PERIOD COVERED:  0000Z (UTC) 02/12/96 - 0000Z (UTC) 02/13/96

Daily Status Report as of 044/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 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 NGP007 (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.

   1.2 Completed FGS 6270 (The Parallax of RW Tri)

       The FGS were used in the POS mode to make astrometric observations =
of old nova RW Tri and several other reference stars to measure its =
parallax.  The observations were completed as planned, and no anomalies =
were noted.

   1.3 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.

   1.4 Completed Four Sets of WF/PC-2 6188 (WF/PC-2 Cycle 5 Calibration: =
Dark)

       The WF/PC-2 was used to make internal dark calibration images.  The =
observations were completed as scheduled, and no problems were reported.

   1.5 Completed GHRS/1 5896 (Detailed Studies of High Velocity Ionized =
Gas in Galactic Disks)

       The High Resolution Spectrograph (Side One) was used to make =
observations of star HD37742 in order to study high velocity ionized gas =
in its line of sight to help study the gas in our galactic disk.  The =
observations were completed as planned, and no anomalies were reported.

   1.6 Completed WF/PC-2 6345 (Determining the Binary Frequency for =
Ultra-Cool, Nearby M Dwarf Stars)

       The WF/PC-2 was used to make observations of ultra-cool, nearby, M =
class dwarf star LP412-31 to determine the frequency for it being a binary =
system and try to detect stellar and sub-stellar companions.  The =
observations were executed as scheduled, and no anomalies were noted.

   1.7 Completed FOS/BL 6103 (Ne VIII 774 Emission From QSOs)

       The Faint Object Spectrograph (Blue Side) was used to make =
observations of QSO PKS0355-48 in order to study its Ne VIII 774 =
emissions.  Confirmation of this very high ionization line would tell much =
about the physical conditions within the QSO.  A wavelength calibration =
image was also taken.  The observations were completed as scheduled, and =
no anomalies were reported.

   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 =
flux excesses at 3000 A0 and galactic sources with excesses at 1600 A0.  =
The observations were completed as planned, and no problems were reported.

   1.9 Completed WF/PC-2 6344 (Low - Mass Binaries in the Hyades - =
Completing the Survey)

       The WF/PC-2 was used to make observations of the low mass binary =
star RHY143 (M-Class dwarf stars) which is located in the Hyades Cluster.  =
The observations were executed as scheduled, and no anomalies were noted.

   1.10 Completed WF/PC-2 5989 (Imaging of CL1358+62 and Its Environs: the =
Morphology-Density Relation))

       The WF/PC-2 was used to make imaging observations of galactic =
cluster CL1358+62 (aka, Gal-Clus-1) in order to study the morphology of =
the galaxy as a function of its position in the cluster.  The observations =
were executed as scheduled, and no anomalies were noted.

   1.11 Completed FOS/BL 6109 (Spectropolarimetry of Low Redshift Quasars)

       The Faint Object Spectrograph (Blue Side) was used to make =
spectropolargraphic observations of the low redshifted quasar 0117+213.  =
The wavelength range of interest is from 200 Angstroms below the Lyman =
limit to just above Lyman-Alpha.  The observations were completed as =
planned, and no problems were reported.

   1.12 Completed WF/PC-2 5971 (HST Medium Deep Survey)

       The WF/PC-2 was used to make a long exposure medium deep sky survey =
observation at latitudes larger than 10 degrees taken in parallel with the =
prime science observations.  The observations were executed as scheduled, =
and no anomalies were noted.
