   1.1 Completed STIS/CCD 8409 (STIS CCD Bias Monitor C8)

       The Space Telescope Imaging Spectrograph (CCD) was used to make a CCD
bias calibration observation.  This is 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 to track the evolution of hot columns.  The observations were
executed as scheduled, and no anomalies were reported.  

   1.2 Completed STIS/CCD 8408 (STIS CCD Dark Monitor C8)

       The Space Telescope Imaging Spectrograph (CCD) was used to make a CCD
bias calibration observation.  This is to monitor the darks for the STIS CCD. 
The observations were executed as scheduled, and no anomalies were reported.  

   1.3 Completed Three Sets of WF/PC-2 8443 (WF/PC-2 Cycle-8 Supplemental Darks
pt1/3)

       The WF/PC-2 was used to obtain three dark frames every day to provide
data for monitoring and characterizing the evolution of hot pixels.  The
observations were completed as planned, and no problems were reported.  

   1.4 Completed STIS/CCD 8313 (Imaging the Host Galaxies of High Redshift Type
Ia Supernovae)

       The Space Telescope Imaging Spectrograph (CCD) was used to make
observations of 963, 95116 and 97203  and its host galaxy.  The propose is to
obtain snapshot, unfiltered STIS images of distant galaxies of known redshift
which have hosted supernovae {SNe} of Type IA found via the Supernova Cosmology
Project.  The observations were completed as scheduled, and no anomalies were
reported.  

   1.5 Completed Two Sets of WF/PC-2 8441 (WF/PC-2 Decontaminations and
Associated Observations Pt. 1/2)

       The WF/PC-2 was used to make its monthly decontamination operations. 
Also included are instrument monitors tied to decons: photometric stability
check, focus monitor, pre- and post-decon internals {bias, internal flats,
k-spots, and darks}, and ultraviolet throughput checks.  The observations were
executed as scheduled, and no anomalies were noted.  

   1.6 Completed WF/PC-2 8458 (WFPC2 Cycle 8 Plate Scale Verification)

       The WF/PC-2 was used to make observations of object NGC-2100 as part of
a Cycle 8 Plate Scale Verification in the red and ultraviolet bands.  The
observations were executed as scheduled, and no anomalies were noted.  

   1.7 Completed STIS/MA2 8429 (Cycle 8 Plate Scale Verification)

       The Space Telescope Imaging Spectrograph (MA2) was used to conduct a
Cycle 8 plate scale calibration verification. The calibration was completed as
scheduled, and no anomalies were reported.  

   1.8 Completed WF/PC-2 8216 (T Tauri Star Snapshot Survey II. Completing the
CTTs Sample)

       The WF/PC-2 was used to make observations of the T-Tauri class star
known as HN-12 as part of Snapshot Survey II.  This database will be of
fundamental importance to understanding the nature of planet-forming
environments and their frequency in the galaxy.  The observations were executed
as scheduled, and no anomalies were noted.  

   1.9 Completed STIS/CCD 8549 (POMS Test Proposal: STIS non-scripted parallel
proposal continuation III)

       The Space Telescope Imaging Spectrograph (CCD) was used to make high
galactic latitude observations as part of a non-scripted POMS Test Proposal.
The observations were completed as scheduled, and no problems were reported.  

   1.10 Completed STIS/CCD/MA2 8341 (UV Spectroscopy of M33-X8: mini-AGN or
black-hole binary?)

       The Space Telescope Imaging Spectrograph (CCD and MA2) was used to make
observations of the nuclear region of galaxy M-33 known as X-8 in order to
determine if it is a mini-AGN or a binary black-hole.  X-8 is the most luminous
steady X- ray source in the Local Group.  A wavelength calibration image was
also taken.  The observations were executed as scheduled, and no anomalies were
noted.  

   1.11 Completed Four Sets of WF/PC-2 8457 (UV Earthflats)

       The WF/PC-2 was used to make a ultraviolet Earth flat calibration
image.  This is to improve the quality of pipeline the ultraviolet flatfields. 
The observations were completed as scheduled, and no problems were reported.  

   1.12 Completed WF/PC-2 8090 (POMS Test Proposal: WF-II Parallel Archive
Proposal Continuation)

       The WF/PC-2 was used in the parallel mode to make some low galactic
latitude archive observations.  The program will be used to take parallel
images of random areas of the sky.  The observations were executed as
scheduled, and no anomalies were noted.  

   1.13 Completed WF/PC-2 8085 (Imaging of High Redshift Starburst Galaxies in
the Light of Lyman-Alpha)

       The WF/PC-2 was used to make Lyman-Alpha wavelength observations of the
high redshifted starbursting galaxy Q0201-365.  The observations were completed
as planned, and no anomalies were reported.  

   1.14 Completed Two Sets of STIS/CCD 8406 (POMS Test Proposal: STIS
Non-Scripted Parallel Proposal Continuation V)

       The Space Telescope Imaging Spectrograph (CCD) was used to make high
galactic latitude observations taken in parallel with the prime science
observations as part of a POMS proposal.  This is a STIS non-scripted parallel
Condition V proposal.  The observations were completed as scheduled, and no
anomalies were reported.

Central Cluster Galaxies)

       The WF/PC-2 was used to make snapshot survey observations of the x-ray,
central cluster galaxies A1033 and A1068.  Central cluster galaxies are the
most massive stellar systems known and have been used as standard candles for
many decades.  The observations were executed as scheduled, and no anomalies
were noted. 

   1.17 Completed WF/PC-2 8436 (POMS Test Proposal: WFII Backup Parallel
Archive Proposal II)

       The WF/PC-2 was used to make archive observations parallel to the prime
science observations as part of a POMS test proposal.  This is a POMS test
proposal designed to simulate scientific plans.  The observations were
completed as planned, and no anomalies were reported.
