PERIOD COVERED:  0000Z (UTC) 05/13/97 - 0000Z (UTC) 05/14/97

Daily Status Report as of 134/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed NIC/2 7154 (NICMOS Coronographic Hole Monitor)

       The Near Infrared Camera (NIC Camera Two) was used to make
observations of object NGC-3603 in order to monitor the effects of
coronagrapghic hole.  The purpose of this proposal is to take lamp flats
with camera Two (and cameras One and Three occasionally) to monitor the
location of the coronographic spot.  The observations were completed as
scheduled, and no anomalies were reported.

   1.2 Completed Two Sets of NIC/1/2/3 7043 (NICMOS Focus Monitor)

       The Near Infrared Cameras (Cameras One, Two and Three) were used to
make observations of NGC-3603 in order to make focus calibration and
monitoring measurements.  This proposal is built to run NIC/1/2 focus
sweeps on a weekly
basis, and NIC/3 focus sweeps twice a week during SMOV.  The observations
were executed as scheduled, and no anomalies were noted.

   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 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.

   1.5 Completed WF/PC-2 5901 (Imaging of Gravitational Microlens Source
Systems and Their Underlying Stellar Backgrounds)

       The WF/PC-2 was used to make observations of the gravitation
microlens source system LMC-0534-7 which is located in the Large Magellanic
Cloud.  This is to study the underlying stellar background.  The deep
images of the sources will provide first epoch images for comparison with
later images to resolve the proper motion of the lensing object, if it is
luminous.  The observations were executed as scheduled, and no anomalies
were noted.

   1.6 Completed WF/PC-2 6346 (Snapshot Survey of the Ultraluminous IRAS
Galaxy Sample-Part 1 High)

       The WF/PC-2 was used to make snapshot survey observations of the
ultraluminous IRAS galaxy CL-ULIR010.  These data will be searched for
multiple cores, which imply a merger has occurred, and for starburst
regions.  The observations were executed as scheduled, and no anomalies
were noted.

   1.7 Completed WF/PC-2 6713 (Geometric Measurement of Galaxy Distance)

       The WF/PC-2 was used to make observations of supernova remnant
SN1926B in order to make a distance calibration for the galaxy in which it
is located.  The supernova is being used as a powerful new geometric method
for the determination of a galaxy's distance, by obtaining high spatial
resolution imageing polarization of the candidate supernova light echoes.
The observations were completed as planned, and no anomalies were reported.

   1.8 Completed Four Sets of WF/PC-2 7202 (The WF/PC-2 B Band Parallel
Survey: A Systematic and Synoptic Study of Galaxy Formation and Evolution -
Short Orbit Case)

       The WF/PC-2 was used to make observations as part of a B-Band Survey
to make a synoptic study of galaxy formation and evolution.  These
observations were taken in parallel with the prime science observations.
They were completed as planned, and no anomalies were reported.

   1.9 Completed Four Sets of NIC/1/2/3 7048 (NICMOS Parallel Thermal
Background Test)

       The Near Infrared Cameras (Cameras One, Two and Three) were used to
make observations of an object designated as Target-1 in order execute
measurements of the stability of the HST thermal emissions.  The
observations were executed as scheduled, and no problems were reported.

   1.10 Completed Two Sets of WF/PC-2 6363 (The Environments and Host
Galaxies of BL-Lac Objects)

       The WF/PC-2 was used to make snapshot survey observations of BL-Lac
objects MS2143.4+0 in order to study their environment and their host
galaxies.  The goal is to investigate systematic trends in host galaxy
type, unusual morphological features, nearby companion galaxies, etc.  The
observations were executed as scheduled, and no anomalies were noted.
