Daily Status Report as of 335/0000Z

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

   1.2 Completed Five 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.

   1.3 Completed NIC/2 7230 (Dust Embedded Black Holes/AGN in Nearby Galaxies)

       The Near Infrared Camera (Camera Two) was used to make observations
of the AGN located in the nearby (i.e., 6.4 Mpc) spiral NGC-4418 galaxy.
The spin axis is at 119 degrees to that of the host spiral, but nearly
parallel to jets seen in H-Alpha and the radio continuum.  A dark
calibration image was also taken.  The observations were executed as
scheduled, and no anomalies were noted.

   1.4 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 quasar PG1354+213
which has indicated a relation between the luminosity of the nucleus and
the luminous mass of its host galaxy.  The observations completed as
planned, with no reported problems.

   1.5 Completed Six 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.

   1.6 Completed Two Sets of WF/PC-2 7282 (A Continuing Snapshot Survey for
Compact Stellar Groups and Clusters around Wolf-Rayet Stars)

       The WF/PC-2 was used to make observations of the Wolf-Rayet star
WR26 as part of a continuing snapshot survey of compact stellar groups and
clusters.  The newly imaged clusters allow us to accurately determine the
distances, luminosities, and ages of the WR members.  The observations were
executed as scheduled, and no anomalies were noted.

   1.7 Completed Four Sets of 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 bar of the Large Magellanic Cloud.  These data
will enable us to quantitativly study the intermediate to low-mass stellar
populations and the star-formation history of the LMC.  During the second
iteration of this proposal, the acquisition failure detailed in 2.1
occurred, and the take data flag remained down.  Then, in the following
iteration, as mentioned in 2.1O, the acquisition defaulted to fine lock on
one FGS only, possibly affecting that iteration.  Otherwise, the
observations were executed as scheduled, and no further anomalies were
noted.

   1.8 Completed NIC/2/3 7424 (NICMOS Imaging of QSO Absorption-- Selected
Galaxies at z > 1)

       The Near Infrared Camera (Cameras Two and Three) was used to make
observations of QSO/galaxy Q0347-383.  The images will also be used to
connect the absorption line properties to the galaxy morphological
properties, inclination angles, and orientations in order to continue to
explore the connection between the absorbing gas and the galaxies.  The
observations were completed as scheduled, and no anomalies were reported.

   1.9 Completed Four Sets of 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).  During the second
iteration of this proposal, the acquisition failure detailed in 2.1
occurred, and the take data flag remained down.  Then, in the following
iteration, as mentioned in 2.1O, the acquisition defaulted to fine lock on
one FGS only, possibly affecting that iteration.  Otherwise, the
observations were executed as scheduled, and no further anomalies were
noted.

   1.10 Completed Eleven Sets of STIS/CCD 7783 (STIS Parallel Science)

   1.11 Completed Five 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.

   1.12 Completed Eighteen 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.

   1.13 Completed Three Sets of FOC/96 6667 (The Far-UV Evolution of
Elliptical Galaxies)

       The Faint Object Camera (f/96) was used to make far-ultraviolet
observations of a large elliptical galaxy A370-9   (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.
The observations were executes as planned, and no problems were reported.

   1.14 Completed Seven Sets of NIC/2/3 7811 (NICMOS Modified One Orbit
Parallel)

       The near Infrared Camera (Cameras Two and Three) was used to obtain
"JH" imaging, and G096 and G141 spectroscopy of sky regions when another

positions are obtained for each filter.  The observations were completed as
scheduled, and no anomalies were reported.

   1.17 Completed STIS/CCD/WF/PC-2/NIC/2 7388 (Black Holes and the Centers
of Galaxies)

       The Space Telescope Imaging Spectrograph (CCD), the WF/PC-2, and the
Near Infrared Camera (Camera Two) were used to continue our survey of
centers of the nearby galaxy NGC-4473.  The major goal is to survey an
unbiased set of galaxies with a potentially wide range of black hole
masses.  The sample has been carefully chosen to optimize leverage on the
character of a proposed correlation of black hole mass with galaxy mass.
The observations were completed as scheduled with no anomalies.

   1.18 Completed Four Sets of STIS/CCD 7601 (CCD Dark and Bias Monitor)

       The Space Telescope Imaging Spectrograph (CCD) was used to conduct
bias and dark monitoring.  Also, observations were made to track the growth
of hot pixels on the CCD in general and within the various target
acquisition apertures specifically.  During the second iteration of this
proposal, the acquisition failure detailed in 2.1 occurred, and the take
data flag remained down.  Then, in the following iteration, as mentioned in
2.1O, the acquisition defaulted to fine lock on one FGS only, possibly
affecting that iteration.  Otherwise, the observations were completed as
planned, and no further anomalies were reported.

