PERIOD COVERED:  0000Z (UTC) 09/05/97 - 0000Z (UTC) 09/08/97

Daily Status Report as of 251/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed Three Sets of 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.

   1.2 Completed Six Sets of 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.

   1.3 Completed Twelve Sets of NIC/1/2/3 7726 (NICMOS One Orbit Parallel)

       The Near Infrared Camera (Cameras One, Two and Three) was used to
make one orbit parallel calibration observations.  The observations were
executed as scheduled, and no anomalies were noted.

   1.4 Completed NIC/1/2 7690 (NICMOS Pointed Super Flats)

       The Near Infrared Camera (Cameras One and Two) was used to make
super flat field calibration observations.  The observations will be used
to build high signal/noise ratio NICMOS flat fields for the different
filters.  The observations were executed as scheduled, and no anomalies
were noted.

   1.5 Completed 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.

   1.6 Completed WF/PC-2 6460 (Where are the Dozens of Predicted
Cataclysmic Variables in Globular Clusters?)

       The WF/PC-2 was used to make observations of the globular cluster
NGC-6093 in order to search for predicted cataclysmic variables.  WF/PC-2
imaging of globular cluster cores provides us with a unique opportunity to
detect erupting cataclysmic variables because they should be relatively
common in the core region.  The observations were executed as scheduled,
and no anomalies were noted.

   1.7 Completed WF/PC-2 6517 (The Formation of the Inner Galactic Halo)

        The WF/PC-2 was used to make observations of the galaxy NGC-6652 in
order to study the formation of its inner galactic halo.  These
observations will be used to derive a precise color-magnitude diagram in
order to obtain an accurate age and hence, determine the formation
chronology of the inner halo.  The observations were executed as schedule,
and no anomalies were noted.

   1.8 Completed NIC/2 7325 (The Small Scale Structure of Protostellar
Disks and Infall Envelopes)

       The Near Infrared Camera (Camera Two) was used to make images of the
protostellar system IRAS04365 in order to study its small scale structure
of the disk and infall envelope.  HST has provided striking images of
circumstellar disks towards young stars, as seen silhouetted in absorption
against bright nebular backgrounds.  The advent of the near-infrared NICMOS
camera on HST brings subarcsecond imaging to even younger sources,
protostars.  The observations were executed as scheduled, and no anomalies
were noted.

   1.9 Completed WF/PC-2 6431 (Determination of the Extragalactric Distance
Scale)

       The WF/PC-2 was used to make observations of the galaxy NGC-1326 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.

   1.10 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.

   1.11 Completed NIC/1/2/3 7328 (High Resolution IR Imaging Survey of the
Centers of the Nearest Active Galaxies)

       The Near Infrared Camera (Camera One, Two and Three) was used to
make high resolution infrared observations of the nearest active galaxy
Markarian 5 in order to study its inner nuclear region.  Observing in the
near-IR minimizes the dust obstruction and maximizes sensitivity to the old
stellar population which dominates the mass.  The observations were
executed as scheduled, and no anomalies were noted.

   1.12 Completed WF/PC-2 5946 (The Stellar Populations of Low Surface
Brightness Galaxies)

       The WF/PC-2 was used to make observations of the low surface
brightness of radio galaxy 3C324.  The objective of this program is to
study the stellar population and evolution of this galaxy.  The
observations were completed as planned, and no anomalies were reported.

   1.13 Completed Two Sets of NIC/2 7420 (A Near-Infrared Search for Very
Low Mass Companions to Stars Within 10 Parsecs of the Sun)

       The Near Infrared Camera (Camera Two) was used to make searching
observations for very low mass companions to variable stars LHS3233 and
CD-46D1154. These stars are known to be within 10 parsecs of the Sun.  The
observations were executed as scheduled, and no anomalies were noted.

   1.14 Completed Two Sets of NIC/1/2/3 7447 (The Cosmological Evolution of
Quasar Host Galaxies)

       The Near Infrared Camera (Cameras One, Two and Three) was used to
make observations of galaxy SGP3-39 as part of a survey to study the
cosmological evolution of galaxies which host quasars.  Other point spread
function observations were taken to test the calibration of the cameras.
The observations were executed as scheduled, and no anomalies were noted.

   1.15 Completed FGS 6879 (Parallax of TV-Col)

       The FGSs were used to make astrometric observations of the x-ray
variable star TV-Col to obtain its precise parallax measurements.  The
observations were executed as scheduled, and no anomalies were noted.

   1.16 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 galaxies NGC-3898 and NGC-2748.
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.

   1.17 Completed NIC/2/3 7460 (The Nature of Red Outlier Galaxies: Age vs
Dust)

       The near Infrared Camera (Cameras Two and Three) was used to make
observations of red outlier galaxy GAL-141743.  It is  expected that
high-resolution imaging in the near-infrared will reveal the central region
to be very concentrated compared to the optical.  The observations were
completed as planned, and no problems were reported.

   1.18 Completed WF/PC-2 6936 (UV Throughput)

       The WF/PC-2 was used to make ultraviolet observations of the
standard star BD+75D325 in order to measure the system's throughput.  These
observations will be used to determine the wavelength dependence of the
throughput across the bandpass.  The observations were executed as
scheduled, and no anomalies were noted.

   1.19 Completed FOC/96 6416 (FOC Imaging of the Dusty Envelopes of
Mass-Losing Supergiants)

       The Faint Object Camera (f/96) was used to make images of the dusty
envelope surrounding the variable mass-losing supergiant star HD179821.
This is to define the role that mass loss plays in determining the fate of
supernova (SN) progenitors and SN remnants.  Current stellar evolution
theory indicates that all stars with mass larger then 10 solar masses will
produce a SN.  The observations were executed as scheduled, and no
anomalies were noted.

   1.20 Completed WF/PC-2 6159 (Giant H-II Regions in NGC-6822)

       The WF/PC-2 was used to make observations of the H-II regions in
galaxy NGC-6822.  Giant H-II regions in external galaxies represent centers
of young massive star formation and their structure may indicate the
process of progressive star formation.  The observations were completed as
scheduled, and no problems were reported.

   1.21 Completed FGS 7487 (Orbits of Pre-Main Sequence Binaries)

       The Fine Guidance Sensors were used to make astrometric observations
of the pre-main-sequence, binary star HV Tau in order to determine its
orbital elements.  This is important because there are still no low mass
young stars with reliably known masses.  The observations were executed as
scheduled, and no anomalies were noted.
