PERIOD COVERED:  0000Z (UTC) 04/23/96 - 0000Z (UTC) 04/24/96

Daily Status Report as of 115/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed Four Sets of WF/PC-2 6188 (WF/PC-2 Cycle 5 Calibration: =
Dark)

       The WF/PC-2 was used to make internal dark calibration images.  =
The observations were completed as scheduled, and no problems were =
reported.

   1.2 Completed FOS/RD 6025 (Consequences of the Shoemaker-Levy Impact =
With Jupiter)

       The Faint Object Spectrograph (Red Side) was used to make =
spectrographic observations of the planet Jupiter in order to study the =
consequences from the impact of the comet Shoemaker-Levy.  This is to =
study the atmosphere following the impact to measure the chemical =
abundances as a function of time.  The observations were completed as =
scheduled, and no problems were reported.

   1.3 Completed Two Sets of WF/PC-2 6365 (A Snapshot Survey For =
Companions and Clusters around Wolf-Rayet Stars)

       The WF/PC-2 was used to make snapshot observations of Wolf-Rayet =
stars WR85 and WR148 in order to look for companion stars and clusters.  =
Photometry was performed on the Wolf-Rayet stars and associated stars.  =
The observations were completed as planned, and no anomalies were =
reported.

   1.4 Completed WF/PC-2 6835 (The Detail Morphology of Post-Merger =
Galaxies)

       The WF/PC-2 was used to make observations of the post-merger =
galaxy GAL-0158-4 in order to study its morphology.  This galaxy has =
little or no on-going star formation and a significant population of =
young stars.  The observations were executed as scheduled, and no =
anomalies were noted.

   1.5 Completed FOC/96 5835 (The Structure of the Inner Coma of the =
Comet Chiron)

       The Faint Object Camera (f/96) was used to make observations of =
the object/comet 2060 Chiron in order to study its inner coma.  The goals =
are to map the structure and color of the inner coma.  The observations =
were executed as planned, and no problems were reported.

   1.6 Completed WF/PC-2 6250 (WF/PC-2 Cycle 5 Calibration: Internal =
Monitor)

       The WF/PC-2 was used to make a series on internal calibration =
observations.  Internal flats, biases, and K-Spot calibration images were =
taken.  These observations are designed to monitor the health of the =
cameras.  The observations were executed as scheduled, and no anomalies =
were noted.

   1.7 Completed WF/PC-2 6187 (WF/PC-2 Cycle 5 Calibration: Earth Flat)

       The WF/PC-2 was used to make Earth streak flat calibration images. =
 These streak flats will be used to produce flat fields, to map the OTA =
illumination pattern and, in combination with other data, to produce new =
superflats.  The observations were completed as planned, and no problems =
were reported.

   1.8 Completed WF/PC-2 6363 (The Environments and Host Galaxies of =
BL-Lac Objects)

       The WF/PC-2 was used to make snapshot survey observations of =
BL-Lac object MS0607.9+7 in order to study its environment and its host =
galaxy.  The goal is to investigate systematic trends in host galaxy =
type, unusual morphological features, nearby companion galaxies, etc.  =
The observations were executed as scheduled, and no anomalies were noted.

   1.9 Completed FOS/BL 6202 (Cycle 5 FOS Spectral Flat field =
Calibration)

       The Faint Object Spectrograph (Blue Side) was used to make =
observations of the relatively featureless white dwarf star WD0501+527 in =
order to make flat field calibration images.  The observations were made =
through the 1.0 aperture, with all usable detector/disperser =
combinations.  The observations were executed as schedule, and no =
anomalies were noted.

2.0 FLIGHT OPERATIONS SUMMARY:

   2.1 Guide Star Acquisitions: 

                            Scheduled Acquisitions : 6
                                        Successful : 6

                          Scheduled Reacquisitions : 11
                                        Successful : 11

   2.2 FHST Updates: 

                              Scheduled : 15
                             Successful : 15

   2.3 Operations Notes: 

       Preparations were begun for the transfer of operations to the SAMS =
backup facility to allow for LAN work to proceed in the MOR area.  =
However, the MVIP graphics pages did not transfer electronically and the =
shift supervisor elected not to make the move as scheduled.

3.0 SIGNIFICANT FORTHCOMING EVENTS: 

        Nothing at this time.