   1.19 Completed Two Sets of 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 Nova-Cru-1 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.

   1.20 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 Procyon.  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.

   1.21 Completed NIC/2 7498 (NICMOS Imaging Survey of Distant Radio
Galaxies. Ellipticals at Z > 2 ?)

       The Near Infrared Camera (Camera Two) was used to make high
resolution and high signal-to-noise ratio imaging survey observations of
the radio galaxy MRC1138-26.  The existence and photometric properties of
massive elliptical galaxies at high redshift provide a powerful probe of
galaxy evolution.  The observations were executed as scheduled, and no
anomalies were noted.

   1.22 Completed 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 it's 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.

   1.23 Completed Two Sets of NIC/1/2/3 7596 (NICMOS MULTIACCUM Dark
Characterization)

       The Near-Infrared Camera Multi-Object Spectrograph (Cameras One, Two
and Three) were used to make a NICMOS MULTIACCUM dark characterization.
The purpose of this proposal is to monitor the darks using three different
MULTIACCUM sequences.  The observations were executed as scheduled, and no
anomalies were noted.

   1.24 Completed Three Sets of 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.

   1.25 Completed WF/PC-2/STIS/CCD/NIC/1/2 7307 (The Formation and
Evolution of Rich Star Clusters in the LMC)

       The WF/PC-2, the Space Telescope Imaging Spectrograph (CCD), and the
Near Infrared Camera (Cameras One and Two) were used to make observations
of the rich star clusters which are located within the Large Magellanic
Cloud in order to study their formation and evolution.  These observations
will help us understand the origin and evolution of rich star clusters in
our own Galaxy.  The observations were complete as scheduled, and no
anomalies were reported.

   1.26 Completed WF/PC-2 6521 (A Search For Outgassing From Kuiper Belt
Objects)

       The WF/PC-2 was used to make observations of the Kuiper Belt object
199QB1 in order to detect forms of outgassing.  In the past three years
almost 30 small bodies lying on the inner edge of the proposed Kuiper-Belt
have been discovered using ground-based facilities.  These objects are now
being studied with the HST.  The observations were executed as scheduled,
and no anomalies were noted.

   1.27 Completed NIC/1/2 7251 (High-Resolution H-2 Images of Selected
Nuclear Starbursts)

       The Near Infrared Camera (Cameras One and Two) was used to make high
resolution observations of the H-2 region in the galaxy NGC-3256 in order
to study the molecular environments for star-forming activity in the
centers of mergers and interacting galaxies.  The observations were
completed as planned, and no problems were reported.

   1.28 Completed WF/PC-2 6776 (A Comparative HST Imaging Study of Radio
Galaxies and Hosts)

       A clear understanding of the nature of the host galaxies of
radio-quiet quasars , radio-loud quasars, and radio galaxies is of central
importance in any attempt to unify and relate the three main classes of
powerful active galaxies.  Existing HST studies of quasar hosts, whilst
producing many interesting new results, have yielded surprisingly little
hard information on the properties of the hosts themselves.  This imaging
study using the WF/PC-2 will remedy this situation by undertaking redder,
line-free observations of AGN PKS1004+13.  The proposal completed with no
reported problems.

   1.29 Completed NIC/2 7219 (Ultraluminous Infrared Galaxies)

       The Near Infrared Camera (Camera Two) was used to make observations
of the ultraluminous infrared galaxy IRAS10565.  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.

   1.30 Completed STIS/CCD/MA1/MA2 7269 (The 1997/98 Eclipse of VV Cephei)

       The Space Telescope Imaging Spectrograph (CCD, MA1 and MA2) was used
to make ultraviolet spectrographic observations of the long-period
eclipsing binary star HD208816 (a.k.a., VV-Cephei).  This eclipse will
provide an unprecedented opportunity to obtain spatially resolved
information about the density, ionization and velocity structure in the
outer atmosphere of the M supergiant primary.  A wave length calibration
observation was also taken.  The observations were completed as scheduled,
and no anomalies were noted.

   1.31 Completed Two Sets of 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.

   1.32 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.

   1.33 Completed WF/PC-2 6194 (WF/PC-2 Cycle 5: Polarization Proposal)

      The WF/PC-2 was used to make polarization observations of star
G191B2B at four different spacecraft roll angles.  This should permit a
detailed and independent calibration of each polarizer quads.  The
observations were executed as scheduled, and no anomalies were noted.

