1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed WF/PC-2 5090 (Large Area/Multicolor Survey: Cycle 4)

       The WF/PC-2 was used to make deep exposure images of field #1416 as  
       part of a large area, high galactic latitude, multicolor sky survey
       to learn more about the distribution of galaxies, their morphology,
       distribution in magnitude and redshift, and evolution of galactic
       luminosity, function, and colors. A total of 20 observations were
       received and displayed. They were reported to be okay, except for an
       occasional recentering event. 

   1.2 Completed WF/PC-2 5397 (Determination of the Extragalactic Distance 
       Scale: Cycle 4 High)

       The WF/PC-2 was used to make images of galaxy NGC-5457-FL to help
       establish the Hubble constant to an accuracy of better than 10% by
       measuring the periods of Cepheid variable stars within the galaxy.
       Five observations were executed without apparent problems, except
       for recenterings which occurred during each exposure. Complete
       analysis is pending receipt of the observations from the science
       tape recorder. 

   1.3 Completed GHRS/2 5547 (GHRS/Side 2 Detector Calibrations: Cycle 4) 

       The High Resolution Spectrograph (Side Two) was used to make dark
       and internal flat calibration observations to check the stability of
       the detectors. There was no external target used. Eleven
       observations were executed without appearent problems. Complete
       analysis is pending receipt of the observations from the science
       tape recorder. 

   1.4 Completed GHRS/2 5600 (GHRS Side 2 Wavelength Monitor (1st Order 
       Gratings): Cycle 4)

       The High Resolution Spectrograph (Side Two) was used to make
       wavelength and resolution calibration observations of its first
       order gratings using the internal calibration lamp. Three
       observations were monitored, and seemed to go okay. Two observations
       occurred during LOS, and will be analyzed later. 

   1.5 Completed WF/PC-2 5476 (Continuum Snapshots of the 3CR Radio
       Galaxies) 

       The WF/PC-2 was used to make snapshot images of radio galaxy 
       3C66.0B as part of a continuum survey and to study the galaxy's
       morphology. The observations were executed as scheduled, and no
       anomalies were noted. 

   1.6 Completed WF/PC-2 5303 (Calibration of Stellar Evolutionary Ages and 
       Variations in the IMF)

       The WF/PC-2 was used to make observations of open cluster NGC-2477
       to determine the luminosity function of the white dwarfs (WD) and
       low mass (i.e., red) stars. The OSS monitored the observations, and
       assessed the data quality. No anomalies were noted.
