PERIOD COVERED:  0000Z (UTC) 06/16/95 - 0000Z (UTC) 06/19/95

Daily Status Report as of 170/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed WF/PC-2 6311 (The Structure of Nova Shells)

       The WF/PC-2 was used to make observations of the shell of recurrent
nova T-Pyxidis. The expansion of the shell, and the size distribution of the
knots in the shell, will be determined. The exposure was shortened when the
guide star acquisition took longer than had been predicted.  HSTAR 5219 was
written to document this event.  Otherwise, the observations were executed as
scheduled, and no other anomalies have been noted.

   1.2 Completed GHRS/1 5719 (Echelle Observations of the Low Red Shift Lyman
Alpha Forest in 3C273)

       The High Resolution spectrograph (Side One) was used to make high
resolution (~4 km/sec) observations of low red shift radio quasar 3C273.0 to
study its Lyman Alpha Forest. The region of interest contains two red shifted
Lyman Alpha lines at 1251.46 and 1255.7 A0. The observations were completed
as planned, and no problems 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 FOS/RD 5695 (Black Holes and Nuclear Dynamics in a Completed
Sample of Virgo Ellipticals)

       The Faint Object Spectrograph (Red Side) was used to make observations
of the nuclear region of elliptical galaxy NGC-4570 which is located in the
Virgo Cluster. The objective is to obtain rotation curves for a region near
the nucleus of this galaxy, and thus obtain the mass of the core. The
observations were completed as planned, and no anomalies were reported.

   1.5 Completed Two Sets of WF/PC-2 6251 (Medium Deep Survey - Crafting
Test)

       The WF/PC-2 was used in this continuation of the medium deep survey. 
The proposal is targeting rare objects (lenses, peculiar galaxies, faint
stars) and sources related to the faint blue galaxy problem.  This
observation was completed with no reported problems.

   1.6 Completed WF/PC-2 5629 (WF/PC-2 Cycle 4 Photometric Calibration
Monitor 1C: 4-Chip STD in F170W)

       The WF/PC-2 was used to make photometric calibration observations of
the ultraviolet standard star GRW+70D582. The observations were executed as
scheduled, and no anomalies were noted. 

   1.7 Completed GHRS/2 5389 (The Nature of Interstellar Cloud Envelopes:
Physical Conditions)

       The High Resolution Spectrograph (Side Two) was used to make
observations of star HD147933 to study the nature of the interstellar cloud
envelopes in the line of sight of the star. The observations were executed as
scheduled and no anomalies were noted.

   1.8 Completed FOC/96 5522 (FOC Post-COSTAR Polarization Calibration)

       The Faint Object Camera (f/96) was used to make polarization
calibration observations using standard object LK-HA-233 as a source to help
find the transmission coefficients. The observations were executed as
scheduled, and no anomalies were noted. 

   1.9 Completed WF/PC-2 6252 (GTO Pure Parallel Program - Cycle 4 Crafting
Test)

       This parallel program uses the WF/PC-2 and target fields at galactic
latitudes above 10 degrees.  Galactic star counts and the structure of the
galactic halo will be studied.  The observation completed as planned, and no
problems were reported.

   1.10 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
GD153. The observations were executed as planned, and no anomalies were
noted.

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

       The WF/PC-2 was used to make snapshot images of radio galaxies 3C458.0
and 3C15.0 as part of a continuum survey and to study the galaxies'
morphology. The observations were executed as scheduled, and no anomalies
were noted.

   1.12 Completed GHRS/1 5542 (GHRS Side One Wavelength (1st Order Gratings):
Cycle 4) 

       The High Resolution Spectrograph (Side One) used the spectral
calibration lamp (Side Two) to calibrate the Side One characteristics. Notice
that the Side Two lamp was used to calibrate Side One. The observations were
executed as scheduled, and no anomalies were noted. 

   1.13 Completed WF/PC-2 5236 (Nuclei of Nearby Normal Galaxies: Cycle 4)

       The WF/PC-2 was used to make observations of nearby galaxy NGC-224-NUC
to obtain luminosity and color gradients, and to search for bright stars,
globular clusters, and interstellar dust. The observations were executed as
scheduled, and no anomalies were noted. 

   1.14 Completed 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.
