   1.1 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 observations
       were completed as scheduled, and no anomalies were noted.

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

       The WF/PC-2 was used to make snapshot images of radio galaxies
       3C456.0, 3C141.0, and 3C454.1 as part of a continuum survey and to
       study the galaxies' morphology. The observations were executed as
       scheduled, and no anomalies were noted.

   1.3 Completed Three Sets of GHRS/2 5168 (Io Proton Aurora? : Cycle 4
       Medium)

       The High Resolution Spectrograph (Side Two) was used to make
       observations of Jupiter's moon Io while it is immersed in the plasma
       torus. The objective is to search for Lyman-Alpha emissions
       caused by protons trapped in Jupiter's magnetosphere, and
       interacting with Io. The observations were executed as scheduled,
       and no anomalies were noted.

   1.4 Completed WF/PC-2 5629 (WF/PC-2 Cycle 4 Photometric Calibration
       Monitor 1C: 4-Chip STD 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.

   1.5 Completed FOS/RD 5679 (Soft X-Ray Transient: Outbursts in Black Hole
       Accretion Disks)

       The Faint Object Spectrograph (Red Side) was used in the Rapid Mode
       to make spectral observations of the soft X-Ray transient GROJ422+32
       (aka, Nova Persei 1992). Emission lines will be used to learn more
       about the inner regions of the accretion disk. The observations were
       completed as planned, and 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 Three Sets of WF/PC-2 5568 (WF/PC-2 Cycle 4 Calibration:
       Decon)

       The WF/PC-2 was used to make an internal flat field calibration
       observation using the VIS lamp and the internal source as part of a
       decontamination operation. The observations were completed as
       planned, and no problems were reported.

   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-925 to be used in
       measuring the periods of Cepheid variable stars within the galaxy.
       The guide star acquisition for this observations failed to achieve
       fine lock. It was instead taken with coarse track guidance. No other
       anomalies were noted.

   1.9 Completed GHRS/1 5478 (Time-Resolved UV and X-Ray Spectrometry of
       X-Ray Binaries: Cycle 4 Medium)

       The High Resolution spectrograph was used to make RAPID Mode
       observations of the X-Ray binary system Her-X-1, which has an
       orbital period of 1.7 days. They are hoping to find the profile of
       the N V emission lines. The baseline guide star acquisition for this
       series of observations (a total of thirteen) failed completely. The
       guide star reacquisition for these observations managed to achieve
       coarse track.

   1.10 Completed FGS 5316 (Masses of Pre-Main Sequence Stars: Cycle 4
        Medium)

       The Fine Guidance Sensors were used in the TRANS Mode to make
       astrometric observations of the pre-main sequence binary star
       ELLAS-12 in the Taurus star forming region. The FGS data will
       provide the apparent orbits. The observations were executed as
       scheduled, and no anomalies were noted.

   1.11 Completed WF/PC-2 5569 (WF/PC-2 Cycle 4 Calibration: Internal 
Flats)

       The WF/PC-2 was used to make flat field calibration images with the
       VIS lamp, and the internal source. The observations were completed
       as planned, and no problems were reported.

       problems were reported.

   1.13 Completed 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 MARK79, MARK6, NGC-5929, MARK493 to study
       the interactions between the central engine, the stars, and the
       interstellar matter in these AGNs. The observations were executed as
       scheduled. There were two reported recentering events, for a total
       of eight seconds. No other amoalies were noted.

   1.14 Completed FGS 5657 (Duplicity Among Hyades Stars: Cycle 4 High)

       The FGSs (TRANS-Mode) were used to make astrometric observations of

       galactic nuclei. The observations were completed as planned, and no
       problems were reported.

   1.18 Completed WF/PC-2 5494 (Stellar Winds of Massive Stars in Nearby
       Galaxies)

                            Scheduled Acquisitions : 20
                                        Successful : 19

                            Primary Acquisition failure at 239/0126Z due to
                            an apparent attitude error. The full maneuver
                            updates prior to the acquisition had defaulted
                            to the roll maneuver updates in initial mode
                            processing.
