1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

 read 13  1.1 Completed FOS/BL 3791 (Quasar Absorption Line Survey)

       The Faint Object Spectrograph (Red Side) attempted to make
       observations of quasar PKS1302-10. The baseline guide star
       acquisition failed. All seven observations were reported as having
       failed. (See Operations Note 2.4) 

   1.2 Completed Two Sets of FOC/96 4107 (Search QSOs Suitable for
       Subsequent Observations) 

       The Faint Object Camera attempted to make two separate observations
       of quasar 1320-106. Both baseline guide star acquisitions failed
       after FGS #2 electronics had been turned off. The shutter never
       opened for either observation. (See Operations Note 2.4) 

   1.3 Completed FOC/96 3504 (High Spatial Resolution Imaging and Spatial of 
       Active Galactic Nuclei)

       The Faint Object Camera was used to attempt to make observations of
       active galactic nuclei 3C277.3 . The base line guide star
       acquisition failed because the FGS #2 electronics had been turned
       off. The shutter never opened. 

   1.4 Completed WFC 1297 (GTO High Latitude Parallel Program)

       The Wide Field Camera attempted to make two images which were to
       have been taken in parallel with the prime science observations.
       However, the baseline guide star acquisition on the prime science
       observation failed, due to the FGS #2 electronic having been turned
       off. The shutter never opened. (See Operations Note 2.4) 

   1.5 Completed Two Sets of FGS 3688 (Diagnostic of Early Stellar 
       Evolution)

       Two sets of observations were scheduled using the FGS to
       make astrometric observations of pre-main sequence star 100628.
       These astrometric observations did not occur, because the guide star
       acquisition failed due to the ongoing problems with FGS #2. (See
       Operations Note 2.4 ) 

   1.6 Uplinked Updated Ephemeris Tables, Per MOSES 2871

   1.7 Completed WFC-PC 4109 (Rapid Internal Monitor)

       Both the Wide Field Camera and the Planetary Camera were used to
       make two internal flat observations using filter F555W to check for
       new forms of contamination (i.e., Daisies and measles). Both
       observations were received and displayed. The two internal flats
       were reported to look normal. 

   1.8 Completed GHRS/2 3755 (Absorption Cross Sections of Nearby Galaxies)

       The High Resolution Spectrograph was used to attempt to make
       observations of quasar 1543+489 to study the absorption lines
       produced by nearby galaxies. The science observations were not
       executed due to the problems with FGS #2. The wavelenght calibration
       was also not taken. 

   1.9 Completed FOS/RD 4059 (Absolute Photometric Monitor)

       The Faint Object Spectrograph was used to make eight observations of
       standard star HZ-44 to help determine the absolute sensitivity of
       the FOS detectors. These observations will be used for pipeline data
       calibrations. All eight observations were received and displayed.
       The guide star acquisitions did no occur. The spectral observations
       contained some light, the target was reported to not be properly
       centered. 

   1.10 Completed Three Sets of PC 3603 (Snapshot of Protoplanetary Nebulae)

       The Planetary Camera was used to make three sets of observations of
       the protoplanetary nebula CPD-64D293. The first observations did
       occur in spite of the fact that the guide star acquisition did not
       occur. (See operations Note 2.4) Its image was smeared. Of the
       remaining subsequent images; one showed a faint stellar object, one
       looked normal, and three were reported to be blank. 

   1.11 Completed GHRS/2 2537 (Physical Conditions of Interstellar Gas)

       The High Resolution Spectrograph was used to attempt to obtain high
       signal to noise spectra of star HD80007. The deflection calibration
       observation occurred. The remaining four science observations did
       not occur because of problems using FGS #2. (See Operations Note 2.4) 

   1.12 Completed PC 4249 (Black Holes Stellar Dynamics and Populations)

       The Planetary Camera was used to take two observations of the inner
       core region of the elliptical galaxy NGC-4623 which is located in
       the Virgo Cluster. Both observations failed because the FGS #2 was
       turned off. The shutter toggled open for 0.11 seconds, but nothing
       was noticed in the field of view. 

   1.13 Completed GHRS/2 4065 (Dark Noise Monitoring)

       The High Resolution Spectrograph was used to make one internal dark
       calibration observation. The observations was received and displayed
       in the OSS. It was reported to look normal. 

   1.14 Completed FOS/RD 4698 (FOS Dark Monitoring)

       The Faint Object Spectrograph was used on both the red and blue
       sides to obtain ten dark exposures to determine the instruments
       background calibration. All ten observations were received and
       displayed. All ten were reported to look normal. 

   1.16 Initiate GHRS/2 4766 (Boron in Population II Dwarfs, Part 2)

       The High resolution Spectrograph was used to initiate spectral
       observations of the Boron I lines in the metal poor unevolved star
       HD140283. The OSS monitored the spiral search portion of the onboard
       target acquisition. The target was found in the first map. The
       observations are currently ongoing, and will be analyzed later.

   2.3 Significant HSTARs: None

   2.4 Operations Note:

       FGS #2 has shown an anomalous behavior where it intermittently fails
       to move to certain positions. The problem is yet undetermined, and
       data continues to be analyzed at this time. A special operations
       request executed to shut down FGS #2 at 043/1435Z. This will make
       the unit thermally stable, but will not allow it to accept normal
       operational commanding. The STScI is regenerating SMSs to restrict
       FGS #2 usage.
