PERIOD COVERED:  0000Z (UTC) 12/30/97 - 0000Z (UTC) 01/05/98

Daily Status Report as of 005/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed Thirteen Sets of WF/PC-2 7621 (WF/PC-2 Cycle 7
Supplemental Darks PT1/3)

       The WF/PC-2 was used to make supplemental dark calibration images.
This set of calibrations is intended to obtain three dark frames every day
to provide data for monitoring and characterizing the evolution of hot
pixels.  During the twelfth iteration of this proposal, as mentioned in
2.1, the guide star acquisition defaulted to fine lock on one FGS only.
Otherwise, the observations were executed as scheduled, and no other
further anomalies were noted.

   1.2 Completed Ten Sets of WF/PC-2 7786 (Pure Parallel Archive Survey -
Continuation)

       The WF/PC-2 was used to make observations as part of an archival
survey program in which the images were taken in parallel with the prime
science observations.  These WF/PC-2 parallel observations were obtained in
the ultraviolet in a search for interesting objects.  The observations were
completed as planned, and no problems were reported.

   1.3 Completed NIC/2 7495 (Survey of Gravitational Lenses as Cosmological
Tools)

       The Near Infrared Camera (Camera Two) was used to make survey
observations of object Q1429-008 by obtaining deep, high-resolution images
in the optical and near IR in order to see if it is gravitational lenses
and could be used as a cosmological tool.  During a scheduled LOS at
364/0308Z-0322Z there was a guide star acquisition loss of fine lock at
0308-0316Z.  Fine lock backup was acquired on FGS-3 only.  HSTAR 6285 was
written.  Otherwise, the observations were executed as scheduled, and no
further anomalies were noted.

   1.4 Completed Three Sets of NIC/1/2/3 7249 (Line, Continuum,and
Polarimetric Observation of AFGL 437)

       The Near Infrared Camera (Cameras One, Two and Three) was used to
make line, continuum and polarimetric observations of AFGL-437.  The higher
spatial resolution of NICMOS will determine if this is the correct
component and measure the flows near the star as indicated by the direction
of the polarization vectors.  The observations were executed as scheduled,
and no anomalies were noted.

   1.5 Completed Two Sets of STIS/CCD 7635 (STIS CCD Hot Pixel Annealing)

       The Space Telescope Imaging Spectrograph (CCD) was used to test the
hot pixel annealing procedure.  The effectiveness of the CCD hot pixel
annealing process is assessed by measuring the dark current behavior before
and after annealing and by searching for any window contamination effects.
The observations were completed as planned, and no problems were reported.

   1.6 Completed FOC/96 6667 (The Far-UV Evolution of Elliptical Galaxies)

       The Faint Object Camera (f/96) was used to make far-ultraviolet (UV)
observations of a large elliptical A370-24 (near M-4).  The far-UV spectra
of nearby giant elliptical galaxies are characterized by a "UV rising
branch", which varies greatly in strength from galaxy to galaxy.  During a
scheduled LOS at 364/0312Z-0332Z there was a Guide Star Acquisition loss of
fine lick at 0326-0334Z. Fine Lock Backup was acquired on FGS 1 only.
HSTAR 6286 was written.  The observations were executes as planned, and no
problems were reported.

   1.7 Completed Sixteen Sets of NIC/2/3 7922 (New NICMOS Modified One
Orbit Parallel)

       The Near Infrared Camera (Cameras One and Two) was used to make one
orbit parallel observations.  This proposal obtains "JH" imaging, and G096
and G141 spectroscopy of sky regions when another instrument is prime.
STEP64 sequences are used and two dither positions are obtained for each
filter.  The observations were executed as scheduled, and no anomalies were
noted.

   1.8 Completed Seven Sets of 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.

   1.9 Completed WF/PC-2 6802 (Cosmology With the Medium Deep Survey)

       The WF/PC-2 was used to make observations taken in parallel with the
prime science observations as part of the Medium Deep Sky Survey.  The
observations were executed as scheduled, and no problems were reported.

