PERIOD COVERED:  0000Z (UTC) 01/03/96 - 0000Z (UTC) 01/04/96

Daily Status Report as of 004/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed WF/PC-2 6367 (High Resolution Imaging of Nearby Nuclear =
Starbursts)

       The WF/PC-2 was used to make high resolution images of the star =
bursting nuclei in galaxy NGC-2903.  Selected narrow and wide band passes =
were used.  The observations were executed as scheduled, and no anomalies =
were noted.

   1.2 Completed Five Sets of GHRS/1 6171 (CRIMP1: Cycle 5 =
Condensed-Regimen Integrated Monitoring Program)

       The High Resolution Spectrograph (Side One) was used  to obtain =
darks, internal flats (in photoscan mode), wavelength calibrations and =
observations of standard star BD+28D4211.  This includes detector =
calibration, sensitivity monitoring, and wavelength monitoring.  The =
observations were executed as scheduled, and no anomalies were noted. 

   1.3 Completed WF/PC-2 5984 (Absorption - Selected Galaxies)

       The WF/PC-2 was used to study the morphology of galaxy UM18, at =
redshifts from 0.4 to 1.0, that are absorbing light from background =
quasars.  The absorbing galaxies were discovered from ground-based =
surveys.  The observation was completed with no reported anomalies.

   1.4 Completed Two Sets of GHRS/2 6172 (CRIMP2: Cycle 5 =
Condensed-Regimen Integrated Monitoring Program)

       The High Resolution Spectrograph (Side Two) was used  to obtain =
darks, internal flats (in photoscan mode), wavelength calibrations and =
observations of standard star BD+28D4211.  This includes detector =
calibration, sensitivity monitoring, and wavelength monitoring.  The =
observations were executed as scheduled, and no anomalies were noted. 

   1.5 Completed WF/PC-2 5996 (The Morphology of Field Galaxies at High =
Redshifts)

       The WF/PC-2 was used to make observations  of several field =
galaxies (Field-0302) in order to study their morphologies.  The =
observations were completed as planned, and no anomalies were reported.

   1.6 Completed WF/PC-2 6187 (WF/PC-2 Cycle 5 Calibration: Earth Flat)

       The WF/PC-2 was used to make Earth streak flat calibration images.  =
These streak flats will be used to produce flat fields, to map the OTA =
illumination pattern and, in combination with other data, to produce new =
superflats.  The observations were completed as planned, and no problems =
were reported.

   1.7 Completed Two Sets of FOS/RD 5452 (Composition of Dark Material on =
Iapetus: Cycle 4 Medium)

       The Faint Object Spectrograph (Red Side) was used to make
observations of Saturn's moon Iapetus, which has a bright hemisphere and a =
dark hemisphere.  Ultraviolet spectra of both hemispheres were taken.  =
Spectra of Saturn's moon Rhea was also taken for comparison.  The =
observations were completed as scheduled, and no anomalies were noted. 

   1.8 Completed WF/PC-2 6341 (SN1978K: Probing the Shocked Ejecta)

       The WF/PC-2 was used to make observations of the shocked ejecta =
from Super Nova SN1978K which is located in the barred galaxy NGC-1313-03. =
 It is the only example of a very young remnant of known age which is =
x-ray bright.  The observation were completed as planned, and no anomalies =
ere noted.

   1.9 Completed FOS/BL 6244 (HR 4796A: A Possible Protoplanet?)

       The Faint Object Spectrograph (Blue side) was used to make =
observations of object HR-4796A-O which is thought to be a possible =
protoplanet system.  This star is a main sequence A type star with more =
circumstellar dust than is located around Beta Pic.  The observations were =
completed as planned and no anomalies were reported.

   1.10 Completed WF/PC-2 6099 (Black Holes and Cores of Galaxies)

       The WF/PC-2 was used to search for possible black holes in the core =
of nearby early-type galaxy NGC-5845.  The WF/PC-2 will be used to obtain =
high resolution images of its bright core, and to provide sufficiently =
accurate coordinates for the FOS, which will be used to measure the =
velocity dispersion around this galaxy.  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

       One acquisition, at 004/0621Z, failed to fine lock backup, on FGS # =
3 only.  This event is documented in HSTAR 5427.

                          Scheduled Reacquisitions : 9
                                        Successful : 9

   2.2 FHST Updates: 

                              Scheduled : 16
                             Successful : 16

   2.3 Operations Notes: 

       Several temperature monitors exceeded their operational limits =
during this operational day.  Although higher than normal values for many =
temperature parameters can be expected at this time of the year, all limit =
violations were written up in individual HSTARs.

       The ESS, used for data analysis, is scheduled to be down today from =
1:00 p.m. to 5:00 p.m. for maintenance and SM2 preparations.  Should =
priority jobs be required, the system can be made operational within 30 =
minutes.

3.0 SIGNIFICANT FORTHCOMING EVENTS: 

        Nothing at this time.
