PERIOD COVERED:  0000Z (UTC) 12/12/95 - 0000Z (UTC) 12/13/95

Daily Status Report as of 347/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed WF/PC-2 6184 (WF/PC-2 Cycle 5 Photometric Calibration =
Monitor UV/OPT STD)

       The WF/PC-2 was used to make ultraviolet and optical observations =
of standard star GRW+70D582 in order to monitor the photometric =
calibrations of the camera and to check for decontamination.  The =
observations were executed as scheduled, and no anomalies were noted.

   1.2 Completed Two Sets of WF/PC-2 6058 (Direct Imaging of a =
Circumstellar Disk: Beta Pictoris)

       The WF/PC-2 was used to make observations of the circumstellar disk =
on the star Beta Pictoris (aka, HD39060) in order to study the brightness =
profile of the disk.  During the first iteration of this proposal, there =
was a three minute, 29 second loss of lock starting at 346/042924Z.  The =
take data flag went down as a SIP was being commanded.  HSTAR 5401 was =
written.  Otherwise, the observations were completed as scheduled, and no =
anomalies were noted.
 
   1.3 Completed FOS/BL 5851 (Post Asymptotic Giant Branch Evolution in =
the Magellanic Clouds)

       The Faint Object Spectrograph (Blue Side) was used to make =
ultraviolet observations of the planetary nebula LMC-SMP62 which is =
located in the Large Magellanic Cloud.  Extensive ground-based and HST =
observations and imaging work has already been done on this object.  The =
observations were completed as planned, and no problems were reported.

   1.4 Completed WF/PC-2 5999 (The Nuclear Structure of S0 Galaxies: A PC =
Imaging Survey)

       The WF/PC-2 was used to make observations of S0 class galaxy IC3131 =
in order to study its nuclear structure.  This is a part of a large survey =
of S0, E/S0, and S0/a class galaxies.  The targets will cover a wide range =
in luminosity and environment.  The observations were completed as =
planned, and no anomalies were noted.

   1.5 Completed Two Sets of FGS 6239 (Duplicity Among Hyades Stars Cycle =
5, High)

       The FGSs were used in the TRANS Mode to make astrometric =
observations of stars VA43 and VA68 which are located in the Hyades Star =
Cluster to see if these stars are possible doubles.  Each of these stars =
may have a very low mass main sequence companion or a degenerate =
component.  The observations were executed as scheduled, and no anomalies =
were noted.

   1.6 Completed WF/P-2 6254 (GTO Pure Parallel Program - Cycle 5)

       The WF/PC-2 was use to make random long exposures of high galactic =
fields taken in parallel with the prime science observations to obtain a =
random sample of galaxies.  The observations were executed as scheduled, =
and no anomalies were noted.

   1.7 Completed WF/PC-2 5913 (Low-Mass Binaries and Luminosity Fuction)

       The WF/PC-2 was used to make observations of the low-mass binary =
system SGP012 (late type class M dwarf stars).  The intent is to determine =
why the local stellar luminosity function is flat below Mv=3D12, while =
that found from more distant stars falls by an order of magnitude by =
Mv=3D14.  The observations were executed as scheduled, and no anomalies =
were noted.

   1.8 Completed FOS/BL 5581 (Pulsating White Dwarf DN Draconis)

      The Faint Object Spectrograph (Blue Side) was used in the rapid mode =
to cover the 17.1 hour beat period of the pulsating DA white dwarf DN =
Draconis (aka G226-29) to determine the index of the pulsational mode =
which will allow for the outer hydrogen layer to be determined.  The =
observations completed nominally with no reported problems.

   1.9 Completed Three Sets of WF/PC-2 6183 (WF/PC-2 Cycle 5 Calibration: =
Decon)

       The WF/PC-2 was used to make some internal flat, K-Spot, and dark =
calibration images.  The purpose is to define decontamination procedures =
to be run during Cycle 5.  The calibration observations were completed as =
scheduled, and no anomalies were reported.

2.0 FLIGHT OPERATIONS SUMMARY:

   2.1 Guide Star Acquisitions: 

                            Scheduled Acquisitions : 8
                                        Successful : 8

                          Scheduled Reacquisitions : 5
                                        Successful : 5

   2.2 FHST Updates: 

                              Scheduled : 15
                             Successful : 15

   2.3 Operations Notes: 

       There was a two minute, 22 second data dropout during STGT =
operations for unknown reasons.  The data is recoverable.  A TTR was =
written.

       Operations personnel are monitoring HST telemetry on a parallel =
backup string which is using the new PRS TTAC software.  Other than some =
minor set-up problems, all subsystem operations appear to be nominally =
supported with the new system.

3.0 SIGNIFICANT FORTHCOMING EVENTS: 

        Nothing at this time.
