PERIOD COVERED:  0000Z (UTC) 09/22/98 - 0000Z (UTC) 09/23/98

Daily Status Report as of 266/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed Three Sets of WF/PC-2 7712 (WF/PC-2 Cycle 7 Supplemental
Darks pt2/3)

       The WF/PC-2 was used to make a series of Cycle 7 supplemental
calibration darks.  This dark calibration program obtains 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.

   1.2 Completed Two Sets of STIS/CCD 7948 (CCD Dark and Bias Monitor --
Cont. to Dec. 98)

       The Space Telescope Imaging Spectrograph (CCD) was used to measure
CCD dark current and bias rates for the two supported amplifier settings
{GAIN=1 and GAIN=4} in order to gather data for making superdarks and
superbiases.  The data will be used to track the growth of hot pixels on
the CCD in general and within the various target acquisition apertures
specifically.  During the final iteration of this proposal, the acquisition
failure described in yesterday's report and in HSTAR 6690 occurred,
affecting eight observations.  Otherwise, the observations were executed as
scheduled, and no further anomalies were noted.

   1.3 Completed STIS/CCD/MA2 8070 (Throughput of NUV filters)

       The Space Telescope Imaging Spectrograph (CCD and MA2) was used to
make observations of HS2027+065 in order to measure the throughput of the
near ultraviolet filters.  The purpose is to measure the absolute
sensitivity of the NUVMAMA imaging modes with the CN182, CN270, MGII, and
CIII filters.  A wave length calibration image was also taken.  The
observations were executed as scheduled, and no anomalies were noted.

   1.4 Completed WF/PC-2 6827 (The Enigmatic Soft Gamma-Ray Repeaters)

       The WF/PC-2 was to be used to make observations of object
N49-052601, the optical/ultraviolet counterpart to a enigmatic soft
gamma-ray Repeater.  This is the most enigmatic of a class of sources,
which, for reasons unknown, repeatedly show high-energy bursts.  During
this proposal, the acquisition failure described in yesterday's report and
in HSTAR 6690 occurred, affecting twenty-six observations.

   1.5 Completed Three Sets of NIC/2/3 8082 (NICMOS pure parallel Fall 98)

       The Near Infrared Camera (Cameras Two and Three) was used to make
pure parallel observations while another instrument is prime.  During the
first iteration of this proposal, the acquisition failure described in
yesterday's report and in HSTAR 6690 occurred, affecting seven
observations.  Otherwise, the observations were executed as scheduled, and
no further anomalies were noted.

   1.6 Completed Three Sets of STIS/CCD 7912 (STIS Parallel Archive
Proposal - Nearby Galaxies - Imaging and Spectroscopy)

       The Space Telescope Imaging Spectrograph (CCD) was used to make
parallel observations of nearby galaxies.  This survey will be useful to
study the star formation histories, chemical evolution, and distances to
these galaxies.  These data will be placed immediately into the Hubble Data
Archive.  The observations were completed as scheduled, and no problems
were reported.

   1.7 Completed Five Sets of WF/PC-2 7909 (POMS Test Proposal: WF II
Parallel Archive Proposal)

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

   1.8 Completed WF/PC-2 8061 (POMS Test Proposal: WF-II Backup Parallel
Archive Proposal)

       This is a POMS test proposal designed to simulate scientific plans.
The proposal was executed as planned, and no anomalies were reported.

   1.9 Completed Six Sets of STIS/CCD 8062 (POMS Test Proposal: STIS
Non-Scripted Parallel Proposal Continuation)

       The Space Telescope Imaging Spectrograph (CCD) was used to make high
galactic latitude observations take in parallel with the prime science
observations.  The observations were completed as planned, and no problems
were reported.

   1.10 Completed Four Sets of NIC/2/3 8063 (NICMOS Pure Parallel Sponge -
Backup)

       The Near Infrared Camera (Cameras Two and Three) was used to make
observations taken in parallel with the prime science observations.  This
proposal is PRE-the new FOM default.  The observations were executed as
scheduled, and no anomalies were noted.

   1.11 Completed STIS/CCD 8080 (STIS Spectroscopic CCD Flatfielding --
Revised)

       The Space Telescope Imaging Spectrograph (CCD) was used to make CCD
flat fielding calibration observations in the spectroscopic mode.  The
observations were completed as planned, and no anomalies were reported.

   1.12 Completed NIC/2 7897 (Probing Planetary Formation Around
Main-Sequence Stars: A Snapshot Survey)

       The Near Infrared Camera (Camera Two) was used to make snapshort
survey images of the main sequence star HR333 probing for planetary
formation.  The IR excess main-sequence stars host cool circumstellar dust
disks, which are most likely replenished by the debris of unseen
planetesimals.  The observations were completed as scheduled, and no
problems were noted.

   1.13 Completed FGS 7597 (Long Term Stability of Transfer Scan Mode in
FGS-1R)

       The Fine Guidance Sensors (FGS-1R) was used to make observations of
the standard star UPGREN69 in order to study the long term stability of the
Transfer Scan Mode.  The observations were executed as scheduled, and no
anomalies were noted.

   1.14 Completed NIC/2 7834 (A Search for Giant Planets Around Very Young
Nearby Late-type Dwarfs)

       The Near Infrared Camera (Camera Two) was used to make observations
of the very young, late-type, dwarf star HD36705 as part of a search for
large planets.  Very young late-type dwarfs at distances closer than 30 pc
are excellent sites to provide a direct detection of extrasolar planets.
The observations were executed as scheduled, and no anomalies were noted.

   1.15 Completed NIC/1 7870 (NICMOS Observations of FSC10214+4724: Mapping
a Redshift 2.3 Quasar With 100 Parsec Resolution)

       The Near Infrared Camera (Camera One) was used to make mapping
observations of quasar FSC10214+4 (Which has a redshift of 2.3).  Our
existing WF/PC-2 data provides compelling evidence that th1s luminous IRAS
source is a gravitationally lensed quasar.  The observations were completed
as planned, and no anomalies were reported.

   1.16 Completed STIS/CCD 8064 (POMS Test Proposal: STIS Non-Scripted
Parallel Proposal - Backup)

       The Space Telescope Imaging Spectrograph (CCD) was used to conduct a
non-scripted parallel POMS test.  The observations were completed as
scheduled, and no problems were reported.
