1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed GHRS/2 3584 (Probing the Voids)

       The High Resolution Spectrograph was used to make observations of
       the active galactic nuclei of Markarian galaxy IZWI which is located
       behind an extra-galactic void. This is to study the nature,
       abundance, and distribution of Hydrogen I absorbing clouds. The
       on-board target acquisition was successful. Most of the observations
       were reported to look okay. 

   1.2 Uplinked Updated Ephemeris Tables, Per MOSES 2871

   1.3 Completed WFC 5013 (WF/PC Cycle 3 Calibration: WFC Flats Narrow. 2)


       The Wide Field Camera was used to make Earth flat calibration images
       to be used for flat fielding of WFC observations. The observations
       used the narrow band filters, both with and without neutral density
       filters. The images were received and reported to look okay. 

   1.4 Completed FOC/96 4153 (FOC UV Throughput Monitoring)

       The Faint Object Camera was used to make observations of the
       ultraviolet standard star BPM16274 to help determine the ultraviolet
       throughput of the HST-FOC. The observations were executed as
       scheduled, and no problems were reported . 

   1.5 Completed FOS/BL 5053 (Cycle 2 FOS Location of Spectra: Y-Base Maps)


       The Faint Object Spectrograph (Blue Side) was used to make a Y-Base
       calibration test, spectra of the internal Pt-Ne lamps looking
       through the 0.3 arc-second apertures for every grating. These
       observations mapped the face of the photocathod using 24 Y-steps and
       1 X-step. The observations were monitored in the OSS, and the data
       quality was assessed. No problems were reported.
