PERIOD COVERED:  0000Z (UTC) 04/22/97 - 0000Z (UTC) 04/23/97

Daily Status Report as of 113/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed Four Sets of FGS 7024 (FGS 3 Delta Mini-OFAD Post-SM2 =
Calibration)

       FGS #3 was used to make astrometric observations of stars OF51, =
OF63, OF89, OF91 and numerous other reference stars in order to reform a =
mini-OFAD Post-SM2 calibration.  The purpose of this activity is to =
calibrate the changes to the optical field angle distortions of FGS unit =
#3 that resulted from the servicing mission.  The observations were =
executed as scheduled, and no anomalies were noted. 

   1.2 Completed Five 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 NIC/3 7055 (NICMOS GRISM Validation)

       The Near Infrared Camera #3 was used to make observations of the =
object G191-B2B in order to perform validation of the operations of the =
three NICMOS grisms and supply the initial level of calibration for =
spectroscopic observations.  The observations were completed as planned =
and no problems were reported. 

   1.4 Completed FGS 7025 (FGS/FGS Alignment Post-SM2 Calibration =
(FGS1R))

       The FGSs were used to make observations of the astrometric field =
NGC-5617, and several other reference stars in order to work on the =
FGS/FGS alignment during the post-SM-2 period calibration.  These =
observations were completed as scheduled, and no problems were reported. 

   1.5 Completed NIC/1/2 7043 (NICMOS Focus Monitor)

       The Near Infrared Cameras (Cameras 1, and 2) 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 during SMOV.  The observations were executed as scheduled, and no =
anomalies were noted.

   2.3 Operations Notes: 

       There were no significant operational problems reported.

       The battery #2 capacity test is still being executed.

       The STIS CCD detector was turned off at 112/2233Z.
