PERIOD COVERED:  0700 EST
Daily Status Report as of 160/1200Z.

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed WF/PC-2 5570 (Cycle 4 Calibration: Earthflats, Large Set)

       The WF/PC-2 was used to make a set of Earth flat calibration images
       using different filters in order to construct high quality flat
       fields of the OTA illumination pattern. A total of eight images were
       received and displayed. Three were reported to be underexposed, and
       the others were okay. 

   1.2 Completed WF/PC-2 5476 (Continuum Snapshot of 3CR Radio Galaxies)

       The WF/PC-2 was used to make snapshot images of radio galaxy 3C207.0
       as part of a continuum survey and to study the galaxy's morphology.
       All of the images were received and displayed. They were reported to
       look okay. 

   1.3 Completed FOS/BL 5500 (Energy Balance and Emission Lines in DQ
       Herculis Type Stars: Cycle 4 Medium) 

       The Faint Object Spectrograph (Blue Side) was used to make
       ultraviolet spectral observations of the eruptive binary star YY
       Draconis. The observations executed, and was stored on the Science
       Tape Recorder #1. After the tape playback, it was reported that
       seven observations were received, and they looked okay. More data
       still remains on Science tape Recorder #3. (See Operations Note 2.1) 

   1.4 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
       as part of a medium deep sky survey. The observations were taken in
       parallel with other prime science observations. The first four
       observations were played back from Science Tape Recorder, and they
       were reported to look okay. More data still remains on Science
       Tape Recorder #3, and will be analyzed later. (See Operations Note
       2.1) 

   1.5 Completed WF/PC-2 5655 (WF/PC-2 Cycle 4 Calibration: Internal 
       Monitor. 2 Flats Part 2)

       The WF/PC-2 was used to make ultraviolet flats. Two images were
       received and displayed. No anomalies were noted. 

   1.6 Completed WF/PC-2 5446 (The Nuclei of Nearby S0 and Spiral Galaxies)

       The WF/PC-2 was used to make observations of galaxy NGC-3184. The
       observations were executed as scheduled, and the science data
       remains of Science Tape Recorder #3. It will be analyzed later. No
       anomalies were noted. 

   1.7 Completed FOS/BL 5438 (Io's Atmosphere: UV Spectroscopy of Neutral 
       Components)

       The Faint Object Spectrograph (Blue Side) was used to make far
       ultraviolet spectrographic observations of Jupiter's moon Io. The
       first observations was received in real-time. The OSS computed and
       successfully uplinked a corrective pointing maneuver. No anomalies
       were noted. 

   1.8 Completed WF/PC-2 5397 (Determination of the Extragalactic Distance 
       Scale: Cycle 4 High)

       The WF/PC-2 was used to make images of galaxy NGC-4535 to be used in
       measuring the periods of Cepheid variable stars within the galaxy.
       The observations were executed as scheduled, and no anomalies were
       noted. 

2.0 FLIGHT OPERATIONS SUMMARY:

    2.1 Guide Star Acquisitions: 


                            Scheduled Acquisitions : 5
                                        Successful : 5
                          Scheduled Reacquisitions : 10
                                        Successful : 10

       At 160/0251 the reacquisition attained fine lock. However, the star
       presence was lost near the end of a sequential update. The Take Data
       Flag (TDF) did not go up, and the shutter did not open for
       subsequent FOS observations. 

   2.2 FHST Updates: 

                              Scheduled :12
                             Successful :12

   2.3 Significant HSTARs: None

   2.4 Operations Notes: 

       There were no outstanding problems onboard the HST during the
       previous operational day. 

3.0 ANOMALY STATUS:

   4.1 Significant New Anomalies: None

   4.2 Significant Unresolved Anomalies: None

4.0 SIGNIFICANT FORTHCOMING EVENTS: 

       Nothing at this time.
