PERIOD COVERED:  0000Z (UTC) 11/19/98 - 0000Z (UTC) 11/20/98

Daily Status Report as of 324/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed Three Sets of WF/PC-2 7713 (WF/P-2 Cycle 7 Supplemental
Darks pt3/3)

       The WF/PC-2 was used to make supplemental dark calibration images.
This dark calibration program obtains three dark frames every day to
provide data for monitoring and characterizing the evolution of hot pixels.
The observations were completed as planned, and no anomalies were noted.

   1.2 Completed Eleven Sets of NIC/1/2/3 7963 (Darks: Warming Up)

       The Near Infrared Camera (Cameras One, Two and Three) was used to
monitor the detector dark current during the interval between the end of
science observations and the exhaustion of cryogen and subsequent warming
of the dewar to > 100K.  The observations were completed as planned, and no
anomalies were noted.

   1.3 Completed STIS/CCD 7948 (CCD Dark and Bias Monitor -- Cont. to Dec. 98)

       The Space Telescope Imaging Spectrograph (CCD) was used to measure
CCD dark current and bias rates for the two supported amplifier settings
{GAIN=1 and GAIN=4} in order to gather data for making superdarks and
superbiases.  The data will be used to track the growth of hot pixels on
the CCD in general and within the various target acquisition apertures
specifically.  The observations were executed as scheduled, and no
anomalies were noted.

   1.4 Completed WF/PC-2 8088 (Cosmological Parameters Omega and Lambda
from High-Z Type Ia Supernovae - DD)

       The WF/PC-2 was used to make observations of a high-Z supernova in
order to determine the cosmological parameters Omega and Lamda.  The
observations were executed as scheduled, and no anomalies were noted.

   1.5 Completed Four Sets of NIC/1/2/3 7961 (Flats: Warming Up)

       The Near Infrared Camera (Cameras One, Two and Three) was used to
monitor the flat fields during the interval between the end of science
observations and the exhaustion of cryogen and subsequent warming of the
dewar to > 100K.  These flats will provide a monitor for particulate
comtamination and detector lateral position {from the coronagraphic spot
and FDA vignetting}.  The proposal completed with no reported problems.

   1.6 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.

   1.7 Completed WF/PC-2 7387 (T-Tauri Star Snapshot Survey)

       The WF/PC-2 was used to make observations of the variable star
UX-Tau as part of a T-Tauri class star survey.  The observations were
executed as scheduled, and no anomalies were noted.

   1.8 Completed WF/PC-2 6664 (Stellar Ages in M 32: Exposing the Conspiracy)

       The WF/PC-2 was used to make observations of the galaxy NGC-221
(a.k.a., M-32) to study the stellar ages of its stars.  Accurate periods
and luminosities will be obtained of its RR Lyrae variable stars.  The
observations were executed as scheduled, and no anomalies were noted.

   1.9 Completed Two Sets of STIS/CCD 7912 (STIS Parallel Archive Proposal
- Nearby Galaxies - Imaging and Spectroscopy)

       The Space Telescope Imaging Spectrograph (CCD) was used to make
parallel observations of nearby galaxies.  This survey will be useful to
study the star formation histories, chemical evolution, and distances to
these galaxies.  These data will be placed immediately into the Hubble Data
Archive.  The observations were completed as scheduled, and no problems
were reported.

   1.10 Completed Seven Sets of STIS/CCD 8062 (POMS Test Proposal: STIS
Non-Scripted Parallel Proposal Continuation)

       The Space Telescope Imaging Spectrograph (CCD) was used to make high
galactic latitude observations taken in parallel with the prime science
observations.  The observations were completed as planned, and no problems
were reported.

   1.11 Completed WF/PC-2 6834 (Lenses, Mirrors, and HST: IRAS
FSC10214+4724 Under a Compound Microscope)

       The WF/PC-2 was used to make observations of IRAS FSC10214+4724.
Our existing WF/PC-2 images using filter F814W provides compelling evidence
that the this object which is at redshift of 2.3 and is gravitationally
lensed.  The observations were completed as planned, and no anomalies were
reported.
