PERIOD COVERED:  0000Z (UTC) 06/17/99 - 0000Z (UTC) 06/18/99

Daily Status Report as of 169/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed Two Sets of STIS/CCD 7949 (CCD Dark and Bias Monitor --
Cont. to June 99)

       The Space Telescope Imaging Spectrograph (CCD) was used to conduct a
CCD dark calibration and a bias monitoring program.  It was also scheduled
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.

   1.2 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.

   1.3 Completed 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.

   1.4 Completed FOC/96/WF/PC-2 7274 (Secular Changes in the Jet of M-87)

       The Faint Object Camera (f/96) and the WF/PC-2 were both used to
make observations of the secular changes in the jet coming off of the
active galactic nuclei of galaxy M-87.  Past observations with the FOC have
shown changes as small as 0.03", and provide a unique opportunity to study
proper motions and structural changes of the jet.  An internal flat
calibration image was also taken.  The observations were completed as
scheduled, and no anomalies were reported.

   1.5 Completed Five Sets of STIS/CCD 8406 (POMS Test Proposal: STIS
Non-Scripted Parallel Proposal Continuation V)

       The Space Telescope Imaging Spectrograph (CCD) was used to make high
galactic latitude observations taken in parallel with the prime science
observations as part of a POMS proposal.  This is a STIS non-scripted
parallel Condition V proposal.  The observations were completed as
scheduled, and no anomalies were reported.

   1.6 Completed WF/PC-2 8090 (POMS Test Proposal: WF-II Parallel Archive
Proposal Continuation)

       The WF/PC-2 was used in the parallel mode to make some low galactic
latitude archive observations.  The program will be used to take parallel
images of random areas of the sky.  The observations were executed as
scheduled, and no anomalies were noted.

   1.7 Completed STIS/CCD 8470 (POMS Test Proposal: STIS Non-Scripted
Parallel Proposal Continuation V)

       The Space Telescope Imaging Spectrograph (CCD) was used to make high
galactic latitude observations taken in parallel with the prime science
observations as part of a POMS proposal.  This is a STIS non-scripted
parallel Condition VI proposal.  The observations were completed as
scheduled, and no anomalies were reported.

   1.8 Completed WF/PC-2 6967 (Blue Continuum Snapshots of 3CR Radio -
Continued Galaxies)

       The WF/PC-2 was used to make observations of the radio galaxy
3C247.0.  Radio galaxies are an important class of extragalactic objects:
they represent one of the most energetic astrophysical phenomena and they
may be used as probes of their environments.  They are unique probes of the
early Universe.  The observations were completed as planned, and no
problems were reported.

   1.9 Completed WF/PC-2 6596 (Formation of Stellar Systems in Mergers in a
Compact Group of Galaxies)

       The WF/PC-2 was used to make observations of the compact group of
galaxies NGC-7319 in order to study the formation of stellar systems in
active mergers.  This detailed study will enable an evaluation of how
environmental conditions influence the nature of the stellar systems to be
formed and an assessment of the contribution of tidal dwarf formation to
the overall population of dwarf galaxies.  The observations were executed
as scheduled, and no anomalies were noted.

   1.10 Completed STIS/CCD 8189 (The Source of Gamma Ray Bursts and the
Nature of their Hosts)

       The Space Telescope Imaging Spectrograph (CCD) was used to make high
resolution optical and ultraviolet observations of the Gamma Ray Burster
(GRB) 990510 and its host galaxy.  This comprehensive set of observations
will provide new insights into the astrophysics of GRBs and their high
redshift host galaxies.  The observations were completed as planned, and no
problems were reported.
