                       DAILY REPORT #2258

PERIOD COVERED:  0000Z (UTC) 11/24/98 - 0000Z (UTC) 11/25/98

Daily Status Report as of 329/0000Z

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 Twelve 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.  As described in HSTAR 6784 and yesterday's report,
the acquisition for the second and third iterations of this proposal
defaulted to fine lock backup on one FGS only.  Otherwise, the observations
were completed as planned, and no further anomalies were noted.

   1.3 Completed Two Sets of 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 FOC/96 6350 (FOC spectroscopy of BALQSOs)

       The Faint Object Camera (f/96) was used to make ultraviolet
spectrographic images of BALQSO 1011+0906 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.

   1.5 Completed Eight Sets of STIS/CCD 8057 (STIS CCD Performance Monitor
{continued})

       The Space Telescope Imaging Spectrograph (CCD) was used to monitor
to overall CCD performance.  As described in HSTAR 6784 and yesterday's
report, the acquisition for the second iteration of this proposal defaulted
to fine lock backup on one FGS only.  Otherwise, the observations were
executed as scheduled, and no further anomalies were noted.

   1.6 Completed WF/PC-2 7344 (Witnessing the Birth of Radio Galaxies:
WF/PC-2 & NICMOS Observations of CSOs)

       The WF/PC-2 was used to make observational images of the cores of
bright, nearby galaxy (Compact Symmetric Object) CSO 4C31.04 in order to
try to witness the birth of a radio galaxy.  Only HST can image these
galaxies at the same size scale of the CSO itself, also allowing us to
search for nuclear structures aligned with the radio source in this
formative stage.  As described in HSTAR 6784 and yesterday's report, the
acquisition for this proposal defaulted to fine lock backup on one FGS
only.  Otherwise, the observations were completed as planned, and no
further anomalies were reported.

   1.7 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}.  As described in HSTAR 6784 and yesterday's report,
the acquisition for the first iteration of this proposal defaulted to fine
lock backup on one FGS only.  Otherwise, the proposal completed with no
other reported problems.

   1.8 Completed Nine 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.  As described in HSTAR 6784 and yesterday's report, the
acquisition for the first iteration of this proposal defaulted to fine lock
backup on one FGS only.  Otherwise, the observations were completed as
planned, and no further problems were reported.

   1.9 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
3C29.0.  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.

   1.10 Completed WF/PC-2 6626 (Imaging of Z>1 - Massive Star Forming Galaxies)

       The WF/PC-2 was used to make observations of the massive star
forming galaxy SSA22W which is known to have a redshift of Z>1.0.  The
central regions of the galactic strips have already been imaged with HST
and the current observations are to cover the samples required to finish
the set.  The observations were executed as scheduled, and no anomalies
were noted.

   1.11 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.

   1.12 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 IRASFSC102.  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.

   1.13 Completed Four 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.

   2.3 Operations Notes:

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

       Two TTRs were written: one for six data hits and the other for two
data inversions.

       HSTAR 6786 describes a NICMOS single bit error that occurred at
328/214956Z.  The NICMOS internal log was dumped at 328/2220Z.  HSTAR 6788
documents three additional NICMOS single bit errors occurring at
328/231256Z, at 329/000155Z, and at 329/003255Z.  After the latest
occurrence, the ground system limit was raised to 53.
