HUBBLE SPACE TELESCOPE

DAILY REPORT #3068

PERIOD COVERED: 0000Z (UTC) 03/01/02 - 0000Z (UTC) 03/02/02

Daily Status Report as of 061/0000Z

1.0 OBSERVATIONS SCHEDULED AND ACCOMPLISHED:

1.1 Completed Three Sets of WF/PC-2 8937 (Cycle 9 Supplemental Darks pt2/3)

The WF/PC-2 was used obtain three dark frames every day to provide
data for monitoring and characterizing the evolution of hot pixels. No
problems were encountered.

1.2 Completed Two Sets of STIS/CCD 8902 (Dark Monitor-Part 2)

The Space Telescope Imaging Spectrograph (CCD) was used to monitor
the darks. No problems were reported.

1.3 Completed STIS/CCD 9088 (Next Generation Spectral Library of Stars)

The Space Telescope Imaging Spectrograph (CCD) was used to produce
a "Next Generation'' Spectral Library of 600 stars for use in modeling the
integrated light of galaxies and clusters by using the low dispersion UV
and optical gratings of STIS. The library will be roughly equally divided
among four metallicities, very low {Fe/H < -1.5}, low {-1.5 < Fe/H < -0.5},
near-solar {-0.5 < Fe/H < 0.1}, and super-solar {Fe/H > 0.1}, well-sampling
the entire HR-diagram in each bin. Such a library will surpass all extant
compilations and have lasting archival value, well into the Next Generation
Space Telescope era. No problems occurred.

1.4 Completed Two Sets of WF/PC-2 9318 (POMS Test Proposal: WFII
Parallel Archive Proposal Continuation)

The WF/PC-2 was used to perform the generic target version of the
WFPC2 Archival Pure Parallel program. The program was used to take
parallel images of random areas of the sky, following the recommendations
of the Parallels Working Group. There were no reported problems.

1.5 Completed Two Sets of STIS/CCD 9317 (Pure Parallel Imaging Program:
Cycle 10)

The Space Telescope Imaging Spectrograph (CCD) was used to perform
the default archival pure parallel program for STIS during cycle 10. There
were no reported problems.

1.6 Completed STIS/CCD 8904 (Bias Monitor-Part 2)

The Space Telescope Imaging Spectrograph (CCD) was used to monitor
the bias in the 1x1, 1x2, 2x1, and 2x2 bin settings at gain=1, and 1x1 at
gain = 4 in order to build up high-S/N superbiases and track the evolution
of hot columns. The proposal completed with no anomalous activity.

1.7 Completed Seven Sets of WF/PC-2 8942 (Cycle 10 Intflat Sweeps and
Linearity Test)

The WF/PC-2 was used to monitor the pixel-to-pixel flatfield
response and provide a linearity check. These intflat sequences are done
once during the year and the images will provide a backup database in the
event of complete failure of the visflat lamp as well as allow monitoring
of the gain ratios. There were no reported problems.

1.8 Completed STIS/CCD/MA1 9179 (Calibrating Convection Efficiency With
Quasi-Molecular Features In Magnetic White Dwarfs)

The Space Telescope Imaging Spectrograph (CCD and MA1) was used to
observe recently-discovered quasi-molecular absorption features of Lyman
Alpha in UV spectra of magnetic white dwarfs taken with IUE. Hitherto,
such features have only been known in non-magnetic objects where they
offered a very accurate determination of the atmospheric parameters. There
were no reported problems.

1.9 Completed Six Sets of WF/PC-2 8940 (Cycle 10 Earth Flats)

The WF/PC-2 was used to monitor flatfield stability by obtaining
sequences of Earth streak flats to construct high quality flat fields for
the WF/PC-2 filter set. 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 proposal
completed without incident.

1.10 Completed STISMA1/MA2 9573 (NUV-MAMA Daily Dark Monitor)

The Space Telescope Imaging Spectrograph (MA1 and MA2) was used to
perform daily monitoring of the NUV MAMA detector dark noise in order to
monitor the effects of thermal changes on the NUV dark rate. No problems
occurred.

1.11 Completed STIS/CCD/MA2 9161 (The Ultraviolet Properties of
Obscured QSOs)

The Space Telescope Imaging Spectrograph (CCD and MA2) was used to
observe a subset of The Two Micron All-Sky Survey {2MASS}-discovered QSOs
to: 1} determine if UV absorption- line features are present as seen in
several other highly polarized AGN populations; 2} test relationships
between X-ray and UV/optical attenuation, AGN spectral type, optical
polarization, and detected UV absorption-line features; and 3} characterize
the spectral energy distributions and UV properties of obscured
QSOs. There were no problems.

1.12 Completed STIS/CCD/MA1/MA2 8919 (MAMA Sensitivity and Focus
Monitor C10)

The Space Telescope Imaging Spectrograph (CCD, MA1 and MA2) was
used to monitor the sensitivity of each MAMA grating mode to detect any
change due to contamination or other causes, and also to monitor the STIS
focus in a spectroscopic and an imaging mode. All observations were
successful.

1.13 Completed STIS/CCD 8907 (Spectroscopic Flats C10)

The Space Telescope Imaging Spectrograph (CCD) was used to obtain
CCD flats in the spectrographic mode. There were no reported problems.

1.14 Completed WF/PC-2 9145 (A Snapshot Survey of the Optically
Selected Type-2 Quasars)

The WF/PC-2 was used to observe an identified population of
emission-line objects in DPOSS, which can be plausibly interpreted as the
long-sought type-2 quasars. They have high-ionization Seyfert-2 like
spectra, but with narrow-line luminosities comparable to those of the
luminous type-1 quasars in the same redshift range. This population may be
a major contributor to the cosmic hard x-ray background. It is proposed to
obtain multi-color images of a representative sample of these objects, in
order to examine their morphology. We may be able to detect point-like
nuclei which are not detectable in ground-based images, the dust lanes
hiding them from our view, possible evidence for tidal interactions and the
overall morphology of their hosts, etc. The proposal completed with no
reported problems.

1.15 Completed HST 4779 (Vehicle Attitude And SI Configuration For
Servicing Mission)

In support of the Servicing Mission 3B, the vehicle must be at a
+V3 sun pointing attitude. The science instruments must be in the launch
configuration. This proposal defines the end of the last STScI SMS.
