PERIOD COVERED:  0000Z (UTC) 06/25/97 - 0000Z (UTC) 06/26/97

Daily Status Report as of 177/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed STIS/CCD 7659 (Daily Darks to Update Acquisition Bad Pixel
Table)

       The Space Telescope Imaging Spectrograph (CCD) was used to make dark
calibration images in order to update the acquisition bad pixel table.
Daily hot pixel lists can also be used for science data analysis.  The
observations were executed as scheduled, and no anomalies were noted.

   1.2 Completed WF/PC-2 7450 (The Formation of Bulges of Spiral Galaxies:
Central Visual-Infrared Color Gradients)

       The WF/PC-2 was used to make observations of the bulge in spiral
galaxy NGC-5475 in order to obtain high-resolution optical and near
infrared images for a complete survey sample of bulges of spiral galaxies.
The observations were completed as scheduled, and no anomalies were
reported.

   1.3 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.

   1.4 Completed NIC/2 7330 (The Fueling of Active Nucleii: A NICMOS
Snapshot Survey)

       The Near Infrared Camera (Camera Two) was used to probe the dark
matter distribution of NGC-5614, far from the center, by observing
intervening absorption from the MgII doublet (lambda 2800) in the spectrum
of one background QSO located in a geometrically optimal position.  HST
observations are required because this feature is in a wavelength range not
accessible from the ground, and the QSO magnitudes and expected strength of
absorption make IUE observations unfeasible.  The proposal completed as
expected with no anomalies.

   1.5 Completed WF/PC-2 6194 (WF/PC-2 Cycle 5: Polarization Proposal)

       The WF/PC-2 was used to make polarization observations of star
BD+64D106 at four different spacecraft roll angles.  This should permit a
detailed and independent calibration of each polarizer quad.  A visual flat
calibration image was also taken.  The observations were executed as
scheduled, and no anomalies were noted.

   1.6 Completed STIS/CCD 7063 (STIS SMOV CCD Contamination Monitor)

       The Space Telescope Imaging Spectrograph (CCD) was used to make
observations of standard star GD153 in order to  measure flux and look for
any gross changes over time that might indicate contamination.  The
observations were completed as scheduled, and no anomalies were reported.

   1.7 Completed STIS/CCD 7068 (STIS CCD Diffuse Source Acquisition (STIS 11))

       The Space Telescope Imaging Spectrograph (CCD) was used to make
images of the defuse object NGC-1399.  This is to demonstrate the ability
of the STIS flight software to locate the brightest region in a diffuse or
extended source within an acquisition aperture, determine the position of a
spectroscopic slit, and position the target within the slit.  The
observations were executed as scheduled, and no anomalies were noted.

   1.8 Completed Three Sets STIS/MA2 7604 (Cycle 7 MAMA Dark Measurements)

       The Space Telescope Imaging Spectrograph (MA2) was used to make MAMA
dark measurements.  These darks will be used in later image reductions and
also trended over the instrument's life time as an indicator of the
detector's degradation or damage.  The observations were completed as
scheduled, and no problems were reported.

   1.9 Completed Two Sets of WF/PC-2 6452 (Global and Temporal Coverage of
a Atmospheric Regions of the Planet Jupiter)

       The WF/PC-2 was used to make observations of selected regions of the
planet Jupiter in order to investigate its atmospheric dynamics.  These
data will be used in the interpretations of the observations made from the
Galileo Mission.  The observations were executed as scheduled, and no
anomalies were noted.

   1.10 Completed WF/PC-2 6509 (Jovian Global Photometry during the Galileo
Epoch)

       The WF/PC-2 was used to make observations of the planet Jupiter to
coincide which observations taken with the Galileo spacecraft.  These data
will be used to study the vertical aerosol structure of the Jovian
atmosphere as well as its spatial and temporal variability.  The
observations were completed as planned, and no anomalies were reported.

   1.11 Completed Two Sets of STIS/MA2 7098 (Band I and Band II Flat Field
Uniformity)

       The Space Telescope Imaging Spectrograph (MA2) was used to make Band
1 and Band 2 flat field uniformity calibration observations, and to measure
high S/N DFLAT to assess flat field uniformity, and to compare to lab
calibrations.  The observations were completed as planned, and no anomalies
were reported.

   1.12 Completed WF/PC-2 6836 (Light Curve of an Eclipsing Millisecond Pulsar)

       The WF/PC-2 was used to make observations of the eclipsing
millisecond pulsar PSRJ2051-0 in order to obtain its light curve.  This
pulsar is an exciting new millisecond pulsar which is in a 2.38 hour
circular orbit about a 0.03 solar mass companion which eclipses the pulsed
radiation from the pulsar for 20 minutes each orbit.  The companion is only
the second eclipsing millisecond pulsar companion identified optically.
The observations were executed as scheduled, and no anomalies were noted.

   1.13 Completed Three Sets of WF/PC-2 6887 (A Photometric Search for
Faint Companions to Nearby Stars)

       The WF/PC-2 was used to make photometric search observations of the
nearby stars HD10700, G208-44-5 and L726-8-A in order to look for possible
companions.  The technique involves use of the Planetary Camera with wide
band pass filters to photometrically measure for the presence of resolved
dark companions.  The observations were executed as scheduled, and no
anomalies were noted.

   1.14 Completed Two 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.

   1.15 Completed Eight 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 none in parallel with
the prime science observations.  The procedure was completed as scheduled,
and no anomalies were noted.

   1.16 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 of PKS2247+14 will remedy this situation by
undertaking redder, line-free observations of our three matched AGN
samples.  The proposal completed with no reported problems.

   1.17 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 instrument is prime.  The observations were
completed as scheduled, and no anomalies were reported.

   1.18 Completed NIC/1/2/3 7729 (NICMOS Short One Orbit Parallel)

       The Near Infrared Camera (Cameras One, Two and Three) was used to
obtain "JHK" imaging of sky regions while another instrument was prime.
These observations were  part of the short NICMOS one orbit parallel
program.  The observations were executed as scheduled, and no anomalies
were noted.
