1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed FOS/BL 3618 (Execution Processes for the Outer Planet UV 
       Emissions: Future - Cycle C)

       The Faint Object Spectrograph (Blue Side) was used to observe the
       planet Saturn to learn more about the processes responsible for the
       "electroglow" emission in the planet's upper atmosphere. Blind
       pointing was used to acquire the target and course track was used
       for guiding, since diffuse emission was being observed and the
       proposes want to avoid loss of lock. The observations were completed 
       in fine lock . Some of the observations could not be displayed due
       to power problems at Goddard Space Flight Center (See Note 2.4). The
       observations will be analyzed later from playback tapes. 

   1.2 Completed PC 4109 (WF/PC Cycle 2 Calibration: Rapid Internal Monitor)

       Rapid Internal Monitoring observations were made with both the Wide
       Field Camera and the Planetary Camera using filter F555W to look for
       new forms of contamination (i.e. daises and measles), and the
       possible return of quantum efficiency hysteresis. The observations
       were monitored in the OSS, and the data quality was assessed. No
       problems were reported. 

   1.3 Completed FOS/BL 4953 (QSO Absorption System Snapshot Survey - Part 3 
       of 3: cycle 3 High)

       The Faint Object Spectrograph was used to make one observation of
       quasar 2215-0347 to look for absorption lines at low redshift, and
       also emission lines in the QSO's continuum. The observation was
       executed as scheduled, and no problems were reported. The spectral 
       observations was reported to look good.

   1.4 Completed FOS RD 4396 (QSO Absorption System Snapshot Survey - Part 1 
       of 3: Cycle 3 High)

       The Faint Object Spectrograph (Red Side) was used to make two sets 
       of spectrographic observation of quasar 0100+0205 and 0117+2118 to
       look for absorption line systems at low red shift, emission lines,
       and to study the QSO's continuum. The first set of observations
       could not be monitored due to a power outage at GSFC. (See Note 2.4)
       Nevertheless, the observations were later analyzed and reported to
       look fine. The second set of observations were also reported to look
       fine. 

   1.5 Completed Two Sets of 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. A total of two observations were received. Both
       observations were reported to be saturated. 

   1.6 Completed Three Sets of PC 5014 (WF/PC Cycle 3 Calibration: PC Flats 
       Narrow. 2)

       The Planetary Camera was used to make two standard Earth
       calibrations images for flat fielding of PC observations. Medium and
       narrow filters were used, with and without neutral density filters.
       The observations were executed as scheduled. The first observation
       was partially saturated, and the second was completely saturated. 

   1.7 Completed FOC/96 4113 (Auroral Imaging of Jupiter with the FOC Cycle 
       2/ February-March 1993)

       The Faint Object Camera was used to make two images of the auroral
       emissions on the planet Jupiter at 1600 A0. Both north and south
       observations were contained within the sequence. The OSS verified
       that the correct filter was in place, but a rejected TDRSS contact
       prevented the OSS from uplinking a pointing correction until after
       the first observation had occurred. The first observation did not
       point at Jupiter. After the maneuver was completed, the subsequent
       observations were received and displayed. They were reported to be
       well centered, and to be well exposed. 

   1.8 Completed Two Set of FOC/96 4821 (MAGELLANIC Cloud Planetary Nebulae:
       Cycle 3 Med.) 

       The Faint Object Camera (f/96) was used to make one observation of
       the planetary nebulae LMC-N66 which is located in the Large
       Magellanic Cloud to determine its mass and age. The observations
       were executed as scheduled, and no problems were reported. 

   1.9 Completed Two Set of WFC 4849 (GTO High Latitude Parallel Program: 
       Cycle 3 High)

       The Wide Field Camera was used to make high latitude sky survey
       observations taken in parallel with the prime science observations.
       The observations were executed as planned, and no problems were
       reported. 

   1.10 Completed GHRS/2 4876 (Weak Interstellar Absorption Toward Zeta Orp - 
        Augmentation Cycle 3 High)

        The High Resolution Spectrograph was used to make observations of
        the star Zeta Oph (Visual Mag. of 2.56). This star has interstellar
        absorption lines, and was observed using the Echelle Mode
        spectrograph to obtain spectra fo the weak interstellar line of
        Silicon at 3235 A0. The OSS monitored the observations and assessed
        the data quality. No problems were reported. 

   1.11 Uplinked Updated Ephemeris Tables, Per MOSES 2871

   1.12 Completed GHRS/2 4272 (Supersonic Chromoshperic Winds  - Cycle 3 Med)

        The High Resolution Spectrograph was used to make observations of
        the star Alpha Aquari (Visual Mag. of 2.90) to learn more about the
        chromosphereic winds by looking at the fluxes, profiles, and shifts
        of several spectral lines which are produced in the transition
        region where the winds are accelerated. The observations were
        completed as scheduled, and no problems were reported. 

   1.13 Completed Two Sets of FOS/BL 3545 (The Evolution of the UV Spectra 
        in Early Type Galaxies Out to Z = 0.7)

        The Faint Object Spectrograph was used to make two sets of
        observations of the weak radio galaxy 53W022. These observations
        were executed in parallel with other science observations. Both
        sets of observations were received and displayed. No anomalies were
        noted. 

   1.14 Completed FOC/96 4969 (Search for QSOs Suitable for Subsequent 
        Observations of He II)

       The Faint Object Camera was used to make ultraviolet images of the
       quasi-stellar object 1333+2821 to measure the levels of its
       ultraviolet flux to see if this object is suitable for subsequent
       observation with the FOS and GHRS. They are looking for absorption
       features of Helium II at 304 A0. There was a failed FHST update
       prior to the observation, but the guide star acquisition did achieve
       fine lock on a star. (See Note 2.2) The subsequent observations
       showed no target. 

   1.15 Completed FOC/96 4804 (UV Imaging of Nearby Galaxies with the FOC/96)

       The Faint Object Camera was used to complete one snapshot ultraviolet
       observation of the nearby galaxy UGC-11012 The exposures lasted for
       ten minutes and used filter F220W. The observations was reported to
       look fine.

   2.3 Significant HSTARs: None

   2.4 Operations Note: 

       A major power outage occurred on Friday 190/1511Z in the Building
       3/14 area when electrical power was switched for commercial power to
       diesel power. The power outage was building wide. The equipment
       automatically switched over to the backup UPS System, and ran on
       batteries for about 20 minutes, until the batteries ran out. The
       power outage lasted for about 1 hour 19 minutes. Two periods of 26
       minutes 21 seconds, and 6 minutes 5 seconds of real-time telemetry
       were lost and are unrecoverable.
