Daily Status Report as of 154/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 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 is to produce 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.

   1.2 Completed Five Sets of NIC/3 7611 (NICMOS Parallel Thermal
Background Test)

       The Near Infrared Camera (Camera Three) was used to make
observations of an object designated a Target-1 in order to conduct a
parallel thermal background test.  This test was conducted in order to
measurement of the stability of the HST thermal emission.  The observations
were executed as scheduled, and no anomalies were noted.

   1.3 Completed Four Sets of STIS/CCD 7675 (STIS Non-Scripted Parallel
Archive Proposal)

       The Space Telescope Imaging Spectrograph (CCD) was used in the
parallel mode to obtain slitless spectroscopy with the G750L grism to
search for emission line galaxies at intermediate to high redshift.  The
observations were completed as planned, and no anomalies were reported.

   1.4 Completed NIC/1/2/3 7701 (NICMOS Short One Orbit Parallel)

       The Near Infrared Camera (Cameras One, Two and Three) was used as
part of a short NICMOS one orbit parallel program, to obtain "JHK" imaging
of sky regions when another instrument is prime.  The observations were
completed as scheduled, and no anomalies were reported.

   1.5 Completed WF/PC-2 6887 (A Photometric Search for Faint Companions to
Nearby Stars)

       The WF/PC-2 was used to make photometric search observations of the
nearby star HD95735 in order to look for possible companions.  The
technique involves use of the Planetary Camera with wide band pass filters
to photometrically measure for the presence of resolved dark companions.
The observations were executed as scheduled, and no anomalies were noted.

   1.6 Completed Six Sets of STIS/CCD 7092 (CCD Dark Rate and Read Noise)

       Observations were taken to measure CCD dark current and gather data
for making super darks. The observations were completed as planned, and no
anomalies were reported.

   1.7 Completed NIC/1 7225 (Proper Motion of Stars Near SGR-A*)

       The Near Infrared Camera (Camera One) was used to make astrometric
proper motion observations of stars in the vicinity of Sagittarius-A
(a.k.a., NGC-4147).  NGC-4147 may be a black hole with a mass close to a
million solar masses.  The observations were completed as planned, and no
anomalies were reported.

   1.8 Completed Three 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.

   1.9 Completed WF/PC-2 6469 (Pyramid Imaging of Circumstellar Material
About Nearby Stars)

       The WF/PC-2 was used to make observations of the circumstellar
material around the nearby star HD102647.  The WF/PC-2 pyramid was used as
a coronagraph to detect the circumstellar material.  The observations were
executed as scheduled, and no anomalies were noted.

   1.10 Completed Four Sets of NIC/1/2/3 7676 (NICMOS-One Orbit Parallel)

       The Near Infrared Camera (Cameras One, Two and Three) was used to
conduct an on-orbit calibration procedure.  This was done in parallel with
the prime science observations.  The procedure was completed as scheduled,
and no anomalies were noted.

   1.11 Completed WF/PC-2 6659 (A Search For Superplanets Around Weak T-
Tauri Stars)

       The WF/PC-2 was used to make observations in the one micron band of
the T-Tauri class star HBC636 in order to search for superplanets.  Weak
T-Tauri class stars are thought to have dissipated their circumstellar
disks recently, possibly by forming planetary systems.  The observations
were completed as planned, and no anomalies were reported.

   1.12 Completed Two Sets of STIS/CCD 7702 (Observations of a Possible
Optical Counterpart - GRB970508)

       The Space Telescope Imaging Spectrograph (CCD) was used to make
observations of the optical counterpart to GRB7970508.  This was to make
very deep high-resolution images with STIS CCDs covering the location of
the optical transient and also to use H-band imaging with the NICMOS Camera
Two.  The observations were completed as planned, and no anomalies were
reported.

   1.13 Completed WF/PC-2 6906 (WF/PC-2 Cycle 6 Calibration: Internal
Monitor-Visual Flats)

       The WF/PC-2 was used to make internal calibration visual flat images
as part of the Cycle 6 internal monitoring of the instrument's operations.
This proposal defines the standard series of internal flat fields, which
will be executed twice per month.  The observations were completed as
planned, and no anomalies were reported.

   1.14 Completed WF/PC-2 6699 (The Globular Cluster System of the Dwarf
Elliptical System Galaxies NGC-185 and NGC 205)

       The WF/PC-2 was used to make observations of the globular cluster
system around the nucleus of dwarf galaxy NGC-185.  The purpose is to
carryout a general reconnaissance of the properties of the globular
clusters.  The observations were completed as planned, and no anomalies
were reported.

   1.15 Completed Two Sets of STIS/MA2 7093 (Dark Measurement for MAMA Band
1, and Band 2)

       The Space Telescope Imaging Spectrograph (MA2) was used to make dark
calibration observations of the MAMA Band 1 and Band 2.  These observations
are to be used to establish that the detectors are performing nominally,
that no internal movement of the MCP has taken place, and to establish the
dark level in orbit for a given operating temperature.  The observations
were completed as planned, and no anomalies were reported.
