BL-Lac Objects)

       The WF/PC-2 was used to make snapshot survey observations of BL-Lac
object MS0122.1+0in order to study its environment and its host galaxy. The
goal is to investigate systematic trends in host galaxy type, unusual
morphological features, nearby companion galaxies, etc. The observations
were executed as scheduled, and no anomalies were noted.

   1.20 Completed Seven Sets of STIS/MA1 7669 (Incidence Angle Correction
for Non-Concentric Slits-MAMA)

          The Space Telescope Imaging Spectrograph (MA1) was used to make
calibration images needed to find the incidence angle correction for
non-concentric slits-MAMA.  This test will provide incidence angle
corrections for MAMA observations using non-concentric slits. This tests
fills in missing calibrations from ground testing.  The observations were
completed as planned and no anomalies were reported.

   1.21 Completed Three Sets of STIS/MA1 6854 (Saturn's Aurora and Airglow)

       The Space Telescope Imaging Spectrograph (MA1) was used to make
ultraviolet images of the planet Saturn's aurora and air glow regions.
Saturn's auroral energy is radiated from the morning sector in both polar
regions, peaking near dawn, and that intensities are variable on 10-minute
time scales. This suggests that magnetosphere-solar wind interactions play
a dominant role in powering the auroral emissions.  The observations were
completed as planned, a no anomalies were reported.

   1.22 Completed WF/PC-2 6871 (AGN in Low Luminosity Galaxies)

       The WF/PC-2 was used to make images of the low luminosity galaxy

non-scripted parallel archive proposal (one-half orbit).  The observations
were executed as scheduled, and no anomalies were noted.

   1.24 Completed Two 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

as planned, and no anomalies were reported.

   1.25 Completed NIC/2 7212 (Polarization in Galactic Nuclei)

       the Near Infrared Camera (Camera #2) was used to make polarizational
observations of the galaxy NGC-1068.  Comparison of these images with
corresponding visible data taken with HST will provide unique constraints
on the structure and emission mechanisms in the galaxy.  Comparison with
the optical polarimetry will help to understand the relative importance of
mechanisms which produce the polarization.  A dark calibration image was
also taken.  The observations were completed as scheduled, and no anomalies
were reported.

   1.26 Completed Two Sets of NIC/1/2 7442 (Circumbinary Disks: Tracing the
Mass and Energy Transfer in Young Binary Systems)

       The Near Infrared Camera (Cameras 1 and 2) was used to make
observations of the circumbinary disks around stars GG-Tau and NTTS-042417
in order to trace the mass and energy transfer in these binary systems.
The primary purpose of these observations is to ascertain whether or not
the gap between the circumbinary and circumstellar disk is devoid of
material or in fact contains filaments which can transfer mass to the inner
disks that would otherwise be rapidly depleted of material.  The
observations were completed as planned, and no problems were reported.

of the binary system HD47839 and HD38666 (a.k.a., 15-Monocerotis).  FGS
measurements of separation, position angle, and magnitude difference are
needed to bridge the gap between current speckle observations and the next
generation of optical interferometers.
There was a multiple guide star acquisition failure at 286/0112Z Fine
Guidance Sensor (FGS) #1 failed walkdown causing FGS #2 it drop lock.  FGS

       The FGSs were used in the TRANS mode to make astrometric
observations of the per-main sequence, binary star system ROX-42B in order
to help compute its orbital parameters.  The observations will be used to
make orbital maps of T-Tauri class stars. From these orbital parameters
they will be able to derive the first reliable mass measurements for low
mass pre-main sequence stars. The observations were completed as scheduled,
and no anomalies were reported.

   1.31 Completed STIS/CCD 7636 (STIS Spectroscopic CCD Flatfielding)

   1.32 Completed NIC/2 7176 (Search for a Dust Ring Around Mars)

       The Near Infrared Camera (Camera #2) was used to make observations
of the planet Mars to search for a possible dust ring.  Speculation has
long held that a ring of dust particles, sputtered off the dusty surfaces
of Phobos and Deimos, must lie in the equatorial plane of Mars.  The Earth
will pass through the Mars equatorial plane on 2 November 1997.  A dark
calibration image was also taken.  The observations were completed as
planned, and no anomalies were reported.

Pedestal D.  The purpose of this proposal is to obtain on-orbit darks for
the MULTIACCUM predefined sequences requested by GOs, after day 233 of
1997.  The observations were executed as scheduled, and no anomalies were
noted.

   1.40 Completed Three Sets of WF/PC-2 7619 (WF/PC-2 Cycle 7 Decontamination)

       The WF/PC-2 was used to conduct a Cycle 7 Decontamination Procedure.
Ultraviolet-blocking contaminants are removed, and hot pixels cured, by
warming the CCDs to +20C for 6 hours. A variety of internal images are
taken before and after the decontamination in order to verify its success
and to monitor the instrument health.  The procedures were conducted as
scheduled, and no problems were reported.

   1.41 Completed Two Sets of STIS/CCD/MA1 7392 (Raman scattering and X-ray
ionization in LMC X-4)

       The Space Telescope Imaging Spectrograph (MA1) was used to make
observations of LMCX-4 in order to study its Raman scattering and X-ray
ionization.  This is a X-ray pulsar with O star companion.  The aim is to

spectra and to study their orbital modulation.  The observations were
completed as planned, and no anomalies were reported.

   1.42 Completed Two Sets of STIS/MA2 7604 (Cycle 7 MAMA Dark Measurements)

       The Space Telescope Imaging Spectrograph (MA2) was used to make MAMA
dark measurements.  These darks will be used in later image reductions and
also trended over the instrument's life time as an indicator of the
detector's degradation or damage.  The Space Telescope Imaging Spectrograph
(STIS) MCE reset outside the South Atlantic Anomaly (SAA) with MAMA 1HV on
at 286/1002Z. A Status Buffer Error message was received. HSTAR 6193 was
wriiten.  The On-Call MOSES SI SE was notified.  See Item 1.42. No other
problems were reported.

   1.43 Completed NIC/1/3 7419 (The Low Mass Stellar Luminosity Function in
Dwarf Spheroidal Galaxies)

       The Near Infrared Camera (Cameras 1 and 3) was used to study of the
low mass stellar luminocity 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.

matter distribution of NGC-5383 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.

   1.46 Completed STIS/CCD 7656 (Spectroscopic and Imaging Sensitivity)
