                       DAILY REPORT #1848

PERIOD COVERED:  0000Z (UTC) 04/02/97 - 0000Z (UTC) 04/03/97

Daily Status Report as of 093/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

The following scheduled science observations and calibrations could not =
be executed due to the software sun point safing event which occurred at =
090/2314Z:

   1.1 Four Sets of STIS/CCD 7092 (CCD Dark Rate and Read 
       Noise)
   1.2 Completed WF/PC-2 6598 (The Reddest Objects in The 
       Universe)
   1.3 WF/PC-2 6906 (WF/PC-2 Cycle 6 Calibration: Internal 
       Monitor-Visual Flats)
   1.4 WF/PC-2 6703 (Weak Radio Galaxies at Z > 2: Imaging a 
       Unique Sample)
   1.5 WF/PC-2 7019 (WF/PC-2 SMOV Flat Field Check)
   1.6 WF/PC-2 6556 (Rest-Frame Ultraviolet Imaging of Normal 
       Galaxies at High Redshifts)

   1.7 Completed WF/PC-2 6363 (The Environments and Host Galaxies of =
BL-Lac Objects)

       The WF/PC-2 was used to make snapshot survey observations of =
BL-Lac object QSO-0754+1 in order to study its environment and its host =
galaxies.  The goal is to investigate systematic trends in host galaxy =
type, unusual morphological features, nearby companion galaxies, etc.  =
The observations were executed as scheduled, and no anomalies were noted.

   1.8 Completed WF/PC-2 6359 (Core Properties of the Bulges of Spiral =
Galaxies)

       The WF/PC-2 was used to make snapshot survey observations of =
spiral galaxy NGC-1385 in order to study its central bulge.  The aim is =
to investigate the core properties, correlations with global galactic =
properties, and the frequency of occurrence of multiple and/or =
miscentered nuclei.  The observations were completed as scheduled, and no =
anomalies were noted.

   1.9 Completed Two Sets of WF/PC-2 6361 (High Resolution Imaging of =
X-Ray Selected AGNs)

       The WF/PC-2 was used to make high resolution  observations of the =
known, low, red-shifted, x-ray, active galactic nuclei (AGN) MS1108.6+3 =
and MS0754.6+3.  These data will allow a study of the optical properties =
of an unbiased sample of AGN host galaxies.  The observations were =
completed as scheduled, and no problems were reported.

   1.10 Completed WF/PC-2 6346 (Snapshot Survey of the Ultraluminous IRAS =
Galaxy Sample-Part 1 High)

       The WF/PC-2 was used to make snapshot survey observations of the =
ultraluminous IRAS galaxy QDOTULIR09.  These data will be searched for =
multiple cores, which imply a merger has occurred, and for starburst =
regions.  The failed acquisition mentioned in 2.1 occurred just before =
this proposal began, and the take data flag did not come up.  No further =
anomalies were noted.

2.0 FLIGHT OPERATIONS SUMMARY:

2.1 Guide Star Acquisitions: 

                            Scheduled Acquisitions : 7
                                        Successful : 6

       The acquisition at 092/224256Z failed to acquire.  HSTAR 6005 was =
written.

                          Scheduled Reacquisitions : 5
                                        Successful : 5

   2.2 FHST Updates: 

                              Scheduled : 14
                             Successful : 14

   2.3 Operations Notes: 

       NICMOS was transitioned to SAA operations at 092/2332Z.  At =
092/2339Z, NICMOS filter wheel test case 1 was run: at 092/2346Z, NICMOS =
filter wheel test case 2 was run.  NICMOS was commanded to boot mode at =
093/0107Z, and transitioned to boot at 093/0116Z

3.0 SIGNIFICANT FORTHCOMING EVENTS: 

       Continuation of normal science and SMOV operations.
