1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed FOS/BL 4222 (Mass Exchange Binaries- Cycle 1, Final Piece)

       The Faint Object Spectrograph (Blue Side) was used to make two
       spectral observations of the binary star system HZ Herculis. This
       system has a normal star as the central star, with a compact
       secondary companion. The first observations was received and
       displayed. It was reported to have an overlight sum 43,000. The
       second observation was lost because it completely filled the science
       tape recorder and the required down-link between the first and
       second observation was not available. As a result the science tape
       recorder was rewound to make room for the second observation, which
       was received and displayed. The OSS had data receipt problems, but
       was able to display the observation. It was reported to look okay. A
       line outage recorder playback was requested. 

   1.2 Completed WFC 1297 (GTO High Latitude Parallel Program)

       The Wide Field Camera was used to make two high latitude
       observations which were taken in parallel with the prime science
       observations. Both observations were received and displayed in the
       OSS. They were reported to look okay. 

   1.3 Completed WFC 4658 (Determination of the Extragalactic Distance 
       Scale, M101)

       The Wide Field Camera was used to make two observations of galaxy
       M-101 which is located in Ursa Major. This is to attempt to discover
       new Cepheid variable stars. Both observations were executed in
       course track, with no apparent problems in the telemetry. The data
       was received and displayed, and both observations were reported to
       look okay. 

   1.4 Completed PC 3603 (Snapshot  of Protoplanetary Nebulae)

       The Planetary Camera was used to attempt to make one observation of
       the protoplanetary system PK043+11D1. The observation was scheduled
       to be executed in fine lock. A bad V3 observer bias, left over from
       the high drift V3 drift rate prior just prior to the previous earth
       occultation, caused the guide star acquisition to fail fine lock.
       It did, however, obtain course lock. Just after the day/night
       transition, there was a big glitch in the V3 bias, but the lock
       held. Data was received and displayed in the OSS. The target was
       reported to be smeared as a result of the V3 jitter. 

   1.5 Completed FOC/96 4804 (UV Imaging of Nearby Galaxies With FOC/96)

       The Faint Object Camera was used to make one ten minute ultraviolet
       snapshot exposure of nearby galaxy UGC-5398 using filter F220W. The
       observations was executed in course track. A slow roll was observed
       in the V1 observer bias during the observation. The image still
       remains on the science tape recorder, and will be analyzed later. 

   1.6 Completed GHRS/2 4066 (GHRS Echelle Spectral Lamp Mini-Functional 
       Test)

       The Echelle spectral lamp Mini-Fuction Test was completed as an
       internal test and calibration of the High Resolution Spectrograph.
       The first part of the test was received in real-time, and the second
       part was during LOS. The OSS expressed concerns about the lamp
       assembly temperature going out of limit, by being left on too long.
       It was monitored closely. 

   1.7 Completed PC 4140 (WF/PC Cycle 2 Calibration: Rapid Internal Monitor 
       Part 2)

       The Planetary Camera was used to make internal flat observations
       which will be used to look for new forms of contamination (i.e.,
       daises and measles), and the return of quantum efficiency
       hysteresis. The observations complete as scheduled, and no problems
       were reported.
