Daily Status Report as of 053/1200Z.

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed Two Sets of WF/PC-2 5240 (SMOV-WF/PC-2 Flat Fields
       Calibration)

       The WF/PC-2 was used to make a set of visual internal flat images.
       Six images were received and displayed. One image was reported to be
       underexposed, and the others were okay.

   1.2 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. Five images
       were received and displayed in the OSS. All five images were
       reported to look okay.

   1.3 Completed FOC/96 5150 (Pluto and Charon)

       The Faint Object Camera (f/96) was used to make observations of the
       planet Pluto and its moon Charon. Pluto was reported to subtend 10
       pixels, and Charon about 5. The two bodies were separated by about
       30 pixels. Four images were received and displayed. The images were
       reported to be excellent!

   1.4 Completed FOC/96/WF/PC-2 5435 (The Hot Stellar Component in the
       Centers of M-31 and M-32: Cycle 4 Medium)

       The Faint Object Camera was used to make images of hot stellar stars
       in the central region galaxy M-32 (NGC-221, aka, the Andromeda
       Galaxy) to measure the far ultraviolet flux from the old metal rich
       stellar populations. The observations were completed under fine
       lock. Several images were reported to be saturated, and several
       images showed no sign of the target.

   1.5 Completed WF/PC-2 5104 (Peculiar and Interacting Galaxies (WC01):
       Cycle 4)

       The WF/PC-2 was used to make images of galaxy IC391. The OSS
       monitored the observations, assessed the data quality. Two images
       were received and displayed in the OSS. They both were reported to
       look very good!

   1.6 Completed FGS 5336 (Linking the HIPPARCOS to the Extragalactic
       Reference Frame: NEWHIP-B)

       The Fine Guidance Sensor #3 was  used to make two sets of
       astrometric observations of object NEWEGOB-34. This object lies near
       the apparent position of extragalactic objects. This object will
       also be observed with the HIPPARCOS satellite. This data will be
       used to determine the systematic rotational offset of the reference
       frame of the HIPPARCOS astrometric satellite. The observations were
       executed as scheduled. No anomalies were reported.

   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. One observations was received and displayed.
       The pointing control was almost continuously recentering during this
       observation. Also, the cosmic ray density was reported to be high.

   1.8 Completed Two Sets of WF/PC-2 5612 (SMOV WF/PC-2 Decontamination)

       The WF/PC-2 Was used to do decontamination operations. Observations
       of standard  A+81D266, and K- Spot observations were also taken. A
       total of nine observations were monitored and displayed. Except for
       one short period of recentering, all of the observations were
       reported to be nominal.

   1.9 Completed GHRS/1 5274 (GHRS Side One Pulse Height Analysis/Ion Test:
       Cycle 4)

       The High Resolution Spectrograph (Side One) was used to make a
       standard pulse height analysis (PHA) test on the detector. These
       were internal observations, which will be used to measure the diode
       response as a function of the threshold settings. In addition, an
       ion test was also conducted. The OSS monitored the observations, and
       no problems were reported.

   1.10 Completed GHRS/1 5275 (GHRS Side One Threshold Adjustment Test:
       Cycle 4)

       The High Resolution spectrograph was used conduct an engineering
       test to measure the threshold levels for the noisy channels.
       Internal flats and darks were both taken. The OSS monitored the
       observations, and no anomalies were noted.

   1.11 Completed FOS/RD/COSTAR 5604 (COSTAR/FOS Fine Alignment - Focus
        Repeat of 4745 With New Target)

       The scheduled Y-Tilt and X-Tilt adjustment for the COSTAR FOS mirror
       was completed as scheduled with no problems. Observations were made
       using standard star WD501+527. The observations were received and
       displayed in real time. No anomalies were noted.

                                        Successful : 3


       One reacquisition may have terminated early due to a SBREL failure.

   2.3 Significant HSTARs: None

   2.4 Operations Notes:

       SMOV activities continue uneventfully, and on schedule.

       At 0212Z this morning, approximately five minutes after a day/night
       transition, the low body error rate test failed and all gyros went
       to high mode.  The gyros were recovered to the low mode at 0527Z
       using an established contingency operations procedure.  There were
       no other reported problems in any HST susbystem.
