PERIOD COVERED:  0000Z (UTC) 12/13/95 - 0000Z (UTC) 12/14/95

Daily Status Report as of 348/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed WF/PC-2 5897 (Ages For the Oldest Star Clusters in the =
Large Magellanic Cloud)

       The WF/PC-2 was used to make observations of star cluster NGC-2210 =
which is known to be one of the oldest clusters in the Large Magellanic =
Cloud.  From these data, a color magnitude diagram will be constructed =
that extends below the main sequence turnoff.  The observations were =
completed as planned, and no anomalies were noted.

   1.2 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 =
NGC-3599 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.

   1.3 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.

   1.4 Completed WF/PC-2 5998 (The Evolution of Massive Stars: Closing the =
Loop Observationally)

       The WF/PC-2 was used to  make observations of (OB Class) massive =
star M-31-OB69 (field 6) which is located in the Andromeda galaxy.  The =
goal is to study the evolution of this class of massive stars.  The =
observations were executed as scheduled, and no anomalies were noted.

   1.5 Completed WF/PC-2 5972 (Determination of the Extragalactic Distance =
Scale)

       The WF/PC-2 was used to make observations of the galaxy NGC-3198 =
looking for standard candle Cepheid variable stars.  The purpose of this =
observations is to help estimate the Hubble constant with an accuracy of =
10%.  The observations were executed as scheduled, and no anomalies were =
noted.

   1.6 Completed WF/PC-2 6102 (Chemical Evolution and History of Star =
Formation in the Large Magallanic Cloud)

       The WF/PC-2 was used to make observations of the "Bar" region =
(NGC-2682) in the Large Magellanic cloud to study the chemical evolution =
and the history of star formation in that region.  The goal is to observe =
individual field stars near the main sequence turnoff in order to study =
the large scale process that control star formation and nucleosynthesis in =
galaxies.  The observations were executed as planned, and no anomalies =
were reported.

   1.7 Completed WF/PC-2 5845 (Polarization of Disks around T-Tauri)

       The PC and polarization filter POLQ were used to image the =
nebulosity surrounding the T Tauri star HL-Tau.  These data will test =
various models for scattered light from central sources.  Systematic =
errors will be avoided by using one polarizer and allowing the spacescaft =
roll to provide the rotation by observing the target three times at 120 =
day intervals.  The observations were executed as scheduled, and no =
problems were reported.

   1.8 Completed GHRS/1 5945 (Diffuse Helium Absorption as a Probe of =
Quasar History)

       The High Resolution Spectrograph (Side One) was used to make =
observations of diffuse helium absorption lines in the spectra of quasar =
Q0302-0019 to confirm the detection of intergalactic helium by the FOC.  =
The observations were completed as planned and no anomalies were reported.

2.0 FLIGHT OPERATIONS SUMMARY:

   2.1 Guide Star Acquisitions: 

                            Scheduled Acquisitions : 6
                                        Successful : 6

                          Scheduled Reacquisitions : 9
                                        Successful : 9

   2.2 FHST Updates: 

                              Scheduled : 13
                             Successful : 13

   2.3 Operations Notes: 

       At approximately 347/2010Z, the operations team began to observe =
symptoms of TAC problems.  Eventually, a switch was made from the primary =
rail to the backup rail at 347/2153Z.  As a result, operations was unable =
to utilize a planned Madrid DSN pass.  During this time frame the VDS =
communications system went down for about 30 minutes.

       MOR operations moved to the SAMS backup facility for the scheduled =
weekly checkout.  The DOC was unable to switch over the command lines =
until 348/0005Z due to an unknown problem as the NCC.  Operations moved =
back to the MOR without further incident as 348/0345Z.

       There was no impact to the on-going science programs as a result of =
any of these problems.

3.0 SIGNIFICANT FORTHCOMING EVENTS: 

        Nothing at this time.
