PERIOD COVERED:  0000Z (UTC) 01/22/96 - 0000Z (UTC) 01/23/96

Daily Status Report as of 023/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 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.

   1.2 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 =
system NGP012 (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 6263 (Parallax of Delta Cephei)

       The FGSs were used to make astrometric observations of the variable =
star Delta Cephei to measure its parallax distance.  Delta Cepheid is a =
prototypical Cepheid variable star.  HST observations could reduce the =
uncertainty of its distance to 15%.  The observations were completed as =
planned, and no problems were reported.

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

       The WF/PC-2 was used 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.

   1.5 Completed Two Sets of 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 =
stars RHY064 and RHY402 (M-class dwarf stars) which are located in the =
Hyades Cluster.  The observations were executed as scheduled, and no =
anomalies were noted.

   1.6 Completed FOS/BL 6038 (Winds of Massive Stars in Nearby Galaxies, =
the WR Stars)

       The Faint Object Spectrograph (Blue Side) was used to make =
spectrographic observations of the massive Wolf-Rayette star M-33-FUV444 =
which is located in the M-33 Galaxy in order to study its stellar winds.  =
The observations were completed as planned, and no problems were reported.

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

       The Planetary Camera was used to image the environments of T-Tauri =
class star IRAS04248.  Analysis of the images will be used to constrain =
various physical parameters including the initial angular momentum of the =
protostellar cloud cores, the radii of circumstellar disks and 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.

   1.8 Completed FOS/BL 6206 (FOS Polarimetry Calibration)

       The Faint Object Spectrograph (Blue Side) was used to determine the =
most useful spectropolarimetric modes.  The investigators will determine =
the locations of the polarization spectra, the transmission of the =
polarizer, the angles of the Wollaston prisms and waveplates in celestial =
coordinates, and the instrumental polarization.  The observations were =
completed as planned,  and no anomalies were reported.

   1.9 Completed Two Sets of Sets of WF/PC-2 5760 (The Search for Super =
Planets Around Weak T-Tauri Stars)

       The WF/PC-2 was used to make I-Band observations of T-Tauri Class =
star HBC405 in order to search for possible super planets by looking for =
thermal radiation from the planets in orbit around these stars.  The =
observations were completed as scheduled, and no problems were reported. 

   1.10 Completed Two Sets of WF/PC-2 6119 (Snapshot Survey for Companions =
of Planetary Nebula Nuclei)

       The WF/PC-2 was used to make snapshot survey observations of =
planetary nebula K1-14 to study its nuclei and to look for possible =
companions.  The observations were executed as scheduled, and no anomalies =
were noted.

   1.11 Completed FOS/RD 5639 (HST Spectrograph of Cygnus A-II)

       The Faint Object Spectroscope (Red Side) was used to make =
spectrographic observations of nucleus of 3C405 (aka, Cygnus A-11) and =
several offsets.  One offset spectrographic observation was a plasma knot =
to the northwest of the nucleus.  The observations were executed as =
scheduled, and no anomalies were noted.

   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 =
observations 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.
