PERIOD COVERED:  0000Z (UTC) 12/28/95 - 0000Z (UTC) 01/02/96

Daily Status Report as of 002/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed FOS/RD 6339 (Verification of the UV Spectrum of the HST =
Background Light )

       The Faint Object Spectrograph (Red Side) was used to make =
ultraviolet observations of the HST background light.  These FOS =
observations were taken parallel to Hubble Deep Field (HDF) survey.  Both =
the HDF and these FOS data will be used to test and improve the existing =
engineering model of the HST background light.  The observations were =
completed as planned, and no anomalies were reported.

   1.2 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 =
systems SGP005, SGP001 and SGP008 (all are 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.

   1.3 Completed FGS/WF/PC-2 6062 (HD98800, An Extraordinary Star)

       The WF/PC-2 and the FGSs were used to observe HD98800, a nearby =
multiple star with strong infrared emission.  The infrared emission =
presumably comes from a thick disc around the system.  The proposal will =
measure the strength of the Mg II line at 2800A, and will adress the =
fundamental questions about disk formation, maintenance, and dynamics.  =
The observations were executed as scheduled, and no anomalies were noted.

   1.4 Completed Two Sets of WF/PC-2 5971 (HST Medium Deep Survey)

       The WF/PC-2 was used to make a long exposure medium deep sky survey =
observations at latitudes larger than 10 degrees taken in parallel with =

illumination pattern and, in combination with other data, to produce new =
superflats.  The observations were completed as planned, and no problems =
were reported.

HDF123634, HDF123651, HDF123704, HDF123705, HDF123648 and HDF123718).  The =
observations were executed as scheduled, and no anomalies were noted.

GO/CAL)

       The FGSs were used to make observations of the pre-main sequence =
binary star ZZ-Tau located in the Taurus star forming region.  The FGS =
data will provide the apparent orbits needed to compute the total mass of =
the system.  The observations were executed as scheduled, and no anomalies =
were noted. 

   1.8 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 =

Ultraviolet)

       The WF/PC-2 was used to make ultraviolet observations of object =
GRB79-613 which is thought to be an optical counterpart of a gamma ray =

   1.13 Completed WF/PC-2 6132 (Imaging Young Stellar Objects)

       The Planetary Camera was used to image the environment of  T-Tauri =
star IRAS04303.  Analysis of the images will be used to constrain various =
physical parameters including the initial angular momentum of the =

interaction between highly collimated jets and the protostellar envelopes =
of young stellar objects.  The observation was executed as scheduled, and =
no anomalies were noted.
