PERIOD COVERED:  0000Z (UTC) 01/05/99 - 0000Z (UTC) 01/06/99

Daily Status Report as of 006/0000Z

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 Nine 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.  The observations were executed
as scheduled, 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 Three 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.

   1.5 Completed STIS/MA1 7471 (STIS Snapshot Search for UV-bright High
Redshift Quasars)

       The Space Telescope Imaging Spectrograph (MA1) was used to make
ultraviolet observations of the bright high redshifted quasar HS1140+350.
This quasar shows no signs of strong absorption in its optical spectra, and
its He-II Lambda 304 A0 line is accessible with HST.  A wavelength
calibration image was also taken.  The observations were executed as
scheduled, and no anomalies were noted.

   1.6 Completed FOC/96 6932 (FOC Cycle 6 UV Flatfield)

       The Faint Object Camera (f/96) was used to make ultraviolet
observations of the FFT9 region of the Orion Nebula.  An internal flat and
a dark calibration image were also taken.  The observations were executed
as scheduled, and no anomalies were noted.

   1.7 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.  The
observations were executed as scheduled, and no anomalies were noted.

   1.8 Completed Three Sets of STIS/CCD 8091 (POMS Test Proposal: STIS
Non-Scripted Parallel Proposal Continuation 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 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.

   1.10 Completed Two Sets of 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.  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.  The observations were executed as scheduled, and no
anomalies were noted.

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

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

   1.13 Completed WF/PC-2/NIC/3 7382 (The Star-Formation History of the
Large Magellanic Cloud)

       The WF/PC-2 and the Near Infrared Camera (Camera Three) were used to
make observations of the disk of the Large Magellanic Cloud (LMC-BAR-3).
These data will enable us to quantitativly study the intermediate to
low-mass stellar populations and the star-formation history of the LMC.
The observations were executed as scheduled, and no anomalies were noted.

   1.14 Completed WF/PC-2 6967 (Blue Continuum Snapshots of 3CR Radio -
Continued Galaxies)

       The WF/PC-2 was used to make observations of the radio galaxy
3C93.1.  Radio galaxies are an important class of extragalactic objects:
they represent one of the most energetic astrophysical phenomena; they may
be used as probes of their environments; and they are unique probes of the
early Universe.  The observations were completed as planned, and no
problems were reported.

   1.15 Completed STIS/CCD/NIC/1/2/3 7566 (Demographics of Nuclear Black Holes)

       The Space Telescope Imaging Spectrograph (CCD) and the WF/PC-2 were
used to make observations of normal galaxy NGC-4486 to try and detect a
super massive black hole.  A dark and wavelength calibration images were
also taken.  The observations were executed as scheduled, and no anomalies
were noted.

2.0 FLIGHT OPERATIONS SUMMARY

   2.1 Guide Star Acquisitions:

                            Scheduled Acquisitions : 10
                                        Successful : 10

                          Scheduled Reacquisitions : 8
                                        Successful : 8

   2.2 FHST Updates:

                              Scheduled : 14
                             Successful : 14

   2.3 Operations Notes:

        Using ROP SR-1, the SSR EDAC error counter was reset three times.

       A TTR was written to document a data hit at 005/2244Z whe1198 minor
frames were missed.

       The CCS command activity concluded uneventfully at 005/2244Z.  All
test objectives were met with no problems.  Another period of CS commanding
will commence at approximately 006/1400Z.

       The latest analysis of NICMOS FPA temperatures indicate that the
warm-up rate on Camera-3 has increased to a rate of approximately 9 degrees
K per day, indicating that the thermal short has strengthened in the
Camera-3 baffle.  The saturation point of -78.1 degrees K is rapidly
approaching and should be reached this afternoon and evening. Procedures
are in place to inhibit the filter wheel commanding (probably this morning
between 006/1427Z and 006/1442Z) prior to when these parameters flag
out-of-limits.

       ESTR-2 was reconditioned at 006/0709Z per ROP RD-7.

3.0 SIGNIFICANT FORTHCOMING EVENTS:

       Continuation of normal science observations and calibrations.
