PERIOD COVERED:  0000Z
Daily Status Report as of 217/1200Z.

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed Two Sets of WF/PC-2 5655 (WF/PC-2 Cycle 4 Calibration:
         Internal Monitor. 2: Flats Part 2)
The WF/PC-2 was used to make both dark and visual flats. The
observations were completed as planned, and no problems were reported.

   1.2 Completed Three Sets of 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 completed as planned, and no problems were reported.

   1.3 Completed WF/PC-2 5370 (HST Medium-Deep Survey: Cycle 4 High, High
         Galactic Latitude)

The WF/PC-2 was used in parallel with the prime science observations
to make high galactic latitude observations as part of a medium-deep sky
survey. The observations were completed as planned, and no problems were
eported.

   1.4 Completed FOS/RD 5529 (Cycle 4 FOS Discriminator Test)

The Faint Object Spectrograph (Red Side) was used to run
discriminator tests to determine if the discriminator settings need
adjustment from the Cycle 3 Values. Dark, Internal Flat, and Wave
calibrations observations were taken. The Observations were executed as
scheduled, and no anomalies were noted.

   1.5 Completed FOC/96 5522 (FOC Post-COSTAR Polarization Calibration)

The Faint Object Camera (f/96) was used to make polarization
calibration observations using standard object NGC-5272 as a source to help
fine the transmission coefficients. The observations were executed as
scheduled, and no anomalies were noted.

   1.6 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, but a small segment was lost due to a taperecorder track change.

   1.7 Completed FOC/96 5526 (FOC UV Throughput Monitoring: Cycle 4)

The Faint Object Camera (f/96) was used to make calibration observations
using  BPM16274. HST underwent 1 guide star recentering(s) for a total of 5
seconds.  During the recentering the interval HST's pointing was controlled
by gyros, which allow a small amount of drift during the interval.

   1.8 Completed Two Sets of GHRS/1 5595 (GHRS ECH-A Wavelength Monitor:
       Cycle 4)

The High Resolution Spectrograph was used to make wavelength spectral
lamp calibration observations to measure the instrumental characteristics 
of
the Echelle-A spectrograph. The observations were executed as scheduled,
and no anomalies were noted.

   1.9 Completed Two Sets of 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 NGC-2985 to study the interactions between the central
engine, the stars, and the interstellar matter in the AGN. The observations
were executed as scheduled, and no anomalies were noted.

   1.10 Completed WF/PC-2 5563 (WF/PC-2 Cycle 4 Photometric Calibration
       Monitor 1: UV /OPT STD.)

The WF/PC-2 was used to make photometric calibration images of
ultraviolet standard star GRW+70D582 and monitor the photometric stability
and quantum efficiency of the WF/PC-2. The observations were completed as
planned, and no problems were reported.

2.0 FLIGHT OPERATIONS SUMMARY:

                            Scheduled Acquisitions : 7

                                                Successful : 9

   2.2 FHST Updates:

                              Scheduled :13
                             Successful :13



   2.3 Significant HSTARs:

HSTAR 4863: documents a suspected problem with some element of the ground
software.  The events printout shows a termination of the telemetry link to
the ESS at the same time data was acquired after a switch to 32k telemetry.


   2.4 Operations Notes:

A small adjustment in the COSTAR's FOC M1 mirror in X tilt was
made on 215/1400z to remove residual coma in the FOC PSF.
The result will be more symmetrical PSF, especially in the UV.
The move was a single motor step in the negative direction
(1 motor step = 7.2 a-s in tilt).  Due to hysteresis within the
mechanism the commanding required to achieve a single negative
motor step was -46 steps, +45 steps.

On day 215 at approx. 04:28 the WFPC-2 science data interface hung due to
a PMDB editting error which caused infrequently used WFPC shutter
commands to overlap into a WFPC science data read-out.  These
infrequently used commands slowed the read-out of the WFPC CCDs.
Since WFPC command execution is synched with the major frame a
commanding an entire minute.  The delay in the following read-out,
causing the WFPC interface to hang.  This ultimately caused a SDF
lockout.  The SDF and WFPC science data interface were recovered
via r/t commanding on 215/1800z.
