report in the November 1995, Astronomical Journal on their measurements of individual stellar velocities in the Draco and Ursa Minor Dwarf Spheroidal galaxies. They used the Hydra multifiber positioner and bench
spectrograph on the KPNO Mayall 4-meter telescope to measure velocities in 762 stellar spectra of 94 stars in Ursa Minor, 91 stars in Draco and many foreground objects. They took extreme care in calibration and in error simulation to determine the median uncertainty in individual velocity
measurements of 4 km/s. The stability of the Hydra - bench spectrograph combination was clearly demonstrated in the year-to-year repeatability of the measurements. Binary stars were straightforwardly identified in the repeated measurements. The authors were also able to obtain detailed comparisons with systematics of previously published velocities of other groups.
Armandroff et al. found that the distribution of velocity members of the Ursa Minor and Draco dwarf spheroidals was not as modeled by a simple isothermal distribution. They found that about two times
more stars were found outside the ellipses predicted to contain 90% of the population than predicted by the model. A possible explanation is that the radius at which the Milky Way truncates the population of the satellite galaxy, the tidal radius, has been calculated to be too small, and that the stellar distribution is telling us more about the dynamics of the tidal encounter.
The original stellar velocity probes were chosen to be Carbon Stars, because of the strong velocity signal from their sharp carbon absorption bands. The new velocity survey allowed discovery of additional members of this population and allowed an inference about their nature. Since the bulk of the Carbon
Stars in Ursa Minor and Draco are significantly less luminous than stars at the tip of the red giant branch in the Hertzsprung-Russell diagram, they cannot be the products of dredging up carbon in intermediatemass single-stars. They must be the result of the transfer of material in binaries.
The major finding is that of the dynamics of the galaxies. Ursa Minor shows a slow rotation of about 3 km/s, while Draco shows no evidence of rotation. The velocity dispersion in Ursa Minor is 10.4 ± 0.9
km/s, while that of Draco is 10.7 ± 0.9 km/s. If extreme velocity objects are excluded, the values drop to 8.8 ± 0.8 and 8.5 ± 0.7 km/s, respectively. Simple dynamical models predict corresponding mass to light ratios between about 60 and 90. These are the largest values for any measured dwarf spheroidals, and are much larger than those found for any star cluster or the old stellar population of any luminous galaxy. The result confirms and provides strengthened evidence for the presence of dark matter as providing much of the gravitational potential of these dwarf spheroidal systems. Further work on the spatial distribution of the dark matter will provide another step toward unraveling its enigmatic role in galaxy formation.
C. National Solar Observatory 1. Fine Dark Threads and the Temperature of the Solar Corona
L. November (NSO) and S. Koutchmy (Institute of Astrophysics, Paris, France) have identified very fine "dark and bright threads" in the solar corona from high spatial resolution, white-light coronal observations obtained during the eclipse of 11 July 1991, using the 3.6-meter Canada-France-Hawaii Telescope on Mauna Kea in Hawaii. These are the highest resolution observations of the solar corona
ever made because of the unique opportunity of observing the totally eclipsed Sun with a large-aperture telescope. After dividing out the average radial variation from the white-light photographic observations, relatively dark and bright fine threads can be identified. Spatial filtering reveals clearly the thread-like loop structures, which are as small as 1 arcsec or 720 km. The main feature is an "arcade" of concentric
dark and bright threads which extends above a small prominence just above the solar limb. The threads appear to be unchanging, though the time series is too short to get a good determination of their lifetimes.
The relative electron density depletion required to explain the observed dark-thread contrast, assuming that they are isolated, cylindrically symmetric structures, is found to be 100%, which indicates that the
fine dark threads are fully evacuated. Only an unphysically large temperature enhancement could produce the degree of evacuation that is measured in the dark threads, and a temperature one half the ambient is required to produce the density enhancements seen in the bright threads. But the scale-height temperature in the bright threads is found to be within 15% of the ambient. On the other hand, pressure fluctuations necessary to produce the measured density fluctuations are produced by an approximately 1-gauss non-force-free magnetic field. Such a picture is consistent, as the threads appear to follow the 6
magnetic field. Dark and bright threads appear to have a preferential organization, probably lying on current sheets that separate normal potential magnetic regions, which is consistent with a widely-held theoretical model for the solar coronal magnetic field.
