PERIOD COVERED:  0000Z (UTC) 03/19/97 - 0000Z (UTC) 03/20/97

Daily Status Report as of 079/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed WF/PC-2 6361 (High Resolution Imaging of X-Ray Selected =
AGNs)

       The WF/PC-2 was used to make high resolution  observations of the =
known low, red-shifted x-ray active, galactic nucleus (AGN) MS1455.7+2.  =
These data will allow a study of the optical properties of an unbiased =
sample of AGN host galaxies.  The observations were completed as =
scheduled, and no problems were reported.

   1.2 Completed FGS 6538 (The Distances to Dwarf Novae, and the =
Calibration of the Technique of Infrared Spectroscopic Parallax)

       The FGSs were used to make astrometric observations of the dwarf =
novae SS-Aug and several other reference stars in order to measure its =
distance from its parallax.  The distances to this dwarf novae is poorly =
known.  This deficiency severely impacts our ability to quantify the =
energetics of the various processes taking place in dwarf novae systems.  =
The observations were executed as scheduled, and no anomalies were noted. =


   1.3 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 QDOTURIL02. 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.

   1.4 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 HD48915A 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. 

   1.5 Completed NIC/UPLI 7041 (NICMOS Coarse Optical Alignment)

       The NIC/1 was used to make observations of the cluster NGC-3603 in =
order to completed coarse optical alignment of the system.  The purpose =
of this activity is to perform a series of iterative adjustments of the =
NICMOS pupil alignment mechanism to establish the initial optical =
alignment in focus and tilt for its cameras.  The observations were =
completed as planned, and no anomalies were reported. 

   1.6 Completed NIC1 7135 (NICMOS Intermediate  Focus / Alignment)

       The NICMOS was used to make observations of NGC-3603.  The purpose =
of this activity is to perform a series of iterative adjustments of the =
NICMOS pupil alignment mechanism to establish the initial optical alignmen=
t in focus and tilt for all three cameras.  The observations were =
completed as schedule, and no anomalies were reported.
