PERIOD COVERED:  0000Z (UTC) 12/09/97 - 0000Z (UTC) 12/10/97

Daily Status Report as of 344/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed STIS/CCD 7646 (STIS CCD Scattered Light Near Earth Limb)

       The Space Telescope Imaging Spectrograph (CCD) was used to study
scattered light near the Earth's limb.  This program will determine the
effect of scattered light from the bright limb of the Earth on the
background of STIS CCD images.  The observations were executed as
scheduled, and no anomalies were noted.

   1.2 Completed WF/PC-2 6963 (OTA Calibration at Low Limb Angle)

       The WF/PC-2 was used to make calibration observations of the OTA at
low limb angles which is detected in two filters in all four chips to
determine received intensity over the range of 15.5 to 20 degrees.  The
observations were completed as planned, and no anomalies were reported.

   1.3 Completed WF/PC-2/STIS/CCD/NIC/2/3 7587 (Ionization Structure of
SN1987A Circumstellar Ring System)

       The WF/PC-2, Space Telescope Imaging Spectrograph (CCD), and the
Near Infrared Camera (Cameras Two and Three) were used to make observations
of the super nova LMC-SN1987 and its circumstellar material which is
located in the Large Magellanic Cloud.  These data will create spatially
resolved maps of the circumstellar gas in important emission lines to
determine the ionization and density structure of the inner ring.   A
wavelength calibration observation was also taken.  The observations were
completed as scheduled, and no anomalies were reported.

   1.4 Completed Two Sets of WF/PC-2 7786 (Pure Parallel Archive Survey -
Continuation)

       The WF/PC-2 was used to make observations as part of an archival
survey program in which the images were taken in parallel with the prime
science observations.  These WF/PC-2 parallel observations were obtained in
the ultraviolet in a search for interesting objects.  The observations were
completed as planned, and no problems were reported.

   1.5 Completed Two Sets of WF/P-2 6254 (GTO Pure Parallel Program - Cycle 5)

       The WF/PC-2 was use to make random long exposures of high galactic
fields taken in parallel with the prime science observations to obtain a
random sample of galaxies.  The observations were executed as scheduled,
and no anomalies were noted.

   1.6 Completed STIS/CCD 7802 (Daily Darks to Update Acquisition Bad Pixel
Table)

       The Space Telescope Imaging Spectrograph (CCD) was used to make
calibration observations to obtain daily darks to update the acquisition
bad pixel table.  These darks are intended to identify hot pixels for
update to the acquisition on-board FSW hot 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.

   1.7 Completed Two Sets of WF/PC-2 6431 (Determination of the
Extragalactric Distance Scale)

       The WF/PC-2 was used to make observations of the galaxy NGC-224 to
be used in measuring the periods of Cepheid variable stars within this
galaxy.  This will allow for a more accurate estimate of the distances to
these galaxies through the period-luminosity relation for the Cepheid
stars.  The observations were executed as scheduled, and no anomalies were
noted.

   1.8 Completed Three 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.

   1.9 Completed Three Sets of NIC/2/3 7812 (NICMOS Modified Short One
Orbit Parallel)

       The Near Infrared Camera (Cameras Two and Three) was used to obtain
"JH" imaging of sky regions when another instrument is prime.  Two dither
positions are obtained for each filter.  The observations were completed as
scheduled, and no anomalies were reported.

   1.10 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.

   1.11 Completed FGS 7682 (FGS-3 Blue Transfer Function Reference Search
Calibration)

       The Fine Guidance Sensor-3 was used to make observations of
candidate star HD68657 in order to perform the blue transfer function
reference search calibration.  This proposal will measure the transfer
function of a number of blue candidate stars in order to verify a single
star which can be used for the blue calibration of the trans mode.  The
observations were exected as scheduled, and no anomalies were reported.

   1.12 Completed Two Sets of NIC/2/3 7811 (NICMOS Modified One Orbit Parallel)

       The Near Infrared Camera (Cameras Two and Three) was used to obtain
"JH" imaging, and G096 and G141 spectroscopy of sky regions when another
instrument is prime.  The observations were completed as planned, and no
anomalies were reported.

   1.13 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.

   1.14 Completed WF/PC-2 6716 (The Pattern of Massive Star Formation in
Irregular and Amorphous Galaxies)

       The WF/PC-2 was used to make observations of the galaxy NGC-4214.
The objective is to obtain deep WF/PC-2 images in far-ultraviolet (~1700
A0), U , V, and I bandpasses of the stellar populations in four nearby
galaxies known from their observed far-ultraviolet luminosities to be
forming massive class stars.  The observations were completed as planned,
and no anomalies were reported.

   1.15 Completed STIS/CC 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.

   1.16 Completed 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.

   1.17 Completed NIC/2 7219 (Ultraluminous Infrared Galaxies)

       The Near Infrared Camera (Camera Two) was used to make observations
of the ultraluminous infrared galaxy IRAS17208.  The luminous IRAS galaxies
are probably powered by nuclear starbursts and/or central AGNs: many of
these systems exhibit evidence of recent galactic interaction or merging.
The observations were completed as planned, and no problems were reported.

   1.18 Completed NIC/2 7331 (Near-IR Properties of the Bulges of Spiral
Galaxies)

       The Near Infrared Camera (Camera Two) was used to make infrared
observations of the bulge in spiral galaxy ESO290G26.  Near-IR data at HST
resolution are essential for correcting for the effect of dust and will
enable us to derive robust nuclear properties for the sample.  The
observations were executed as scheduled, and no anomalies were noted.

   1.19 Completed STIS/MA1 7575 (The He-II Gunn-Peterson Test)

       The Space Telescope Imaging Spectrograph (MA1) was used to make
observations of the quasar Q0202-0019 in order to conduct the Gunn-Peterson
Test.  A wavelength calibration observation was also taken.  The
observations were completed as scheduled, and no anomalies were noted.
