1.0 OBSERVATIONS SCHEDULED AND ACCOMPLISHED:

    1.1 Completed Three Sets of WF/PC-2 9042 (An Archive To Detect The 
Progenitors Of Massive, Core-Collapse Supernovae)

         The WF/PC-2 was used to search for supernovae which have massive 
star progenitors.  The already extensive HST archive and high-resolution 
ground-based images of galaxies within ~20 Mpc enables us to resolve and 
quantify their individual bright stellar content.  As massive, evolved 
stars are the most luminous single objects in a galaxy, the progenitors of 
core-collapse supernovae should be directly detectable on pre-explosion 
images.  One Type II progenitor has been observed this year, and the 
investigators have proposed a short, companion WFPC2 proposal to confirm 
this candidate and identify a second.  The observations completed nominally.

    1.2 Completed Two Sets of STIS/CCD 9285 (POMS Test Proposal: STIS 
Non-scripted Parallel Proposal Continuation III)

        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.

    1.3 Completed Two 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 Three Sets of WF/PC-2 8936 (Cycle 10 Supplemental Darks 
Pt1/3)

        The WF/PC-2 was used to perform a dark calibration program that 
obtains three dark frames every day to provide data for monitoring and 
characterizing the evolution of hot pixels.  The proposal completed with no 
reported problems.

    1.5 Completed STIS/CCD 9136 (T Tauri Star Coronagraphic Survey: A PMS 
Protoplanetary Disk Census)

      The Space Telescope Imaging Spectrograph (CCD) was used to observe 
pre-main sequence solar-mass stars, the T Tauri stars that Millimeter and 
IR studies suggest at least 50 percent have circumstellar disks similar to 
the disk from which our planetary system formed.  High spatial resolution, 
high dynamic range imaging of such systems will map the spatial 
distribution of material around the star, constraining the disk sizes and 
inclinations, and provide a first assessment of when structure in the disk, 
such as cleared central zones and annuli, which has been linked to planet 
formation, develops.  All observations completed without incident.

    1.6 Completed Two Sets of WF/PC-2 8940 (Cycle 10 Earth Flats)

        The WF/PC-2 was used to monitor flatfield stability by obtaining 
sequences of Earth streak flats to construct high quality flat fields for 
the WF/PC-2 filter set.  These flat fields will allow mapping of the OTA 
illumination pattern and will be used in conjunction with previous internal 
and external flats to generate new pipeline superflats.  The proposal 
completed without incident.

    1.7 Completed Three Sets of WF/PC-2 9244 (POMS Test Proposal: WFII 
Parallel Archive Proposal Continuation)

        The WF/PC-2 was used to perform a generic target version of the 
Archival Pure Parallel program.  The program will be used to take parallel 
images of random areas of the sky, following the recommendations of the 
Parallels Working Group.  The observations completed with no anomalous 
activity.

    1.8 Completed 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.

    1.9 Completed STIS/CCD 9066 (Closing in on the Hydrogen Reionization 
Edge of the Universe)

        The Space Telescope Imaging Spectrograph (CCD) was used in parallel 
constrain the Hydrogen reionization edge in emission that marks the 
transition from a neutral to a fully ionized IGM at a predicted 
redshifts.  The proposal completed uneventfully.

    1.10 Completed WF/PC-2 9142 (The Structure and Physics of Extragalactic 
Jets)

        The WF/PC-2 was used to perform an ongoing investigation into the 
physics of jets.  It is proposed to obtain polarimetry of the jets of 3C 
264 and 3C 78.  No problems were reported.

    1.11 Completed STIS/CCD/MA1/MA2 8919 (MAMA Sensitivity and Focus 
Monitor C10)

        The Space Telescope Imaging Spectrograph (CCD, MA1 and MA2) was 
used to monitor the sensitivity of each MAMA grating mode to detect any 
change due to contamination or other causes, and also to monitor the STIS 
focus in a spectroscopic and an imaging mode.  All observations were 
successful.

    1.12 Completed STIS/CCD/MA2 9048 (Boron Constraints on Slow Mixing in 
Low Mass Stars)

        The Space Telescope Imaging Spectrograph (CCD and MA2) was used to 
observe the atomic and nuclear characteristics of the light elements Li, Be 
and B, that make their photospheric abundances ideal tracers of internal 
physical processes in stars.  Both Li and Be have been heavily utilized to 
this end since their diminished abundances are a direct result of the 
extent of internal slow mixing between surface and interior layers, as has 
been shown with ground-based data.  Boron provides a fresh and special 
probe because it survives to greater depths inside stars than does Li or 
Be, and can thus uniquely reveal the depth of mixing.  It is proposed to 
observe B in stars with very large depletions of Li and Be, i.e. stars 
which have been the most seriously affected by mixing.  No problems occurred.

    1.13 Completed STIS/MA2 8920 (Cycle 10 MAMA Dark Measurements)

        The Space Telescope Imaging Spectrograph (MA2) was used to perform 
the routine monitoring of the MAMA detector dark noise, and is the primary 
means of checking on health of the MAMA detectors systems through frequent 
monitoring of the background count rate.  The proposal completed with no 
reported anomalous activity.
