PERIOD COVERED:  0000Z (UTC) 05/12/95 - 0000Z (UTC) 05/15/95

Daily Status Report as of 135/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed Three Sets of WF/PC-2 5446 (The Nuclei of Nearby S0 and
Spiral Galaxies: A PC Snapshot Imaging)

       The WF/PC-2 was used to make observations of the core region of galaxy
NGC-4430, UGC-7943, NGC-4330, NGC-4377, IC769, NGC-4339, NGC-4200, NGC-4270,
NGC-4519, NGC-1419 and NGC-4233 to provide statistics on the nuclear cusps,
stellar condensations, and inner stellar disks and dust lanes. The
observations were executed as scheduled, and no anomalies were noted. 

   1.2 Completed WF/PC-2 5574 (WF/PC-2 Cycle 4: Polarization Proposal)

       The WF/PC-2 was used to make observations of NGC-4147 to obtain both
polarized and unpolarized images of the target to calibrate the instrument.
Visual flat observations was also taken. The observations were completed as
planned, and no anomalies were reported.

   1.3 Completed WF/PC-2 5560 (WF/PC-2 Cycle 4 Calibration: Internal Monitor.
1) 

       The WF/PC-2 was used to make several internal bias, K-Spot, and flat
calibration observations to monitor the CCD camera electronics, the optical
alignment, and to check for contamination. The observations were completed as
planned, and no anomalies were noted. 

  1.4 Completed FGS 5686 (Ultra High Resolution Studies of AGNs with the FGS:
Cycle 4 Carryover)

       The FGS#3 was used in the TRANS mode to make astrometric observations
of AGN M-87 which is known to have a milliarcsec structure in their nuclei at
radio wavelengths. If any structure is found, more observations will be made
to look for signs of superluminal motion. The observations were completed as
planned, and no problems were reported.

   1.5 Completed WF/PC-2 5370 (HST Medium-Deep Survey: Cycle 4 Medium, High
Galactic Latitude)

       The WF/PC-2 was used in parallel with the prime science observations
to make high galactic latitude observations as part of a medium-deep sky
survey. The observations were completed as planned, and no problems were
reported. 

   1.6 Completed WF/PC-2 5572 (WF/PC-2 Cycle 4: Photometric Filter
Calibration)

       The WF/PC-2 was used to make images of NGC-5139 to make photometric
calibrations for all of the WF/PC-2 filters. The observations were completed
as planned, and no anomalies were reported. 

   1.7 Completed WF/PC-2  5476 (Continuum Snapshots of 3CR Radio Galaxies) 

       The WF/PC-2 was used to make snapshot images of radio galaxies 3C187.0
and 3C268.2 as part of a continuum survey and to study these galaxies'
morphology. The observations were executed as scheduled, and no anomalies
were noted.

   1.8 Completed Two Sets of FOS/BL 6146 (FOS Location of Spectra and
Aperture - Part 2)

     The Faint Object Spectrograph (Blue Side) was used to conduct a test to
determine the repeatability of positioning the filter-grating wheel. All
observations were internal. A wave length calibration image was also taken.
All observations were executed as scheduled, and no anomalies were noted.

   1.9 Completed WF/PC-2 5479 (Subarcsecond Structure in Nearby AGNs)

       The WF/PC-2 was used to make snapshot observations of the nearby
active galactic nuclei of MARK938 and TOL2327-02 to study the interactions
between the central  engine, the stars, and the interstellar matter in these
AGNs. The observations were executed as scheduled, and no anomalies were
noted. 

   1.10 Completed Two Sets of GHRS/2 5382 (Boron as a Probe of the formation
of the Galactic Halo)

       The High Resolution Spectrograph (Side Two) was used to make
observations of the low-metallicity halo star BD-13D3442 to help learn more
about the chemical and dynamical evolution of the galaxy. The observations
were executed as scheduled, and no anomalies were noted.

   1.11 Completed FOS/BL 5658 (White Dwarf Calibration)

       The Faint Object Spectrograph (Blue Side) was used to make absolute
sensitivity calibrations of the detectors using standard white dwarf star
HZ43. The observations were executed as planned, and no anomalies were noted.