   1.10 Completed Six Sets of WF/PC-2 7625 (WF/PC-2 Cycle 7 Earth Flats)

       The WF/PC-2 was used to make a series of Earth flat calibration
images.  These flat fields will allow mapping of the OTA illumination
pattern and will be used in conjunction with previous internal and external
flats to generate new pipeline superflats.  The observations were completed
as planned, and no anomalies were reported.

   1.11 Completed STIS/CC 7782 (STIS Non-Scripted Parallel Archive Proposal
- Half Orbit)

       The Space Telescope Imaging Spectrograph (CCD) was used for a
non-scripted parallel archive proposal (one-half orbit).  The observations
were executed as scheduled, and no anomalies were noted.

   1.12 Completed Ten Sets of STIS/CCD 7781 (STIS Non-Scripted Parallel
Archive Proposal - Full Orbit)

       The Space Telescope Imaging Spectrograph (CCD) was used for a
non-scripted parallel archive proposal (one full orbit).  The observations
were executed as scheduled, and no anomalies were noted.

   1.13 Completed S/C 5582 (FOC/48 Monthly Activation (Camera Section
Only): Cycle 4)

        This proposal was executed as scheduled, and no anomalies were noted.

   1.14 Completed NIC/1/2/3 7607 (NICMOS Photometric Monitoring Test)

       The Near Infrared Camera (Cameras One, Two, and Three) was used to
conduct a photometric monitoring test by making observations of standard
star P330E-Cal.  The standard star was observed with NIC1 & NIC2 at six
different wavelengths spanning the NICMOS wavelength range.  The
observations were completed as planned, and no anomalies were reported.

   1.15 Completed Three Sets of NIC/2 7420 (A Near-Infrared Search for Very
Low Mass Companions to Stars Within 10 Parsecs of the Sun)

       The Near Infrared Camera (Camera Two) was used to make searching
observations for very low mass companions to variable stars LHS46, LHS411
and LHS11261.  These stars are known to be within 10 parsecs of the Sun.
The observations were executed as scheduled, and no anomalies were noted.

   1.16 Completed Two Sets of 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.

   1.17 Completed Two Sets of NIC/2 7219 (Ultraluminous Infrared Galaxies)

       The Near Infrared Camera (Camera Two) was used to make observations
of the ultraluminous infrared galaxies NGC-5253 and 14348-1447.  The
luminous IRAS galaxies are probably powered by nuclear starbursts and/or
central AGNs: many of these systems exhibit evidence of recent galactic
interaction or merging. The observations were completed as planned, and no
problems were reported.

   1.18 Completed NIC/1/2/3 7425 (Gravitational Lensing Enhanced NICMOS
Imagery of a Young, Rapidly Evolving Faint Blue Galaxy)

       The Near Infrared Camera (Cameras One,Two and Three) was used to
make observations of the galactic cluster GAL-CLUS-0142.  Previous WF/PC-2
observations of this gravitational lens system show a faint blue galaxy is
multiple-imaged by a foreground rich galaxy cluster have allowed the
reconstruction of the source.  It displays a spectacular ring-like
morphology with several bright knots and a dark center that strongly
suggests vigorous star formation and rapid evolution.  The observations
were completed as planned, and no problems were reported.

   1.19 Completed WF/PC-2 6659 (A Search For Superplanets Around Weak T-
Tauri Stars)

       The WF/PC-2 was used to make observations in the one micron band of
the T-Tauri class star HBC419 in order to search for superplanets.  Weak
T-Tauri class stars are thought to have dissipated their circumstellar
disks recently, possibly by forming planetary systems.  The observations
were completed as planned, and no anomalies were reported.

