PERIOD COVERED:  0000Z (UTC) 04/22/96 - 0000Z (UTC) 04/23/96

Daily Status Report as of 114/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed WF/PC-2 6364 (Snapshot Survey of Proto-Planetary Nebulae =
and AGB Stars)

       The WF/PC-2 was used to make some snapshot survey observations of =
protoplanetary nebular system IRAS04386 to study its circumstellar =
envelope.  The purpose is to discern the evolutionary sequence that =
produces axially-symmetric planetary nebulae.  The observations were =
executed as scheduled, and no anomalies were noted.

   1.2 Completed FOS/BL 6202 (Cycle 5 FOS Spectral Flat field =
Calibration)

       The Faint Object Spectrograph (Blue Side) was used to make =
observations of the white, relatively featureless, white dwarf star =
WD0501+527 in order to make flat field calibration images.  The =
observations were made through the 1.0 aperture, with all usable =
detector/disperser combinations.  The observations were executed as =
schedule, 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 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.

   1.6 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.

   1.7 Completed WF/PC-2 5997 (The Cores of Elliptical Galaxies in the =
Coma Cluster)

       The WF/PC-2 was used to make observations of the large elliptical =
galaxy IC4021 which is located in the Coma Cluster.  The purpose is to =
study the luminosity profiles in the central nuclear region.  As =
documented in HSTAR 5579, the primary guide star acquisition at =
113/133300Z failed.  Two of the observaions for this proposal were =
affected.  The observations were completed as scheduled, and no anomalies =
were noted.

   1.8 Completed FOC/96 6057 (Ultra--High Resolution Studies of AGNs II: =
3C279 Proper Motion)

       The Faint Object Camera (f/96) was used to make ultra-high =
resolution observations of active galactic nuclei in radio galaxy 3C279 =
in order to study the small scale morphology of the AGN.  The data will =
be searched for evidence of superluminal motion, which is known radio =
observations, and for time variable phenomena.  The observations were =
executed as scheduled, and no anomalies were noted.

   1.9 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.

   1.10 Completed WF/PC-2 5910 (The Far-Field Hubble Constant)

       The WF/PC-2 was used to make observations of the Abel galaxy cluste=
r ABELL3742 in order to determine the HST Far-Field Hubble constant.  The =
observations were executed as planned, and no anomalies were reported.
