1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

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

       The WF/PC-2 made a series of observations of high latitude objects
       as part of a medium deep sky survey. The observations were taken in 
       parallel with other prime science observations. The observations were 
       completed as scheduled, and no anomalies were noted.

   1.2 Completed WF/PC-2 5778 (Cycle 4 Lyman Alpha Throughput Verification)

       The WF/PC-2 was used to make ultraviolet observations of standard
       star BD+75D325 through filter F130LP as part of a Lyman Alpha
       throughput verification test. The observations were completed as
       scheduled, and no anomalies were reported. 

   1.3 Completed WF/PC-2 5354 (Imaging in the Crab Nebula)

       The WF/PC-2 was used to make images of NGC-1952-BR (aka, M-1, the
       Crab Nebula) to study ionization structure and to look for hot
       spots. The observations were completed as planned, and no problems
       were reported. 

   1.4 Completed WF/PC-2 5560 (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. 

   1.5 Completed FGS 5135 (Extragalactic Astrometry and Astrophysics)

       The FGSs were used to make astrometric observations to obtain data
       needed to measure the HIPPARCOS reference frame with respect to the
       extragalactic reference frame. The observations were executed as 
       scheduled, and no anomalies were noted. 

   1.6 Completed WF/PC-2 5091 (GTO High Latitude Parallel Program - Cycle 4)

       The WF/PC-2 was used in parallel with the prime science observations
       to make high galactic latitude observations greater than +/-30
       degrees. The observations were executed as scheduled, and no
       problems were reported. 

   1.7 Completed WF/PC-2 5446 (The Nuclei of Nearby SO and Spiral Galaxies:
       A PC Snapshot Imaging Survey)

       The WF/PC-2 was used to make observations of the core region of
       galaxy NGC-1527 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. 

   1.8 Completed FOS/BL 5711 (Black Hole Binaries in the LMC)

       The Faint Object Spectrograph (Blue Side) was used to study the LMC
       binary CAL 87, which is the known eclipsing black hole candidate.
       The changes in the continuum will be compared with model predictions
       to learn more about the accretion disk.  The proposal completed with
       no reported anomalies.

   1.9 Completed WF/PC-2 5523 (Post-COSTAR FOC/96 Fine Aperture Location)

       The WF/PC-2 was used to refine the location of the f/96 aperture in
       the V2-V3 coordinate frame.  There were no reported problems during 
       this observation.

   1.10 Completed WF/PC-2 5092 (GTO Low Latitude Parallel Program - Cycle
       4) 

       The WF/PC-2 was used to make observations taken in parallel with the
       prime science observations. This is part of a survey to take
       pictures of a large number of fields within 30 degrees of the
       galactic plane. The observations were completed as planned, and no
       problems were reported. A second set of planned observations were
       lost because of the Safemode entry due to SADE Failure Flag Test at
       008/0820Z. (See Note 2.4) 

   1.11 Completed WF/PC-2 5629 (Cycle 4 Photometric Calibration Monitor 1C:
       4-Chip Standard in F170W)

       The WF/PC-2 was used to make photometric calibration observations of
       the ultraviolet standard star GRW+70D582. The observations were
       executed as scheduled, and no anomalies were noted. 

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

       The WF/PC-2 was used to make internal flat calibration images using
       the VIS lamp and internal sources. The observations were executed as
       scheduled, and no anomalies were noted. A second set of planned
       observations were lost because of the Safemode entry due to SADE
       Failure Flag Test at 008/0820Z. (See Note 2.4) 


   1.13 Completed FOS/RD 5753 (SINS: The Supernova Intensive Study) 

       This proposal is part of a continuing project to study the 
       development of supernovae and their circumstellar matter.  In this
       case, LMC-SN1987 was observed.  The observation completed normally,
       and there were no reported problems.

   1.14 Completed WF/PC-2 5584 (Parallel High Resolution Imaging of Diffuse
        Objects in the Magellanic Cloud) 

       The WF/PC-2 was used to observe diffuse object LMC-30DOR.  Of 
       particular interest were H II regions, planetary nebulae, snares, 
       supershells, and proto-stellar and maser regions. The observations
       were not completed as planned. 

      *** Safemode entry due to SADE Failure Flag Test at
       008/0820Z. (See Note 2.4)

   2.3 Significant HSTARs: 

       HSTAR 5084: Safemode entry due to SADE Failure Flag Test at
       008/082054Z. (See Note 2.4) Science recovery SMS will start at 
       010/1200Z.

   2.4 Operations Notes: 

       The HST entered software sun point safemode at 008/082054Z due to
       the failure of the SADE torque failure test. The SADE 1 R unit was 
       switched off and SADE 2 turned on by the flight software when the
       problem was experienced. A health and safety load was uplinked at
       008/1744Z, and was for the interval 008/1832Z - 010/0030Z. Another
       health and safety load has been prepared for the interval 010/0030Z
       - 010/1200Z. 

       A revised SMS that incorporates certain solar position restrictions
       has been generated and is to begin execution on Tuesday, Jan. 10 at
       7:00 A.M. local. These restrictions are temporary safety measures to
       enable return to science operations while analysis of the SADE 1 R
       failure continues. 

       The spacecraft onboard safing configurations have been modified to
       use the SADE 2 in the event of another safemode entry.

       Safemode Recovery Status meetings and telecons with ESA are being 
       held today (Monday). 

       Apart from the safing event, ESTR #2 experienced further bit slips. 
       A re-dump produced bit slips, but at different locations. 

3.0 ANOMALY STATUS:

   3.2 Significant Unresolved Anomalies: None

4.0 SIGNIFICANT FORTHCOMING EVENTS:
