PERIOD COVERED:  0000Z (UTC) 01/07/99 - 0000Z (UTC) 01/08/99

Daily Status Report as of 008/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed Two 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 Twelve Sets of NIC/1/2/3 8093 (DARKs: Warming Up - Part II)

       The Near Infrared Camera (Cameras One, Two and Three) was used to
make a series of dark calibration observations.  The purpose of this
proposal is 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.  (See 2.3)

   1.3 Completed WF/PC-2 8059 (POMS Test Proposal: WF-2 Targeted Parallel
Archive Proposal)

       The WF/PC-2 was used to make observations in parallel with the prime
science observations.  The parallel opportunities available with WF/PC-2 in
the neighborhood of bright galaxies are treated in a slightly different way
from the normal pure parallels.  Local group galaxies offer the opportunity
for a closer look at young stellar populations.  The observations were
completed as planned, and no anomalies were reported.

   1.4 Completed WF/PC-2 8090 (POMS Test Proposal: WF-II parallel archive
proposal continuation)

       The WF/PC-2 was used in the parallel mode to make some low galactic
latitude archive observations.  The program will be used to take parallel
images of random areas of the sky.  The observations were executed as
scheduled, and no anomalies were noted.

   1.5 Completed WF/PC-2 8061 (POMS Test Proposal: WF-II Backup Parallel
Archive Proposal)

       This is a POMS test proposal designed to simulate scientific plans.
The proposal was executed as planned, and no anomalies were reported.

   1.6 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.

   1.7 Completed WF/PC-2 6354 (Measuring Luminosity Evolution in Z = 0.3
Field Galaxies)

       The WF/PC-2 was used to make snapshot observations of the galactic
cluster Gal-Cluster-0734 located at a distance of Z = 0.3.  The targets
were drawn from a much larger pool of galaxies for which the internal
kinematics have been measured from an extensive ground based program.  The
observations were executed as scheduled, and no anomalies were noted.

   1.8 Completed Five Sets of STIS/CCD 8091 (POMS Test Proposal: STIS
Non-Scripted Parallel Proposal Continuation [10[III)

       The Space Telescope Imaging Spectrograph (CCD) was used to make high
galactic latitude, non-scripted, parallel observations.  The observations
were completed as planned, and no anomalies were noted.

   1.9 Completed WF/PC-2 7376 (Understanding Halo Microlensing and Variable
Stars in M31: 1} Snapshot Survey of Candidates)

       The WF/PC-2 was used to make observations of the galaxy M-31-Lens
system #5 to help understand its halo microlensing and Variable Stars.  Six
microlensing candidates affecting stars in M31 and presumably due to
sub-solar-mass MACHOs are being studied.  Simultaneously we can explored
the stellar population in the relatively unexplored disk/bulge transition
via its variable stars, luminosity function and color-magnitude diagram.
The observations were executed as scheduled, and no anomalies were
reported.

   1.10 Completed WF/PC-2 6560 (Mapping an Optical Einstein Ring)

       The WF/PC-2 was used to make observations of galaxy GAL-004942 in
order to study its Einstein gravitational ring system.  Observations of
gravitationally lensed Einstein-ring images provide a dramatic improvement
in our ability to constrain the properties of lensing mass distributions
and the structure in the extended sources.  The observations were executed
as scheduled, and no anomalies were noted.

   1.11 Completed Four Sets of NIC/1/2/3 8083 (FLATs: Warming Up -
continuation)

       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.  (See 2.3)

   1.12 Completed Five Sets of STIS/CCD 8084 (POMS Test Proposal: STIS
Non-Scripted Parallel Proposal Continuation)

       The Space Telescope Imaging Spectrograph (CCD) was used to make
non-scripted parallel high galactic latitude observations as part of POMS
test proposal.  The observations were executed as scheduled, and no
anomalies were noted.

   1.13 Completed FOC/96 6350 (FOC spectroscopy of BALQSOs)

       The Faint Object Camera (f/96) was used to make ultraviolet
spectrographic images of BALQSO 1246-0542 which is known to show broad
emission lines from abundant ions.  This will help us improve our knowledge
of these BAL class objects.  The observations were executed as scheduled,
and no anomalies were noted.

   1.14 Completed Two Sets of NIC/2/3 8082 (NICMOS Pure Parallel Fall 98)

       The Near Infrared Camera (Cameras Two and Three) was used to make
pure parallel observations while another instrument is prime.  (See 2.3)

   1.15 Completed WF/PC-2 7434 (The Supernova Intensive Study)

       The WF/PC-2 was used to continue the long-term project on supernovae
by observing SN1987A.  HST can make unique contributions to understanding
supernovae, as has been demonstrated through this program in past years,
and now STIS and NICMOS offer new opportunities for deepening this
investigation.  The aim of the proposal is to explore the UV emission from
supernovae, exploit the spatial resolution of HST and press the late-time
observations of supernovae into uncharted territory.  The observations were
completed as planned, and no anomalies were reported.

   1.16 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.

   1.17 Completed NIC/2/3 8063 (NICMOS Pure Parallel Sponge - Backup)

       The Near Infrared Camera (Cameras Two and Three) was used to make
observations taken in parallel with the prime science observations.  This
proposal is PRE-the new FOM default.  (See 2.3)

   2.3 Operations Notes:

        As noted in the 1/7/99 report, the NICMOS filter wheels have been
inhibited.  The proposals in this week's SMS will execute.  The instrument
will transition to the SAA operate mode at the beginning of the day 011
SMS, and will remain in that mode until SM3.

       Using ROP SR-1, the SSR EDAC error counter was cleared twice.

       As documented in HSTAR 6868, the STIS MCE-1 reset at 007/124741Z
while in an SAA interval and while the low voltage was on.  The STIS flight
software error counter and the error flag were cleared at 007/130134Z.
Recovery was accomplished via SMS commanding at 008/01435Z when MAMA-1 was
transitioned to high voltage.

       The NSSC-1 status buffer was dumped per ROP NS-3.

3.0 SIGNIFICANT FORTHCOMING EVENTS:

       Continuation of normal science observations and calibrations.
