1.0 OBSERVATIONS SCHEDULED AND ACCOMPLISHED:

    1.1 Completed Four Sets of STIS/CCD 9088 (Next Generation Spectral 
Library of Stars)

        The Space Telescope Imaging Spectrograph (CCD) was used to produce 
a "Next Generation'' Spectral Library of 600 stars for use in modeling the 
integrated light of galaxies and clusters by using the low dispersion UV 
and optical gratings of STIS.  The library will be roughly equally divided 
among four metallicities, very low {Fe/H < -1.5}, low {-1.5 < Fe/H < -0.5}, 
near-solar {-0.5 < Fe/H < 0.1}, and super-solar {Fe/H > 0.1}, well-sampling 
the entire HR-diagram in each bin.  Such a library will surpass all extant 
compilations and have lasting archival value, well into the Next Generation 
Space Telescope era.  No problems occurred.

    1.2 Completed Seven Sets of WF/PC-2 9318 (POMS Test Proposal: WFII 
Parallel Archive Proposal Continuation)

        The WF/PC-2 was used to perform the generic target version of the 
WFPC2 Archival Pure Parallel program.  The program was used to take 
parallel images of random areas of the sky, following the recommendations 
of the Parallels Working Group.  There were no reported problems.

    1.3 Completed Four Sets of STIS/CCD 8901 (Dark Monitor-Part 1)

        The Space Telescope Imaging Spectrograph (CCD) was used to monitor 
the darks.  There was no anomalous activity.

    1.4 Completed Four Sets of WF/PC-2 8942 (Cycle 10 Intflat Sweeps and 
Linearity Test)

        The WF/PC-2 was used to monitor the pixel-to-pixel flatfield 
response and provide a linearity check.  These intflat sequences are done 
once during the year and the images will provide a backup database in the 
event of complete failure of the visflat lamp as well as allow monitoring 
of the gain ratios.  There were no reported problems.

    1.5 Completed Five Sets of WF/PC-2 8937 (Cycle 9 Supplemental Darks pt2/3)

        The WF/PC-2 was used obtain three dark frames every day to provide 
data for monitoring and characterizing the evolution of hot pixels.  No 
problems were encountered.

    1.6 Completed STIS/CCD 8291 (The Alpha-Element/Iron Ratio in Starburst 
Populations)

        The Space Telescope Imaging Spectrograph (CCD) was used to observe 
A and F supergiants in NGC1569, the closest starburst galaxy.  Spectra 
around 6200 Angstrom taken with the G750M grating will be used to determine 
element abundances of Fe and several Alpha-elements.  The galaxy has 
experienced a strong starburst over the past few hundred Myr and possibly 
only very few and much less intense episodes of star formation at earlier 
epochs.  Chemical evolution models predict a significant Alpha/Fe 
enhancement in the galaxy.  The proposal completed with no reported anomalies.

    1.7 Completed WF/PC-2 8059 (POMS Test Proposal: Targeted Parallel 
Archive Proposal)

        The WF/PC-2 was used to observe the parallel opportunities 
available in the neighborhood of bright galaxies are treated in a slightly 
different way from the normal pure parallels.  Local Group galaxies offer 
the opportunity for a closer look at young stellar 
populations.  Narrow-band images in F656N can be used both to identify 
young stars via their emission lines, and to map the gas distribution in 
star-forming regions.  The observations completed nominally.

    1.8 Completed WF/PC-2 8939 (Cycle 10 Internal Monitor)

        The WF/PC-2 was used to calibrate the internal monitor, to be run 
weekly to monitor the health of the cameras.  No problems were encountered.

    1.9 Completed Four Sets of WF/PC-2 8935 (Cycle 10 Standard Darks)

        The WF/PC-2 was used to obtain dark frames every week in order to 
provide data for the ongoing calibration of the CCD dark current rate, and 
to monitor and characterize the evolution of hot pixels.  Over an extended 
period these data will also provide a monitor of radiation damage to the 
CCDs.  The proposal completed with no reported problems.

    1.10 Completed STIS/CCD/MA1 8638 (Temperature Scale And Metal 
Abundances Of Hot Hydrogen-Rich Central Stars Of Planetary Nebulae)

        The Space Telescope Imaging Spectrograph (CCD and MA1) was used to 
perform UV spectroscopy on a sample of hot hydrogen-rich central stars of 
PNe, covering the hottest phase of post-AGB evolution. The spectra will 
then be analyzed with fully metal line blanketed NLTE model atmospheres in 
order to determine T_eff, surface gravity, and chemical composition.  The 
proposal completed with no reported problems.

    1.11 Completed Two Sets of STIS/CCD 8903 (Bias Monitor - Part 1)

        The Space Telescope Imaging Spectrograph (CCD) was used to monitor 
the bias in the 1x1, 1x2, 2x1, and 2x2 bin settings at gain=1, and 1x1 at 
gain = 4 to build up high-S/N superbiases and track the evolution of hot 
columns.  There were no problems.

    1.12 Completed STIS/CCD-2 9107 (The Fundamental Plane for Nuclear Black 
Holes)

        The Space Telescope Imaging Spectrograph (CCD)was used to conduct 
more in-depth searches for supermassive black holes in galaxy 
centers.  Previous work has led to the discoveries that {1} most or all hot 
galaxies contain massive dark objects at their centers, presumably black 
holes; {2} there is a remarkably tight correlation between the black-hole 
mass and the luminosity-weighted velocity dispersion of the hot component 
of the galaxy. This mbh-Sigma relation has a scatter which is <0.3 dex in 
mbh and consistent with zero.  This relationship suggests a strong link 
between black-hole formation, AGN activity, and galaxy formation, and once 
it is understood this link should advance our understanding of all three 
processes.  The goal of this proposal is to investigate the scatter in the 
mbh-Sigma relation and the role of possible second parameters, by examining 
a sample of galaxies at fixed velocity dispersion Sigma=200+/- 20 
kms.  This approach decouples the effects of a second parameter from 
uncertainties in the shape of the mbh-Sigma relation, and minimizes 
spurious correlations because all of the galaxies will be studied using the 
same well-tested observational and modeling techniques.  No anomalous 
activity occurred.

    1.13 Completed WF/PC-2 9087 (Black Hole X-ray Transients and X-ray 
Binaries in M31)

        The WF/PC-2 was used to search for M31 for x-ray transients which 
had previously been seen as part of the Chandra Guaranteed Time 
Observations {GTO} program.  The x-ray properties of these transient 
sources {spectra, variability} allow us to determine whether the accreting 
object is a black hole or a neutron star.  It is proposed to determine the 
nature of the mass-losing star.  Massive stars will show little {<2 mag} 
change in their UV luminosities during outbursts, while low-mass stars will 
show large {>5 mag} changes in their UV luminosities.  By determining the 
nature of the primary {accreting} and secondary stars in these x-ray 
transients, we will have the first dataset that will allow the evolution of 
black hole and neutron star binaries to be studied in an external 
galaxy.  The proposal completed nominally.

    1.14 Completed Three Sets of STIS/CCD 9312 (POMS Test Proposal: STIS 
Non-scripted Parallel Proposal Continuation IV)

        The Space Telescope Imaging Spectrograph (CCD) was used to make low 
galactic latitude, non-scripted parallel observations as part of a POMS 
test proposal.  The observations were completed as planned, and no 
anomalies were reported.
