PERIOD COVERED:  0000Z (UTC) 05/29/97 - 0000Z (UTC) 05/30/97

Daily Status Report as of 150/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed Two Sets of WF/PC-2 6802 (Cosmology With the Medium Deep
Survey)

       The WF/PC-2 was used to make observations taken in parallel with the
prime science observations as part of the Medium Deep Sky Survey.  The
observations were executed as scheduled, and no problems were reported.

   1.2 Completed Two Sets of WF/PC-2 7553 (Pure Parallel Archive Survey II)

       WF/PC-2 parallel observations were obtained in the ultraviolet in
search for interesting objects.  This program is designed to find
extragalactic sources with near ultraviolet excesses (3000 A0) outside the
galactic plane and far ultraviolet sources (1600 A0) in the galactic plane.
The procedure was executed as scheduled, and no anomalies were reported.

   1.3 Completed Two Sets of WF/PC-2 6909 (WF/PC-2 Cycle 6 Calibration:
Earth Flats

       The WF/PC-2 was used to make observations of the bright Earth to
obtain streak flats which are used to construct high quality flat fields
for the WF/PC-2 filter set.  The observations were executed as scheduled,
and no anomalies were noted.

   1.4 Completed WF/PC-2 7588 (Measuring Q0 With Type IA Supernovae)

       The WF/PC-2 was used to make observations of supernova SN1997A2 in
order to measure the Q0 parameter.  This produces a precise Hubble diagram
which can be used to measure the cosmic deceleration and global curvature
of the universe.  HST can make an essential contribution by providing
photometry with substantially higher precision and better temporal coverage
than can be obtained from the ground.  The observations were executed as
scheduled, and no anomalies were noted.

   1.5 Completed FGS 6486 (Orbits of Pre-Main Sequence Binaries)

       The FGSs were used in the TRANS mode to make astrometric
observations of the per-main sequence, binary star system ROX-42B in order
to help compute its orbital parameters.  The observations will be used to
make orbital maps of T-Tauri class stars.  From these orbital parameters
they will be able to derive the first reliable mass measurements for low
mass pre-main sequence stars.  The observations were completed as
scheduled, and no anomalies were reported.

   1.6 Completed WF/PC-2 6693 (Curcumstellar Nebulae as Fossil Records of
the Mass Loss History)

       The WF/PC-2 was used to make images of the curcumstellar nebula
surrounding the luminous blue variable star HD168625 in order to study the
fossil records of its mass loss history.  The observations were completed
as scheduled and no anomalies were reported.

   1.7 Completed STIS/CCD/MA1/MA2 7064 (STIS SMOV MAMA Contamination Monitor)

       The Space Telescope Imaging Spectrograph (CCD/MA1/MA2) was used to
make observations of the flux from standard star GRW+70D582 in order to
monitor for any gross changes over time that might indicate contamination.
The observations were completed as planned, and no anomalies were reported.

   1.8 Completed STIS/MA1 7126 (Early Release Observations of Shocked
Interstellar Gas in the Vela Supernova Remnant)

       The Space Telescope Imaging Spectrograph (MA1) was used to make
images of a hot star HD72089 which is located in back of the shocked
interstellar gas in the Vela supernova remnant.  Studies have shown
substantial variation in the amount of dust grain destruction in different
components of the shocked gas.  Therefore, this line of sight provides a
"laboratory" for learning about this important astrophysical process.  The
observations were executed as scheduled, and no anomalies were noted.

   2.3 Operations Notes:

       The Battery #3 Capacity Test continues.

       There was a NICMOS gain table uplink at 149/1230Z.

       The STIS proposal detailed in 1.8 is an early release observation.
The data from the proposal was successfully dumped to the ground.