   1.34 Completed Two Sets of NIC/1/3 7419 (The Low Mass Stellar Luminosity
Function in Dwarf Spheroidal Galaxies)

       The Near Infrared Camera (Cameras One and Three) was used to study
the low mass stellar luminosity function in the dwarf galaxy NGC-104.  This
class of dSph satellite galaxies of the Milky Way provide the nearest, and
best studied, examples of dark-matter dominated systems.  They have stellar
velocity dispersions well in excess of those consistent with their mass
being predominantly in a stellar mass function at all like that of the
solar neighborhood, or of the galactic globular clusters.  The observations
were completed as planned, and no problems were reported.

   1.35 Completed 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 galaxy NGC-7479.  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.

   1.36 Completed STIS/CCD 7670 (MAMA Ramp-up Test)

       The Space Telescope Imaging Spectrograph (CCD) was used to conduct a
MAMA ramp-up test.  The purpose of this program is to measure the short
term stability of the count rates on both MAMA detector immediately after
high-voltage turn-on.  The observations were executed as scheduled, and no
anomalies were noted.

   1.37 Completed NIC/1/2 7514 (HST Observations of Orion -- Probing the
Origin of Abundance Anomalies in H II Regions)

       The Near Infrared Camera (Cameras One and Two) was used to make
observations of the H-II region (i.e., NGC-1976) which is within the Orion
Nebula (a.k.a., M-42) in order to probe the origin of the abundance
anomalies in the nebula.  The purpose of the observations is to obtain a
set of emission-line diagnostics of the Orion Nebula in its brightest and
best-resolved H II region.  The observations were completed as scheduled,
and no anomalies were reported.

   1.38 Completed NIC/1/2/3 7268 (Nuclear Brightness Profiles of Merger
Remnants; Do Mergers Form Ellipticals?)

       The Near Infrared Camera (Cameras One, Two and Three) was used to
make observations of the elliptical galaxy NGC-2418.  Many elliptical
galaxies might have formed from mergers of disk galaxies.  Numerical
simulations yield elliptical-like remnants and observed merger remnants
have R^1/4 surface brightness profiles.  However, while the global
properties of merger remnants and ellipticals are similar, it is unknown
whether this is true for their nuclear properties as well.  The
observations were executed as scheduled, and no anomalies were noted.

   1.39 Completed FGS 7677 (Monitor the Long Term Stability of FGS-3)

       The goal of these measurements is to monitor the internal positional
stability of FGS3 by measuring many stars in the M35 check field repeatedly
over a one year period.  The results of these measurements are the
stability characteristics of FGS3 which allow an estimate of differential
corrections to OFAD and plate scale.  The measurements were completed as
scheduled. with no reported anomalies.

   1.40 Completed STIS/CCD 7398 (White Dwarf Stars in Visual Binaries:
Testing Stellar Degeneracy)

       The Space Telescope Imaging Spectrograph (CCD) was used to make
observations of the white dwarf star the visual binary system Apha-Cmi.
White dwarfs, the final evolutionary endpoints for most stars, are
important to our understanding of stellar evolution and to our testing of
critical aspects of fundamental physics.  The observations were executed as
scheduled, and no anomalies were noted.

2.0 FLIGHT OPERATIONS SUMMARY:

   2.1 Guide Star Acquisitions:

                            Scheduled Acquisitions : 39
                                        Successful : 38

       The acquisition scheduled for 331/0459Z failed.  HSTAR 6253 was
written.  Proposals described in 1.7, 1.9, and 1.19 were affected.

       The acquisition scheduled for 331/0818Z defaulted to fine lock on
one FGS only.  HSTAR 6254 was written.  The proposals mentioned in 1.7,
1.9, and 1.19 may have been affected.

                          Scheduled Reacquisitions : 34
                                        Successful : 34

   2.2 FHST Updates:

                              Scheduled : 76
                             Successful : 76

   2.3 Operations Notes:

       The STIS bad pixel table was uplinked at 330/1722Z.

       At 334/080032Z, while one of the iterations of the STIS proposal
described in 1.24 was executing, a STIS NSSC-1 status buffer message
occurred, indicating that a calibration lamp input mechanism re-try had
occurred.  At 334/1228Z, the STIS errors were cleared using ROP NS-12.

       One two occasions, at 334/0043Z and at 335/0728Z, operations note
#382 was invoked.  SSA transmitters were turned off to avoid TRMM mutual
RFI.

       During a ZOE, at 335/053513Z, a STIS MCE-1 reset occurred while the
high voltage for MAMA-1 was on.  As a result, STIS 7308 (which will appear
in tomorrow's report) had five of its observations lost.  HSTAR 6258 was
written.  The next high voltage on is not scheduled until 336/0256635Z, so
the recovery for MAMA-1 will not occur until later this morning during
regular business hours.

3.0 SIGNIFICANT FORTHCOMING EVENTS:

       Continuation of normal science observations and calibrations.
