PERIOD COVERED:  0000Z (UTC) 09/15/97 - 0000Z (UTC) 09/16/97

Daily Status Report as of 259/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed WF/PC-2/NIC/2 7446 (The Fossil Starburst in M-82)

       The WF/PC-2 and the Near Infrared Camera (Camera Two) were used to
make observations of the Galaxy M-82 (A.K.A., NGC-3034 Section B-1) which
is irregular galaxy located in Ursa Major.  There is good evidence that
M-82, the prototype starburst galaxy, has suffered two starburst episodes.
The observations were executed as scheduled, and no anomalies were noted.

   1.2 Completed Two Sets of STIS/CCD 7781 (STIS Non-Scripted Parallel
Archive Proposal - Full Orbit)

       The Space Telescope Imaging Spectrograph (CCD) was used for a
non-scripted parallel archive proposal (one full orbit).  The observations
were executed as scheduled, and no anomalies were noted.

   1.3 Completed Four Sets of STIS/CCD 7782 (STIS Non-Scripted Parallel
Archive Proposal - Half Orbit)

       The Space Telescope Imaging Spectrograph (CCD) was used for a
non-scripted parallel archive proposal (one-half orbit).  The observations
were executed as scheduled, and no anomalies were noted.

   1.4 Completed Four Sets of STIS/CCD 7783 (STIS Parallel Science)

       The Space Telescope Imaging Spectrograph (CCD) was used to make
observations taken in parallel with the prime science.  The observations
were completed , and no problems were reported.

   1.5 Completed STIS/CCD 7659 (Daily Darks to Update Acquisition Bad Pixel
Table)

       The Space Telescope Imaging Spectrograph (CCD) was used to make dark
calibration images in order to update the acquisition bad pixel table.
Daily hot pixel lists can also be used for science data analysis.  The
observations were executed as scheduled, and no anomalies were noted.

   1.6 Completed WF/PC-2 7621 (WF/PC-2 Cycle 7 Supplemental Darks PT1/3)

       The WF/PC-2 was used to make supplemental dark calibration images.
This set of calibrations is intended to obtain three dark frames every day
to provide data for monitoring and characterizing the evolution of hot
pixels.  The observations were executed as scheduled, and no anomalies were
noted.

   1.7 Completed WF/PC-2 7619 (WF/PC-2 Cycle 7 Decontamination)

       The WF/PC-2 was used to conduct a Cycle 7 decontamination procedure.
Ultraviolet-blocking contaminants are removed, and hot pixels cured, by
warming the CCDs to +20C for 6 hours.  A variety of internal images are
taken before and after the decontamination in order to verify its success
and to monitor the instrument health.  The procedures were conducted as
scheduled, and no problems were reported.

   1.8 Completed STIS/CCD 7635 (STIS CCD Hot Pixel Annealing)

       The Space Telescope Imaging Spectrograph (CCD) was used to test the
hot pixel annealing procedure.  The effectiveness of the CCD hot pixel
annealing process is assessed by measuring the dark current behavior before
and after annealing and by searching for any window contamination effects.
The observations were completed as planned, and no problems were reported.

   1.9 Completed Two Sets of STIS/MA2 7604 (Cycle 7 MAMA Dark Measurements)

       The Space Telescope Imaging Spectrograph (MA2) was used to make MAMA
dark measurements.  These darks will be used in later image reductions and
also will be trended over the instrument's life time as an indicator of the
detector's degradation or damage.  The observations were completed as
scheduled, and no problems were reported.

   1.10 Completed Two Sets of NIC/1/2/3 7793 (NICMOS MULTIACCUM Dark
Characterization)

       The Near Infrared Camera and Multi-Object Spectrometer (NICMOS) was
used to obtain on-orbit darks for the SCAMRR and STEP 256 sample sequences
after the flight software change for the pedestal effect on day 233.  The
observations were completed as planned, and no anomalies were reported.

   1.11 Completed STIS/CCD/MA1/MA2 7096 (STIS MAMA Sensitivity on Axis)

       The Space Telescope Imaging Spectrograph (CCD/MA1/MA2) were used to
make observations of BD+75D325 and GD153 in order to measure STIS
sensitivity as a function of wavelength near the center of the detector for
all spectroscopic modes, and check transmissions of all filters and
filtered slits.  The observations were executed as scheduled, and no
anomalies were noted.

   1.12 Completed FGS 6486 (Orbits of Pre-Main Sequence Binaries)

       The FGSs were used in the TRANS mode to make astrometric
observations of the per-main sequence, binary star system ZZ Tau  in order
to help compute its orbital parameters.  The observations will be used to
make orbital maps of T-Tauri class stars.  From these orbital parameters
the first reliable mass measurements for low mass pre-main sequence stars
will be derived.  The observations were completed as scheduled, and no
anomalies were reported.

   1.13 Completed NIC/1/2/3 7729 (NICMOS Short One Orbit Parallel)

       The Near Infrared Camera (Cameras One, Two, and Three) was used to
obtain "JHK" imaging of sky regions while another instrument was prime.
These observations were  part of the short NICMOS one-orbit parallel
program.  The observations were executed as scheduled, and no anomalies
were noted.

   2.3 Operations Notes:

       An automatic map using FHST-2 was scheduled for 258/143352Z.
However, the occultation report indicated that FHST-2 would be occulted by
either or both the sun and the moon from 258/0029Z until 258/1610Z, and
occulted by the moon during the subject map from 258/1433Z until 258/1522Z.
Accordingly, by ops request, the shutter for FHST-2 was closed at
258/143310Z.  Target suppress was not active at the time of the shutter
closure.  HSTAR 6168 was written.

       The EDAC RAM was dumped at 258/2106Z.

3.0 SIGNIFICANT FORTHCOMING EVENTS:

       The first SM3 Servicing Mission Operations Working Group (SMOWG) is
scheduled for today and tomorrow.
