                       DAILY REPORT #1777

PERIOD COVERED:  0000Z (UTC) 12/11/96 - 0000Z (UTC) 12/12/96

Daily Status Report as of 347/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed WF/PC-2 6909 (WF/PC-2 Cycle 6 Calibration: Earth Flats)

      The WF/PC-2 was used to make observations of the bright earth to =
obtain streak flats which are used to construct high quality flat fields =
for the WF/PC-2 filter set.  The observations were executed as scheduled, =
and no anomalies were noted.

   1.2 Completed FOS/RD 6300 (The Nature of the Central UV Source in =
M-31)

       The Faint Object Spectrograph (Red Side) was used to make =
ultraviolet spectrographic observations of the central 0.5 arcsecond regio=
n of galaxy M-31 (aka, NGC-224).  The small aperture will be used to map =
the stellar velocity dispersion and rotation within this grad shaped =
area.  As reported in yesterday's report and in HSTAR 5837, just before =
the beginning of this 15-hour proposal, the primary acquisition and =
immediate re-acquisition obtained fine lock on FGS #2 only.  The =
observations executed as scheduled, and no further anomalous activity was =
noted. 

   1.3 Completed WF/PC-2 6253 (Pure Parallel Archive Program)

       The WF/PC-2 was used to execute a pure parallel program taking =
ultraviolet observations running concurrently with prime science =
observations.  The intent is to search for extra-galactic sources with =
flux excesses at 3000 A0 and galactic sources with excesses at 1600 A0.  =
The observations were completed as planned, and no problems were =
reported.

   1.4 Completed S/C 4974 (DF-224 FS Installation 9.0 and Higher)

       The HST was placed in V3 Sun Point Mode for the loading of Flight =
Software 9.7.2 and 9.7.4.  The operation was completed as scheduled.  No =
significant anomalies were encountered.

   1.5 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 S4-1749+70 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.

   1.6 Completed WF/PC-2 6348 (Blue Continuum Snapshots of 3CR Radio =
Galaxies)

       The WF/PC-2 was used to make some snapshot images of the blue =
continuum in radio galaxy 3C125.0.  Combined with existing data, these =
exposures will provide high spatial resolution information on the color =
distribution within galaxies, redding due to dust, spacial indices of the =
optical synchrotron jets, and colors of the active nuclei and tidal jets. =
 The observations were executed as scheduled, and no anomalies were =
noted.

   1.7 Completed FOC/96 6350 (FOC spectroscopy of BALQSOs)

       The Faint Object Camera (f/96) was used to make ultraviolet =
spectrographic images of BALQSO 0137-0153 which is known to show broad =
emission lines from abundant ions.  This will help us improve our =
knowledge of these BAL class objects.  The observations were executed as =
scheduled, and no anomalies were noted.





2.0 FLIGHT OPERATIONS SUMMARY:

2.1 Guide Star Acquisitions: 

                            Scheduled Acquisitions : 5
                                        Successful : 5

                          Scheduled Reacquisitions : 10
                                        Successful : 10

   2.2 FHST Updates: 

                              Scheduled : 9
                             Successful : 9

   2.3 Operations Notes: 

       The installation and checkout of flight software versions 9.7.2 =
and 9.7.4 was accomplished satisfactorily by 346/2049Z, with only minor =
problems mentioned in HSTAR 5839.  These miscompares and incorrectly set =
safing tests were easily corrected.

       Due to WSGT MA equipment problems, 10 minutes and 59 seconds of =
non-recoverable realtime data was lost, beginning at 347/040001Z.

3.0 SIGNIFICANT FORTHCOMING EVENTS: 

        Nothing at this time.
