HUBBLE SPACE TELESCOPE

DAILY REPORT #3057

PERIOD COVERED: 0000Z (UTC) 02/14/02 - 0000Z (UTC) 02/15/02

Daily Status Report as of 046/0000Z

1.0 OBSERVATIONS SCHEDULED AND ACCOMPLISHED:

1.1 Completed Three Sets of 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.

1.2 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.

1.3 Completed Two Sets of STIS/CCD 8901 (Dark Monitor-Part 1)

The Space Telescope Imaging Spectrograph (CCD) was used to monitor
the darks. There was no anomalous activity.

1.4 Completed STIS/CCD 9128 (A Snapshot Survey of Absorption Lines from
High Velocity Clouds in the Milky Way)

The Space Telescope Imaging Spectrograph (CCD) was used to search
for Mg II and Mg I absorption from Galactic High Velocity Clouds {HVCs}
along the sightlines of 51 of the brightest QSOs, BL Lacs and Seyfert 2
galaxies in the sky. The observations completed with no reported problems.

1.5 Completed Two Sets of WF/PC-2 9111 (The UV Light Echo of Shock
Breakout During SN 1987A)

The WF/PC-2 was used to observe light echoes {transient reflection
nebulae} from SN1987A that were discovered in the optical in 1988 and have
been detected in the vacuum ultraviolet by IUE. The proposal completed
with no reported problems.

1.6 Completed STIS/MA2 9573 (NUV-MAMA Daily Dark Monitor)

The Space Telescope Imaging Spectrograph (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.

1.7 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.

1.8 Completed STIS/MA1 8643 (Ultraviolet Properties of the Metal Rich
M87 Globular Cluster System)

The Space Telescope Imaging Spectrograph (MA1) was used to We
propose to obtain far-ultraviolet photometry of the metal rich globular
cluster system of the elliptical galaxy M87. This system represents a key
link between the well-understood populations of the clusters and the hot
stars in elliptical galaxies, where our physical insight is presently
limited. The goal is to establish the relationship between cluster metal
abundance and the production of UV-bright populations of stars on the
"extreme horizontal branc"' at T{eff} > 16000K. No anomalies were reported.

1.9 Completed STIS/CCD/MA1/MA2 9036 (An Ultraviolet Spectroscopic
Survey of Star-Forming Galaxies in the Local Universe)

The Space Telescope Imaging Spectrograph (CCD, MA1 and MA2) was
used to perform a comprehensive STIS ultraviolet spectroscopic survey of
star-forming galaxies in the local universe. The sample covers a broad
range of morphologies, chemical composition, and luminosity. The
observations will provide spectral coverage between 1200 and 3100 Angstrom,
at a resolution of 100 to 200 kms and S/N of about 30. The data set will
allow the proposers to document and quantify the effects of massive stars
on the interstellar medium and to infer implications for the evolution of
the host galaxies. The proposal completed with no anomalous activity.

1.10 Completed STIS/CCD 8903 (Bias Monitor - Part 1)

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 to build up high-S/N superbiases and track the evolution of hot
columns. There were no problems.

1.11 Completed STIS/CCD/MA1/MA2 8926 (Filter Throughput Monitor)

The Space Telescope Imaging Spectrograph (CCD, MA1 and MA2) was
used to take slitless spectra through a number of filters to look for
throughput changes. This is done by comparing slitless spectra taken
through each filter to unfiltered slitless spectra of the same target. The
proposal completed with reported incident.

1.12 Completed 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.

2.3 Operations Notes:

The SSR-1 EDAC error counter was cleared three times per ROP SR-1A.

Using ROP IC-2, SSA transmitter #2 was powered on for the interval
045/1329Z to 045/1342Z.

The STIS MCE-1 reset at 045/210905Z while the low voltage was on
and while outside any SAA interval. The STIS flight software error counter
was cleared at 045/2116Z as directed by ROP NS-12. MAMA-1 will be
recovered at 046/2012Z via normally inserted SMS commanding.

A TTR was written for a required re-transmit at 046/03212Z during a
NSSC-1 load. SI C&DH errors were reset at 046/0325Z per ROP NS-05.

3.0 SIGNIFICANT FORTHCOMING EVENTS:

Continuation of normal science observations and calibrations.