The most significant aspect of the discovery of dark threads may be that steady non-force-free magnetic fields can play a direct role in defining the coronal temperature structure. If evacuated threads exist within a few arcseconds of the solar surface, then forces that constrain their expansion radially would
also impose a constant pressure region and a corresponding sharp radial density drop at the level where the magnetic energy density in the threads becomes comparable to the surrounding gas pressure, effectively acting to "hold down" the whole surrounding solar atmosphere. Such a sharp radial density drop would produce, according to thermodynamic arguments, a corresponding temperature discontinuity which can lead to a very hot corona. This is an attractive possibility, as it avoids the difficulties encountered in traditional models that have been generally unsuccessful in providing the necessary direct heating to explain the 1-5 million degree coronal temperature.
2. An Objective Test of Magnetic Shear as a Flare Predictor D. Neidig (PL/GPSS, stationed at NSO/Sac Peak), in collaboration with J.B. Smith and members of the NASA Marshall Space Flight Center magnetograph group, completed a preliminary study of magnetic shear as a flare predictor. The study was based on a statistical analysis and classification of 57 activeregion-days, using Multivariate Discriminant Analysis (MVDA) as an objective means of deriving relationships between preflare variables and flare outcomes. A total of 51 preflare variables, including 23 based on shear (defined as the angular deviation of the active region magnetic field from a potential field) were used in the analysis. Classifications of flare outcomes were derived both with and without incorporation of variables based on shear. It was found that variables based on shear and on the strength of the transverse magnetic field, while they were able to classify tomorrow's flare outcomes as well as or better than conventional region indices or variables based on longitudinal fields, did not produce improved classification scores when used in combination with the remaining variables. As in previous studies using MVDA, past and present flare activity, i.e., persistence, was found to be the most significant variable in classifying tomorrow's flare activity. Further, when persistence was used in addition to other variables, absolutely no reduction in classification scores was observed when the shear variables were removed. These somewhat surprising results should be considered as preliminary, as the sample was relatively small and did not include large (X-class) flares. Further studies, using a larger sample and including large flares, are under consideration. The results of this study were presented at the Sixteenth NSO/Sac Peak International Workshop, "Solar Drivers of Interplanetary and Terrestrial Disturbances."
3. Solar Particle Dynamics
Two major mysteries of the Sun involve the dynamics of the upper solar atmosphere. The solar wind, a particle flow with a speed of 400-1000 km/sec, is accelerated somewhere in the solar atmosphere by a process that remains unobserved. Solar flares, events that have direct terrestrial consequences, involve reconfigurations of the magnetic fields of the solar atmosphere; and yet direct measurements of the magnetic field changes in solar flares have not been made. New observations in the near-infrared spectrum of the Sun aim to address these mysteries. Several important absorption lines are now being observed in the 1000-2000 nm region of the solar spectrum, and new information about solar physics is being squeezed from the data.
Daily observations of the solar disk in the Helium I absorption line at 1083 nm at the NSO/KP Vacuum Telescope provide the only ground-based measurement of coronal holes. The 1083-nm line is formed
after photo-ionized helium recombines with free electrons, and in a coronal hole there is less X-ray radiation to ionize helium atoms, and thus less 1083-nm absorption. The daily 1083-nm maps show the position and extent of coronal holes on the Sun, and when combined with solar wind observations, prove that the fast streams of the solar wind originate in coronal holes. New observations from the NSO/KP
Vacuum Telescope by M. Penn and H. Jones (Goddard Space Flight Center, stationed at NSO) have also shown that the 1083-nm line widths in coronal holes differ from the surrounding quiet-Sun regions. The narrower line widths they observe in the coronal holes may reflect a thermal difference or may be caused by a change in velocities of gas flow.
The magnetic field in the solar atmosphere can be probed by measuring the polarization of the 1083-nm helium line. Observations by Penn and Kuhn at the NSO/SP Vacuum Tower Telescope measured magnetic fields in the hot emission kernels of a small flare in 1993. These data illustrated the events in
the later stages of the flare, but lacked the valuable pre-flare observations that a dedicated instrument can obtain. For this purpose, a new video-rate filtergraph/magnetograph, using the 1083-nm line, is almost on-line at the NSO/KP Vacuum Telescope. Jones, Harvey and Penn are now working on this instrument,
which will measure the 1083-nm polarization in solar active regions in a systematic way, obtaining important pre-flare measurements for all events. The exploitation of the 1083-nm polarization by this instrument will be a valuable tool in the study of solar flares during the next solar activity cycle beginning around 1997.
D. US Gemini Program The US Gemini Program is a division of NOAO which serves as a liaison between the US community and the international Gemini Project. Personnel in this office include Todd Boroson, the US Gemini
Project Scientist, Kathy Wood, Technical Administrator, and Mark Trueblood, Project Engineer. Efforts began this quarter to hire another astronomer into the USGP to assist with the development and implementation of operations and instrumentation activities.
