1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed Three Sets of WF/PC-2 5479 (Subarcsecond Structure in
       Nearby AGNs) 

       The WF/PC-2 was used to make snapshot observations of the nearby
       active galactic nuclei of ZW1408+137 to study the interactions
       between the central engine, the stars, and the interstellar matter
       in the AGN. The observations were executed as scheduled, and no
       anomalies were noted.

       planned, and no problems were reported. 

   1.3 Completed WF/PC-2 5369 (HST Medium-Deep Survey: Cycle 4 Medium, High
       Galactic  Latitude) 

       The WF/PC-2 made a series of observations of high latitude objects

       no problems were reported. 

   1.6 Completed WF/PC-2 5560 (WF/PC-2 Cycle 4 Calibration: Internal
       Monitor. 1) 

       The WF/PC-2 was used to make several internal bias, K-Spot, and flat
       calibration observations to monitor the CCD camera electronics, the
       optical alignment, and to check for contamination. The observations
       were completed as planned, and no anomalies were noted. 

   1.7 Completed WF/PC-2 5375 (High Resolution Images of Virgo Galaxies
       With Kinematically Distance Cores) 

       The WF/PC-2 was used to make observations of galaxy NGC-4550 which
       is located in the Virgo Cluster. The observations were completed as
       planned, and no anomalies were reported. 

   1.8 Completed Two Sets of WF/PC-2 5562 (WF/PC-2 Cycle 4 Calibration: 
       Internal Monitor 3: Darks)

       The WF/PC-2 was used to obtain several 30-minute long, dark
       exposures to provide ongoing calibration of the CCD dark current and
       to monitor and characterize the evolution of hot pixels. The
       observations were executed as scheduled, and no anomalies were
       noted. 

   1.9 Completed WF/PC-2 5352 (Gravitational Lensing Studies With HST: Dark
       Matter and High Redshift) 

       The WF/PC-2 was used to make deep image of the gravitationally lensed
       system ABELL2390. The main target is a set of giant arcs within the
       system. The observations were completed with no reported problems. 

   1.10 Completed WF/PC-2 5764 (WF/PC-2 Cycle 4 Calibration: Internal Flats 
       - Repeat)

       The WF/PC-2 was used to make observations of the low redshift quasar
       I13218+055 to study the morphology of the underlying galaxy. The
       observations were executed as scheduled, and no problems were
       reported. 

   1.12 Completed Two Sets of WF/PC-2 5446 (The Nuclei of Nearby S0 and 
       Spiral Galaxies: A PC Snapshot Imaging)

       The WF/PC-2 was used to make observations of the core region of
       galaxy NGC-4845 to provide statistics on the nuclear cusps, stellar
       condensations, and inner stellar disks and dust lanes. The
       observations were executed as scheduled, and no anomalies were
       noted. 

   1.13 Completed WF/PC-2 5710 (WF/PC observations of the Most Luminous 
       Galaxies in the Universe)

       The WF/PC-2 was used to make observations of IRAS10214 which is
       known to be one of the most luminous galaxies in the universe. The
       purpose of the observations is to determine the morphology of the
       galaxy and to find out if the galaxy is actually two colliding
       galaxies or a single forming galaxy. The observations were completed

   2.3 Significant HSTARs: None

   2.4 Operations Notes: 

       STGT operations continue to be nominal.

       The installation of flight software version 9.4 was successfully
       completed last night.  The purpose of this installation was to move
       the contents DF224 logical memory units 1 and 2 to shared memory. 
       This has two major benefits.  First, more of the flight software was
       moved to what should be more reliable memory units.  Second, in
       anticipation of more use of the coprocessor, the flight databases
       are now accessible by the coprocessor. The KING software, which
       provides only basic flight software functions, was utilized for this
       installation so the software could be moved without transferring to
       PSEA control.  Flight software still remains in LMU0 which is in the
       original Rockwell memory because this could not be moved to shared
       memory without going to PSEA control.
