PERIOD COVERED:  0000Z (UTC) 01/15/98 - 0000Z (UTC) 01/16/98

Daily Status Report as of 016/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed STIS/CCD 7802 (Daily Darks to Update Acquisition Bad Pixel
Table)

       The Space Telescope Imaging Spectrograph (CCD) was used to make
calibration observations to obtain daily darks to update the acquisition
bad pixel table.  These darks are intended to identify hot pixels for
update to the acquisition on-board FSW hot 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 NIC/3 7696 (NICMOS Grism Absolute Sensitivity)

       The Near Infrared Camera (Camera Three) was used to make some NICMOS
grism absolute sensitivity calibration images by making observations of the
white dwarf star G191-B2B.  The observations were completed as planned, and
no problems were reported.

   1.3 Completed STIS/CCD 7711 (STIS CCD G750L Fringing Flats.)

       The Space Telescope Imaging Spectrograph (CCD) was used to
investigate and monitor the STIS CCD flat-field fringing in the G750L
grating at its nominal wavelength setting {7751A}.  WAVECALs were also
taken at the same gain and wavelength setting.  Typical S/N = 100 for each
integration, and gain = 4 on each.  The observations were executed as
scheduled, and no anomalies were noted.

   1.4 Completed WF/PC-2 7622 (WF/PC-2 Cycle 7 Internal Monitor)

       The WF/PC-2 was used to make a set of Cycle 7 internal monitoring
calibration measurements.  A variety of internal exposures are obtained in
order to provide a monitor of the integrity of the CCD camera electronics
in both bays {gain 7 and gain 15}, a test for quantum efficiency in the
CCDs, and a monitor for possible buildup of contaminants on the CCD
windows.  A bias calibration and an internal flat calibration image were
also taken.  The observations were executed as scheduled, and no anomalies
were noted.

   1.5 Completed Two Sets of NIC/1/2/3 7456 (Water in Protoplanetary Disks)

       The Near Infrared Camera (Cameras One, Two and Three) was used to
make observations of the protoplanetary disk around the star GO-Tau to
search for water in its disk.  This survey will be the first to take a
detailed look at the gas phase properties of pre-main-sequence disks at AU
distances.  The observations were completed as scheduled, and no anomalies
were reported.

   1.6 Completed Four Sets of NIC/1/3 7813 (NIC/3 HDF Darks)

       The Near Infrared Camera (Cameras One and Three) was used to make
internal dark calibration images which will be used when processing the
Hubble Deep Field images during the first NICMOS Camera Three campaign.
The observations were executed as scheduled, and no anomalies were noted.

   1.7 Completed Two Sets of NIC/1/2/3 7322 (The IMF Below 1 Msun in Young
Clusters: 1.9micron Water Band Imaging of IC348)

       The Near Infrared Camera (Cameras One, Two and Three) was used to
make observations of cluster IC348.  This study will be the first to obtain
spectral types for a young cluster population complete to K=16, and thereby
quantify, to unprecedentedly high precision, the IMF below 1M{sun} in young
clusters.  The observations were executed as scheduled, and no anomalies
were reported.

   1.8 Completed Two Sets of NIC/1/2/3 7215 (Line and Continuum
Investigation of NGC 1068 and NGC 4151)

       The Near Infrared Camera (Cameras One, Two and Three) was used to
make observations of the bright, nearby AGNs NGC-1068 and NGC-4151.  This
program studies the high resolution morphology of the continuum and line
emission in these two galaxies.  The continuum studies will determine the
stellar and non-stellar luminosity distribution in the galaxies.  The
observations were executed as scheduled, and no anomalies were noted.

   1.9 Completed NIC/3 7815 (NICMOS Earth Flats)

       The Near Infrared Camera (Camera Three) was used to make a Earth
flat field calibration image.  This proposal obtains a series of earth
flats for a subset of narrow and medium band NIC/3 filters in advance of
the NIC/3 campaign.  These flats will be used to generate the master flats
for narrow-band filters and to determine the OTA illumination pattern as a
function of wavelength.  The observations were completed as planned, and no
anomalies were reported.

   1.10 Completed Two Sets of NIC/3 7816 (NIC/3 Photometric Zero Point)

       The Near Infrared Camera (Camera Three) was used to make
observations of standard stars GD153-Cal and P177D-Cal in order to study
the zero point flux for a set of filters.  The NIC/3 intra-pixel
sensitivity will also be measured.  The observations were executed as
scheduled, and no anomalies were noted.

   1.11 Completed NIC/1/2/3 7173 (Emission Line Imaging of Extragalactic Jets)

       The Near Infrared Camera (Cameras One, Two and Three) was used to
make emission line imaging of the extragalactic jet in galaxy M87.  If a
jet emanating from a galactic nucleus collides with an interstellar cloud,
the jet will presumably induce shocks in the cloud.  The observations were
completed as planned, and no anomalies were reported.