This quarter saw the completion of the first Gemini mirror blank at the Corning plant in Canton, New York. The blank was delivered on schedule and has been transported to Reosc Optique in France for polishing. The hexagonal segments for the second blank are complete and will be fused in early 1996. Excavation and concrete work has proceeded on schedule at both north and south Gemini sites. The
USGP collaborated with IGP personnel in the placement of a video camera, mounted on a railing of the nearby Canada-France-Hawaii Telescope, that continuously views the Gemini construction on Mauna Kea. Images from this camera are transmitted back to Tucson and can be viewed on the World-Wide Web at the Gemini website.
The USGP organized and carried out a successful Gemini workshop at the VHI Latin American Regional Astronomy Meeting in Montevideo, Uruguay. This was done in collaboration with the national Gemini Project offices of the South American Gemini partners, Argentina, Brazil, and Chile. In addition to general participation in the meeting by the USGP staff, some IGP personnel, and some US members of the Gemini Board, a two-hour session on Gemini was presented to the 300 Latin American astronomers at the meeting. This session comprised three short presentations on different aspects of the Gemini program followed by a lively question and answer session.
During this quarter, the USGP devised a procurement plan for the Gemini Mid-IR Imager. The procurement will involve two competitive selections, the first to produce a concept, and the second to complete the design and fabricate the instrument. This two-stage approach is motivated by the limited funding available initially and by the desire to facilitate participation by a number of instrument groups. The announcement of opportunity for the first competition was released at the end of the quarter.

Days off from work
Compared to last year, NOAO experienced a decrease in the number of injuries/illnesses, from 14 to 8. At the same time there was an increase in illnesses, from 1 to 2, and a slight increase in the average lost workdays, from 5.8 to 6.9 per person.
The types of injuries/illnesses broke down as follows:
Sprain/strains Slips/falls Repetitive motion/cumulative trauma
4 2 2
KPNO and NSO/SP Mountainwide Fire Alarm Systems:
The installation of individual fire alarm systems begun in CY 1994 was completed. Except for the houses
at NSO/SP which are protected with stand-alone smoke detectors every major building or complex is equipped with a fire alarm system. Each system includes the appropriate smoke and heat detectors, manual pull stations, audio/visual alarms and transmitter which transmits the trouble or alarm signal to a central station receiver and annunciation system.
NSO/SP Sewage Treatment Plant was upgraded and permitted with the State of New Mexico.
NSO/SP Visitor Center - Environmental Impact: Required National Environmental Protection Act approvals were obtained for the future visitor center site.
Tucson Headquarters Fire Alarm System was upgraded with a new digital transmitter for transmitting fire alarm signals over dedicated phone lines to the central station and monitoring the phone lines. Mandatory Department of Labor/BLS Statistics Survey for 1994 occupational injuries/illnesses for the Tucson and KPNO sites were prepared and sent to the Arizona Industrial Commission. Loss Prevention Surveys/Reviews:
Various surveys/reviews were conducted and the resultant recommendations furnished in regards to the following:
KPNO mountain brush fire danger Fire prevention - KPNO facilities
Survey of optics polishing compounds for potentially dangerous levels of radioactivity General survey of Tucson facilities and all work stations in Block 5, bounded by First and Second Streets and Martin and Warren Avenues
Removal of 4-m shutter drive system
Safety procedures, equipment and ventilation system for the HF-HC1 acid etching of CTIO 4-m secondary mirror
Twenty PC workstations to assure ergonomically sound principles WIYN Safety Program Fire safety of KPNO facilities
Extra-low frequency electromagnetic fields for high levels and the potential for causing PC monitor flicker
2.1-m ring change with focus on adequacy of personal fall protection Potential displacement of 02 by N2 and/or He2in KPNO IR Labs Working alone in KPNO IR lab and optics basement
Final review of 16" Visitor's Telescope facility 4-m telescope shutdown with focus on adequacy of personal fall protection Orbital Debris Liquid Mirror Telescope Training:
Several KPNO and NSO/SP EMT's received refresher training and were recertified.
Two KPNO staff members received 160 hours of emergency medical training and certified as EMTs.
The NSO/SP Safety Officer attended the state of New Mexico's conference on the requirements for underground storage tank.
The KPNO and NOAO Safety Officers attended the Southwest Safety Congress, including various seminars.
Four KPNO staff members completed 40 hours of First Responder Training. GONG field support staff were trained in first aid and CPR.
The NOAO Safety Officer attended ITT Hartford's loss control management course.
KPNO Maintenance operations attended a demo with hands on use of personal fall protection equipment. KPNO and Tucson maintenance operations staff received refresher training on the use of fire extinguishers.