   1.20 Completed WF/PC-2 7916 (The Nucleus of Comet 9P/Tempel 1)

       The WF/PC-2 was used to make observations of the nucleus of comet
9P/Tempel 1 during  opposition in order to determine the properties of its
nucleus {size, shape, and rotational period} in support of the NASA
DS4/Champollion mission.  As detailed in 2.1, one of the acquisiitions for
this proposal defaulted to fine lock on one FGS-1 only.  Otherwise, the
observations were completed as planned, and no furtherproblems were
reported.

   1.21 Completed STIS/CCD 7302 (STIS Observations of Eta-Carinae: Good
Spectral Coverage at Last)

       The Space Telescope Imaging Spectrograph (CCD) was used to make
observations of Eta-Carinae.  Eta-Carinae is uniquely significant for
several astrophysical topics.  The FOS and GHRS have produced excellent
spectroscopic results on this object, solving some questions while opening
some new ones.  However, for instrumental reasons their spectral coverage
of Eta-Car has been inadequate.  A wavelength calibration image was also
taken.  The observations were completed as scheduled, and no anomalies were
reported.

   1.22 Completed Three Sets of NIC/2 7331 (Near-IR Properties of the
Bulges of Spiral Galaxies)

       The Near Infrared Camera (Camera Two) was used to make infrared
observations of the bulge in spiral galaxies NGC-1800 and ESO548G29.
Near-IR data at HST resolution are essential for correcting for the effect
of dust and will enable us to derive robust nuclear properties for the
sample.  The observations were executed as scheduled, and no anomalies were
noted.

   1.23 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.

   1.24 Completed WF/PC-2 7427 (Saturn's Rings)

       The WF/PC-2 was used to make imaging observations of both the east
and west apsides of Saturn's rings.  Saturn's rings are a unique dynamical
laboratory and continue to present challenging problems which require
additional data to attack.  The observations were completed as planned, and
no problems were reported.

   1.25 Completed NIC/2 7330 (The Fueling of Active Nucleii: A NICMOS
Snapshot Survey)

       The Near Infrared Camera (Camera Two) was used to probe the dark
matter distribution of NGC-788, far from the center, by observing
intervening absorption from the MgII doublet (lambda 2800) in the spectrum
of one background QSO located in a geometrically optimal position.  HST
observations are required because this feature is in a wavelength range not
accessible from the ground, and the QSO magnitudes and expected strength of
absorption make IUE observations unfeasible.  The proposal completed as
expected with no anomalies.

   1.26 Completed FGS 7598 (Long Term Stability of Transfer Scan Mode in FGS-3)

       The Fine Guidance Sensor #3 was used to make observations of
standard star UPGREN69 in order to study the long term stability of the
transfer scan mode order to study the long term stability of that mode.
The observations were completed as planned, and no problems were reported.

   1.27 Completed STIS/CCD 7672 (STIS CCD Sensitivity Monitor)

       The Space Telescope Imaging Spectrograph (CCD) was used to make
observations of standard star AGK+871D266 in order to monitor the
sensitivity of each CCD grating mode to detect any change due to
contamination or other causes.  A wavelength calibration image was also
taken.  The observations were completed as scheduled, and no anomalies were
noted.

   1.28 Completed WF/PC-2 7386 (A Snapshot Survey of Nova Shells)

       The WF/PC-2 was used to make observational images of the super nova
shell QU-Vul in order to detect and measure its expanding gaseous shell.
These observations will trace the distribution of hot and cool gas in the
nova shells, and show their degree of inhomogeneity on both large and small
scales.  The observations were completed as scheduled, and no problems were
noted.

   1.29 Completed Two Sets of NIC/2 7220 (Imaging of Quasar Host Galaxies)

       The Near Infrared Camera (Camera Two) was used to make direct
imaging observations of the host galaxy for the broad absorption line
quasar QSO1038+05.  The observations were completed as planned, and no
anomalies were reported.

   1.30 Completed NIC/1/2 7690 (NICMOS Pointed Super Flats)

       The Near Infrared Camera (Cameras One and Two) was used to make
super flat field calibration observations.  The observations will be used
to build high signal/noise ratio NICMOS flat fields for the different
filters.  A dark calibraion image was also taken.  The observations were
executed as scheduled, and no anomalies were noted.

