PERIOD COVERED:  0000Z (UTC) 06/11/97 - 0000Z (UTC) 06/12/97

Daily Status Report as of 163/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed Two Sets of WF/PC-2 6909 (WF/PC-2 Cycle 6 Calibration:
Earth Flats

       The WF/PC-2 was used to make observations of the bright Earth to
obtain streak flats which are used to construct high quality flat fields
for the WF/PC-2 filter set. The observations were executed as scheduled,
and no anomalies were noted.

   1.2 Completed Two Sets of NIC/1/2/3 7701 (NICMOS Short One Orbit Parallel)

       The Near Infrared Camera (Cameras One, Two and Three) was used as
part of a short NICMOS one orbit parallel program, to obtain "JHK" imaging
of sky regions when another instruments prime.  The observations were
completed as scheduled, and no anomalies were reported.

   1.3 Completed WF/PC-2 6802 (Cosmology With the Medium Deep Survey)

       The WF/PC-2 was used to make observations taken in parallel with the
prime science observations as part of the Medium Deep Sky Survey.  The
observations were executed as scheduled, and no problems were reported.

   1.4 Completed Two Sets of STIS/CCD 7700 (STIS Non-Scripted Parallel
Archive Proposal)

       The Space Telescope Imaging Telescope (CCD) was used to obtain
slitless spectroscopy with the G750L grism to search for emission line
galaxies at intermediate to high redshift.  Field galaxy surveys have shown
that at high redshift most galaxies have strong emission lines, and are
compact and blue.  This suggests that star formation rates were higher than
at present,and that AGN may have been more frequent.  The low background
and high resolution of HST separates these objects from the background.
The proposal completed as planned, and no problems were reported.

   1.5 Completed STIS/CCD 7036 (NICMOS SAA Contour Test)

       The Space Telescope Imaging Spectrograph (CCD) was used to make
observations of an object as the spacecraft passed through the South
Atlantic Anomaly in order to obtain data to plot the contour plot of the
radiation effects.  This test is to determine optimal South Atlantic
Anomaly (SAA) limits for detector operations, and determine orbital
radiation effects on the NICMOS dark current when coming out of the SAA.  A
waveline calibration image was also taken.  The observations were completed
as scheduled, and no anomalies were reported.

   1.6 Completed WF/PC-2 6598 (The Reddest Objects in The Universe)

       The WF/PC-02 was used to make observations of the object ERO0905+34
which is known to be one of the reddest objects in the universe.  This is
one of the members of a recent deep K-Band imaging surveys which discovered
a new population of infrared bright, extremely red (R-K~gt 6 class),
objects (EROS).  The observations were completed as scheduled, and no
anomalies were reported.

   1.7 Completed Eight Sets of STIS/CCD 7675 (STIS Non-Scripted Parallel
Archive Proposal)

       The Space Telescope Imaging Spectrograph (CCD) was used in the
parallel mode to obtain slitless spectroscopy with the G750L grism to
search for emission line galaxies at intermediate to high redshift.  The
observations were completed as planned, and no anomalies were reported.

   1.8 Completed WF/PC-2 6776 (A Comparative HST Imaging Study of Radio
Galaxies and Hosts)

       A clear understanding of the nature of the host galaxies of
radio-quiet quasars, radio-loud quasars and radio galaxies is of central
importance in any attempt to unify and relate the three main classes of
powerful active galaxies.  Existing HST studies of quasar hosts, while
producing many interesting new results, have yielded surprisingly little
hard information on the properties of the hosts themselves.  This imaging
study using the WF/PC-2 will remedy this situation by undertaking redder,
line-free observations of our three matched AGN samples.  The proposal
completed with no reported problems.

   1.9 Completed WF/PC-2 5984 (Absorption - Selected Galaxies)

       The WF/PC-2 was used to study the morphology of galaxy PG1222-228,
at redshifts from 0.4 to 1.0, that is absorbing light from background
quasars.  The absorbing galaxies were discovered from ground-based surveys.
The observation was completed with no reported anomalies.

   1.10 Completed Six Sets of NIC/1/2/3 7676 (NICMOS-One Orbit Parallel)

       The Near Infrared Camera (Cameras One, Two and Three) was used to
conduct an on-orbit calibration procedure.  This was done in parallel with
the prime science observations.  The procedure was completed as scheduled,
and no anomalies were noted.

   1.11 Completed WF/PC-2 6821 (Optical Counterparts for Low-Luminosity
X-Ray Sources)

       This proposal uses narrow band H-alpha imaging with the WF/PC-2 to
search for optical counterparts for low-luminosity x-ray sources in the
globular cluster Omega Cen.  Remarkably little is known about this class of
cluster x-ray sources, yet it apparently constitutes the largest known
population of compact binary stars in globulars.  The observations
completed, and no anomalies were reported.

   1.12 Completed STIS/MA1 7086 (STIS22MB STIS Slit to Detector Internal
Stability - MAMA - Part 2)

       The Space Telescope Imaging Spectrograph (MA1) was used to make
slit-to-detector internal stability calibration observations.  This was to
determine the stability of the spectrograph-to-thermal variations in the
MAMA modes.  A dark calibration image was also taken.  The observations
were executed as scheduled, and no anomalies were noted.

   1.13 Completed WF/PC-2 6740 (Hyper-Luminous IRAS Galaxies: Star
Formation, AGN or LENSES?)

       The WF/PC-2 was used to make observations of the hyper-luminous IRAS
galaxy FSC15307+3 in order determine if its luminous state is a result to
its being a gravitational lens system or an active galactic nuclei (AGN)
system.  This IRAS galaxy is known to emit an enormous amount of power
(>10^13 LSUN) in the far infrared.  The observations were completed as
planned, and no anomalies were reported.

   1.14 Completed NIC/1/2/3 7708 (NICMOS MULTIACCUM Dark Characterization 6/8)

       The purpose of this proposal is to obtain group 6 of the on-orbit
darks for the MULTIACCUM predefined sequences requested by GOs, before the
start of Cycle 7.  The observations completed with no reported problems.

   1.15 Completed STIS/MA2 7138 (Imaging and Spectroscopy of the Bright
Arcs Around the Most Luminous X-Ray Cluster RXJ 1347.5-1145)

       The Space Telescope Imaging Spectrograph (MA2) was used to make
observations of the arcs surrounding the cluster RXJ 1347.5-1145 which is
the brightest known X-ray cluster.  The observations taken from 162/20:33Z
through 162/23:03 were part of the early release program. The cluster
itself is at a redshift of 0.451 and there are two bright arcs
symmetrically situated at about 35 arcseconds from the brightest cluster
member.  The observations were completed as planned and no problems were
reported.
