Daily Status Report as of 089/1200Z.

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed WF/PC-2 5565 (WF/PC-2 Cycle 4: Photometric Calibration
       Monitor: Fields)

       The WF/PC-2 was used to make photometric calibration observations by
       taking images of the large globular cluster Omega Centauri (aka,
       NGC-5139) to help determine astrometric and optical stability of the
       WF/PC-2. The OSS monitored a total of ten observations, and assessed
       the data quality. No anomalies were noted, except for recenterings.

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

       The WF/PC-2 was used to make snapshot images of radio galaxies
       3C303.1 and 3C14.1 as part of a continuum survey and to study the
       galaxies' morphology. Two images were received and displayed. One
       was okay but encountered some recentering, and the other was
       executed in fine lock with no apparent problems.

   1.3 Completed Two Sets of WF/PC-2 4709 (WF/PC-2 Internal Monitor)

       The WF/PC-2 camera was used to make a series of routine ultraviolet
       flat calibration images to monitor the instrument's performance. The
       observations were monitored in the OSS, and the data quality was
       assessed. All three observations were reported to be underexposed.

   1.4 Completed WF/PC-2 5415 (The Distance to M-96 Galaxy Group: Cycle 4
       Medium)

       The WF/PC-2 was used to make observations of Cepheid variable stars
       within the galaxy UGC-5889 which itself is located in the M-96
       galaxy cluster. This is to help determine the distance to this
       galactic group, and to improve the determination of the Hubble
       constant. Four observations were received and displayed. There were
       FGS recentering during each exposure. In addition the guide star
       re-acquisition for the last observations was completed late, so the
       Take Data Flag (TDF) didn't come up until nine seconds into the
       exposure. The shutter didn't open until the TDF was up, so the
       exposure was nine seconds short.

   1.5 Completed WF/PC-2 5570 (WF/PC-2 Cycle 4 Calibration: Earth Flats,
       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 15 images were
       received and displayed. One was saturated, five were underexposed,
       and rest were okay. One observation still remains on the science
       tape recorder, and will be analyzed later.

   1.6 Completed FOC/BL/RD 5626 (SMOV FOS Plate Scale (Revisited - Replaces
       5617))

       The Faint Object Camera (Both Red and Blue Sides) was used to make
       plate scale calibration observation of cluster NGC-188-255. The
       onboard target acquisition was received in real time and left the
       target well centered. The IMAGE-mode observations were executed with
       no apparent problems. Complete analysis is pending the science tape
       recorder dump. No anomalies were noted.

   1.7 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. Several different filters were
       used. The observations were taken in parallel with other prime
       science observations. The observations were executed as scheduled,
       and no anomalies were noted.

2.0 FLIGHT OPERATIONS SUMMARY:

    2.1 Guide Star Acquisitions:

                            Scheduled Acquisitions : 6
                                        Successful : 6
                          Scheduled Reacquisitions : 10

   2.2 FHST Updates:

                              Scheduled :7
                             Successful :7

   2.4 Operations Notes:

       The FOS/FGS fine alignment (blue) of small apertures was the only
       SMOV activity accomplished during week #15.  SMOV functions still to
       be accomplished are: FOS/FGS fine alignment (red) of small
       apertures, FOS plate scale, the GHRS ERO with a supporting WF/PC-2
       observation, and a repeat of the FOS ERO to correct a target
       acquisition/pointing problem. With the exception of the last item
       which will be scheduled as soon as possible within STScI scheduling
       guidelines, all SMOV activities are scheduled to be completed by
       April 3, 1994.

       For this 24-hour period, each HST subsystem reported trouble-free
       operations.