   1.31 Completed FGS 7597 (Long Term Stability of Transfer Scan Mode in
FGS-1R)

       The Fine Guidance Sensor-1R was used to make observations of the
standard star UPGREN69 in order to study the long term stability of the
transfer scan mode.  The observations were executed as scheduled, and no
anomalies were noted.

   1.32 Completed WF/PC-2 7497 (WF/PC-2 Observations of Astrophysically
Important Visual Binaries)

       The WF/PC-2 was used to make observations of the visual binary
variable sat system MU Cas.  This system is a famous metal-deficient G
dwarf for which accurate masses will lead to the star's helium content with
cosmological implications.  The observations were completed as planned, and
no anomalies were reported.

   1.33 Completed NIC/1/2/3 7415 (Infrared Spectroscopic Study of the Very
Low Mass Triple System LHS 1070)

       The Near Infrared Camera (Cameras One, Two and Three) was used to
make spectrographic observations of the very low mass triple star system
VB-10 (a.k.a., LHS1070-B).  Accurate stellar parameters for the LHS 1070
system will provide a unique opportunity to better determine the poorly
understood transition region between low mass stars and brown dwarfs, while
yielding solid constraints for stellar models.  The observations were
executed as scheduled, and no anomalies were noted.

   1.34 Completed STIS/CCD 7312 (Investigating Volatile Depletion in Two
Periodic Comets: 2P/Encke and 103P/Hartley 2)

       The Space Telescope Imaging Spectrograph (CCD) was used to make
images of the periodic comet Hartley 2 to investigate its volatile
depletion.  Current theories predict that the near-surface regions of
cometary nuclei should become increasingly devolatilized during successive
passages through the inner solar system.  A wavelength calibration image
was also taken.  The observations were executed as scheduled, and no
anomalies were noted.

   1.35 Completed STIS/CCD 7807 (HDF Test Exposures)

       The Space Telescope Imaging Spectrograph (CCD) was used to make a
series of Hubble Deep Field test exposures.  This is a test exposure to
ensure good guide star selection and proof of concept.  The observations
were completed as planned, and no problems were reported.

   1.36 Completed WF/PC-2 6526 (Distance, Proper Motion and Colors of the
Vela Pulsar.)

       The WF/PC-2 was used to make ultraviolet observations of the proper
motion and colors of the pulsar (STAR-0835) which is located in the Vela
Nebula.  This is the only isolated neutron star known to pulsate in the
optical domain.  Although the optical counterpart of the Vela Pulsar has
been identified since 1977, nothing is known about its ultraviolet emission
beyond a limited, ground based point in the U band.  The observations were
executed as scheduled, and no anomalies were noted.

   1.37 Completed Three Sets of STIS/CCD 7783 (STIS Parallel Science)

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

   1.38 Completed Three Sets of FGS 7681 (FGS-3 Red Transfer Function
Reference Calibration)

       The Fine Guidance Sensor-3 (the astrometer) was used to make
observations of HD233877, Lat-Col-1A and HD28484 in order to perform a red
transfer function reference calibration through the pupil, clear and
neutral density filters at the center of the FGS-3 field of view.  The
observations were completed as planned, and no anomalies were reported.

   1.39 Completed STIS/CCD 7333 (STIS Images of 48 Damped Ly-Alpha Galaxies)

       The Space Telescope Imaging Spectrograph (CCD) was used to make
observations of the damped Lyman-Alpha galaxy Q0841+129.  This study will
unify absorption-line studies, and faint galaxy imaging studies, thereby
allowing a detailed treatment of the history of star formation, gas
consumption, chemical enrichment, and assembly in the population of
galaxies.  The observations were completed as planned, and no problems were
reported.

