PERIOD COVERED:  0000Z (UTC) 07/16/98 - 0000Z (UTC) 07/17/98

Daily Status Report as of 198/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed Two 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 NIC/2 7853 (Deep IR Imaging of Two Gas-Rich Radio Galaxies)

       The Near Infrared Camera (Camera Two) was used to make high
resolution continuum, line and polarization images of the gas-rich radio
galaxy 3C305.  This is to obtain a deep IR image to locate the true nuclei
and clarify the structure of the galaxies in order to test merger models.
The observations were executed as scheduled, and no anomalies were noted.

   1.3 Completed Three 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.

   1.4 Completed STIS/CCD 7910 (STIS Extragalactic Parallel Survey)

       The Space Telescope Imaging Spectrograph (CCD) was used to make
extragalactic slitless spectrographic observations as part of the parallel
high galactic latitude survey to search for emission line galaxies.  Data
was taken in parallel, and are not subject to proprietary time.  The
observations were executed as scheduled, and no anomalies were noted.

   1.5 Completed WF/PC-2 7622 (WF/PC-2 Cycle 7 Internal Monitor)

       The WF/PC-2 was used to make a set of Cycle 7 internal monitoring
calibration measurements.  A variety of internal exposures are obtained in
order to provide a monitor of the integrity of the CCD camera electronics
in both bays {gain 7 and gain 15}, a test for quantum efficiency in the
CCDs, and a monitor for possible buildup of contaminants on the CCD
windows.  A bias calibration and an internal flat calibration image were
also taken.  The observations were executed as scheduled, and no anomalies
were noted.

   1.6 Completed NIC/1/2/3 7883 (Infrared Imaging of High Redshift {0.4 <=
z <= 1} Tully-Fisher Galaxies)

       The Near Infrared Camera (Cameras One, Two and Three) was used to
make observations of the high redshifted Tully-
Fisher class galaxy GSS-072-74.  With the advent of 10 meter class
telescopes combined with the high spatial resolution of the HST, it is now
possible to study the internal kinematics and structural properties of
galaxies out to a redshift of z ~ 1.  The observations were completed as
planned, and no anomalies were reported.

   1.7 Completed Three Sets of STIS/CCD 7908 (POMS Test Proposal: STIS
Non-Scripted Parallel Proposal)

       The Space Telescope Imaging Spectrograph (CCD) was used to make
calibration observations as part of the POMS Test Proposal.  This was a
STIS non-scripted parallel proposal.  The observations were completed as
planned, and no problems were reported.

   1.8 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.

   1.9 Completed NIC/1/2/3 7596 (NICMOS MULTIACCUM Dark Characterization)

       The Near-Infrared Camera Multi-Object Spectrograph (Cameras One, Two
and Three) was used to make a NICMOS MULTIACCUM dark characterization.  The
purpose of this proposal is to monitor the darks using three different
MULTIACCUM sequences.  The observations were executed as scheduled, and no
anomalies were noted.

   1.10 Completed Two Sets of WF/PC-2 7616 (Rapid Response to Anomalous
Activity in Jupiter's Atmosphere)

       The WF/PC-2 was used to make observations of anomalous activity in
the atmosphere of the planet Jupiter.  The well-documented record of
aperiodic disturbances within Jupiter's atmosphere reveals that their onset
is marked by an intensely white cloud that expands and interacts with the
local winds.  The observations were completed as planned, and no problems
were reported.

   1.11 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.  The observations were executed as scheduled, and no
anomalies were noted.

   1.12 Completed NIC/1/2/3 7896 (A NIR Snapshot Survey of Ultraluminous IR
Galaxies)

       The Near Infrared Camera (Cameras One, Two and Three) was used to
make snapshot survey observations of the ultraluminous infrared galaxy
IR20087-03.  Nearly all of these galaxies show evidence for a recent tidal
interaction, and we will search for evidence of the merger progenitors near
the center of each galaxy, a task made significantly easier with NIR
imaging.  The observations were completed as planned, and no anomalies were
noted.

   1.13 Completed NIC/2 7233 (Dust Disks Around Main Sequence Stars)

       The Near Infrared Camera (Camera Two) was used to make observations
of the dust disk around the main sequence star TWA8B.  The observations
were made with the coronagraph to minimize the effects of glare from the
bright central star.  A dark calibration image was also taken.  The
observations were completed as scheduled, and no anomalies were reported.

   1.14 Completed WF/PC-2/NIC/1/2/STIS/CCD/MA2 7560 (STIS GTO Observations)

       The WF/PC-2, the Near Infrared Camera (Cameras One and Two) and the
Space Telescope Imaging Spectrograph (CCD and MA2) were used to make
observations  of galaxy NGC-3995.  The solar blind and long slit
capabilities of STIS will be used to investigate the population of hot
stars in galaxies.  The observations were executed as scheduled, and no
anomalies were noted.

   1.15 Completed 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 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.

   1.16 Completed NIC/1/2 7227 (A Search for Low Mass/Sub-Luminous
Companions to M-Stars)

       The Near Infrared Camera (Camera One and Two) was used to make a
search for low mass/sub-luminous companions to the low mass M class star
LHS3003.  Knowledge of stellar and sub-stellar masses and luminosities at
and below the ~0.08 M{sun} H-burning limit is of fundamental importance.  A
dark calibration image was also taken.  The observations were completed as
planned, and no problems were reported.

   1.17 Completed NIC/1/2/3 7886 (NICMOS Snap Shot Survey of Early-Type
Galaxies)

       The Near Infrared Camera (Cameras One, Two and Three) was used to
make observations of the early-type galaxy NGC-4636 as part of a snap-shot
broad-band imaging survey.  Since almost all early-type galaxies harbor
dust, these images which are less sensitive to extinction and will provide
superior light profiles for dynamical studies of the cores of these
galaxies.  The observations were completed as scheduled, and no problems
were reported.

   1.18 Completed FOC/96 7923 (FOC F/96 Turnon)

       The Faint Object Camera (f/96) was used to take an internal flat and
a dark to ensure that the 30-day limit for the FOC is not exceeded.  The
observations were executed as scheduled, and no anomalies were noted.
