PERIOD COVERED:  0000Z (UTC) 04/24/96 - 0000Z (UTC) 04/25/96

Daily Status Report as of 116/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed S/C 5582 (FOC/48 Monthly Activation (Camera Section =
Only): Cycle 4) 

        This proposal was executed as scheduled, and no anomalies were =
noted. 

   1.2 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.

   1.3 Completed WF/PC-2 6360 (A Snapshot Survey of "Radio Load" IRAS =
Galaxies)

       The WF/PC-2 was used to make snapshot survey observations of the =
radio load IRAS galaxy GAL-1011+1.  The WF/PC-2 was used to discern high =
surface brightness structures in its post-starburst active nuclear =
regions.  The observations were completed as scheduled, and no anomalies =
were reported

   1.4 Completed WF/PC-2 6849 (A Photometric Search For Planets of Nearby =
Stars: GTO Prop. Continuation)

       The WF/PC-2 was used to make a photometric search of the nearby =
star L145-141 to look for possible planets.  Images through both the wide =
and narrow-band filters were obtained.  The observations were completed =
as planned, and no anomalies were reported.

   1.5 Completed Five Sets of FOS/BL 6166 (FOS Cycle 5: Location of Spectr=
a and Wavelength Calibration)

       The Faint Object Spectrograph (Blue Side) was used to make =
wavelength calibration images to measure the stability of the FOS Blue =
Side wavelength scale and spectral locations.  A Taled calibration =
observation was also taken.  All observations were completed as planned, =
and no anomalies were reported.

   1.6 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 =
galaxies NGC-4886, IC4001 and NGC4889 which are located in the Coma =
Cluster.  The purpose is to study the luminosity profiles in the central =
nuclear region.  The observations were completed as scheduled, and no =
anomalies were noted.

   1.7 Completed WF/PC-2 6431 (Determination of the Extragalactric =
Distance Scale)

       The WF/PC-2 was used to make observations of the galaxy NGC-4548 =
to be used in measuring the periods of Cepheid variable stars within this =
galaxy.  This will allow for a more accurate estimate of the distances to =
these galaxies through the period-luminosity relation for the Cepheid =
stars.  The observations were executed as scheduled, and no anomalies =
were noted.

   1.8 Completed WF/PC-2 5920 (Extragalactic Globular Cluster System)

       The WF/PC-2 was used to make observations to compile a catalogue =
of the extragalactic globular clusters in galaxy NGC-5846.  A luminosity =
function will be derived which should be complete down to the 27th =
magnitude in V.  The observations was completed as planned, and no =
problems were reported.

   1.9 Completed WF/PC-2 6187 (WF/PC-2 Cycle 5 Calibration: Earth Flat)

       The WF/PC-2 was used to make Earth streak flat calibration images. =
 These streak flats will be used to produce flat fields, to map the OTA =
illumination pattern and, in combination with other data, to produce new =
superflats.  The observations were completed as planned, and no problems =
were reported.

   1.10 Completed WF/PC-2 6761 (The Origin of Shock Emission in =
Proto-Planetary Nebulae)

       The WF/PC-2 was used to make observations of the bi-polar =
proto-planetary nebula M1-92 in order to study the origin of its shock =
emissions.  The objective is to characterize the mass loss during the =
transition to planetary nebula status.  The observations were executed as =
scheduled, and no anomalies were noted.