   1.40 Completed NIC/1/2/3 7421 (The Relation Between Quasar Luminosity
and Host Galaxy Mass)

       The Near Infrared Camera (Cameras One, Two, and Three) was used to
obtain ground-based, near-infrared imaging of nearby quasars which have
indicated a relation between the luminosity of the nucleus and the luminous
mass of the host galaxy.  The observations completed as planned, with no
reported problems.

   1.41 WF/PC-2 6549 (Calibration of Nearby Type Ia Supernovae as Standard
Candles: NGC 3627 and SN 1989B)

       The WF/PC-2 was used to make observations of the Type Ia supernova
SN 1989B which is located in galaxy NGC-3627.  The experiment is designed
to determine the mean absolute magnitude M{max} of the B and V of SNe Ia,
and how large the dispersion is about this mean.  The observations were
completed as planned, and no problems were reported.

   1.42 Completed NIC/1/2/3 7608 (NICMOS Focus Monitoring)

       The Near Infrared Camera (Cameras One, Two, and Three) was used to
determine and monitor the optimal focus and tilt settings for all three
NICMOS cameras by making images of the cluster NGC-3603.  This proposal is
built to run NIC1/2/3 sweeps on a 2-week basis.  The observations completed
without incident with no reported anomalies.

   1.43 Completed WF/PC-2 6431 (Determination of the Extragalactric
Distance Scale)

       The WF/PC-2 was used to make observations of the galaxy NGC-3319 to
be used in measuring the periods of Cepheid variable stars within this
galaxy.  This will allow for a more accurate estimate of the distances to
these galaxies through the period-luminosity relation for the Cepheid
stars.  The observations were executed as scheduled, and no anomalies were
noted.

   1.44 Completed WF/PC-2 7409 (Resolving sdB Binary Systems)

       The WF/PC-2 was used to make observations to try to resolve the sdB
class binary system Star-12560.  This is a continuation of the approved
Cycle 6 Proposal No. 6351, which for unlucky circumstances did not succeed
to obtain any data until 8/30/96.  The observations were completed as
scheduled, and no anomalies were reported.

   1.45 Completed NIC/1/2 7823 (Saturn's Haze Properties in the Near Infrared)

       The Near Infrared Camera (Camera One and Two) was used to make
observations of the planet Saturn in order to study its haze in the near
infrared.  Our analysis of WF/PC-1 and WF/PC-2 images of Saturn yielded
powerful constraints on Saturn's vertical haze structure due to the
availability of measuring center-to-limb variation very close to the limb
of Saturn's disk.  As mentioned in 2.1, the guide star acquisition for this
proposal defaulted to fine lock on one FGS only.  Otherwise, the
observations were executed as scheduled, and no further problems were
noted.

   1.46 Completed WF/PC-2 7377 (Dwarf Elliptical Galaxy Snapshot Survey II)

       The WF/PC-2 was used to make observations of the dwarf elliptical
galaxy VCC328 as part of Snapshot Survey II.  This survey will provide
important information on the globular cluster systems of such galaxies and
the properties of their cores and nuclei.  The observations were completed
as planned, and no anomalies were reported.

   1.47 Completed NIC/1/2/3 7896 (A NIR Snapshot Survey of Ultraluminous IR
Galaxies)

       The Near Infrared Camera (Cameras One, Two and Three) was used to
make snapshot survey observations of the ultraluminous infrared galaxy
QDOTULIR06.  Nearly all of these galaxies show evidence for a recent tidal
interaction, and we will search for evidence of the merger progenitors near
the center of each galaxy, a task made significantly easier with NIR
imaging.  The observations were completed as planned, and no anomalies were
noted.

   1.48 Completed WF/PC-2 6887 (A Photometric Search for Faint Companions
to Nearby Stars)

       The WF/PC-2 was used to make a photometric search observations of
the nearby star HD16160 in order to look for possible companions.  The
technique involves use of the Planetary Camera with wide band pass filters
to photometrically measure for the presence of resolved dark companions.
The observations were executed as scheduled, and no anomalies were noted.

   1.49 Completed STIS/CCD/MA1 7755 (Fundamental Parameters of White Dwarfs
in Close Binaries with Late-Type Stars)

       The Space Telescope Imaging Spectrograph (CCD and MA1) was used to
make observations of the binary star system WD0232+035 which is made up of
a white dwarf and a late-type star.  The properties of the present-day
binary are dictated by the efficiency of the momentum transfer leading to
orbital shrinkage and mass ejection from the system.  Little is known of
this process.  The observations were completed as planned, and no anomalies
were reported.

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

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

   1.51 Completed STIS/MA1/MA2 7657 (STIS Spectroscopic and Imaging
Sensitivity, MAMA)

       The Space Telescope Imaging Spectrograph (MA1 and MA2) was used to
make observations of GD71 in order to study the spectroscopic and imaging
sensitivity.  Sensitivity measurements are done for all primary tilts of
the gratings and the prism used with the MAMAs, except for the G140L and
G230L gratings.  Imaging sensitivity measurements are done with all
apertures, including a neutral density filter.  A wavelength and a dark
calibration images were also taken.  The observations were executed as
scheduled, and no anomalies were noted.

   1.52 Completed Two Sets of  NIC/2 7808 (NICMOS Coronagraphic Hole
Location Test)

       The Near Infrared Camera (Camera Two) was used to make an
observational test of the location of the coronagraphic hole by observing
object NGC-2264.  This test is designed to effectively test the NICMOS
coronagraph hole location flight software.  Observations will be taken with
and without a bright object in the acquisition box as well as at a
different roll angle.  At each of these tests, the memory will be
downloaded for the acquisition images.  A dark calibration image was also
taken.  The observations were executed as scheduled, and no anomalies were
noted.

   1.53 Completed STIS/CCD 7660 (STIS to FGS Alignment Check)

       The Space Telescope Imaging Spectrograph (CCD) was used to make
observations of object NGC-188 as part of an FGS alignment check to
re-verify the STIS aperture and slit locations, and check the
transformation of the STIS CCD detector reference frame to the FGS
reference frame, after the FGS-FGS update.  The observations were completed
as planned, and no anomalies were reported.

2.0 FLIGHT OPERATIONS SUMMARY:

   2.1 Guide Star Acquisitions:

                            Scheduled Acquisitions : 66
                                        Successful : 66

       The acquisition at 365/200550Z failed to fine lock on FGS-1 only.
HSTAR 6291 was written.  The proposal described in 1.20 may have been
affected.

       As detailed in HSTAR 6296, the acquisition at 004/011659Z failed to
fine lock on FGS-1.  The proposals desccibed in 1.1 and 1.45 may have been
affected.

       There was a loss of lock at 004/102014Z near the EODAY transition.
HSTAR 6297 was written.  There was no science impact.

                          Scheduled Reacquisitions : 31
                                        Successful : 31

   2.2 FHST Updates:

                              Scheduled : 129
                             Successful : 127

       Per HSTAR 6292, the full maneuver updates at 002/001558Z and
002/001843Z, using FHSTs 1 and 3, failed.  The following acquisition was
successful, however.

   2.3 Operations Notes:

       The STIS bad pixel table was uplinked at 364/2320Z.

       Per operations note 387, the NICMOS EDAC single bit error counter
high limit was changed to "1" at 365/2144Z.  This limit will remain until
HSTAR 6290 (when the limit was exceeded) is fully investigated.

       As indicated in operations note 388, the upper limit for ETANLK1T
was raised 0.5 degrees C, when that limit was exceeded (see HSTAR 6293).

       As mentioned in HSTAR 6294, the re-acquisition at 003/073953Z
succeeded, but a large roll error was indicated.  A realtime map confirmed
the error, and an ARU/PRT was uplinked at 003/0853Z.

       The ground master image was updated at 004/0851Z.

3.0 SIGNIFICANT FORTHCOMING EVENTS:

       Continuation of normal science observations and calibrations.
