HUBBLE SPACE TELESCOPE
DAILY REPORT #1178

PERIOD COVERED: 0700 EST
Daily Status Report as of 193/1200Z.

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

1.1 Completed WF/PC-2 5442 (Spectrophotometry and Imaging of Lensed,
Clover Leaf))

The WF/PC-2 was used to make observations of the gravitionally
lensed quasi-stellar system Q1413+117 (aka. the Clover Leaf). The
observations were executed as scheduled. Two observations were
received and displayed. They were reported to be nominal.

1.2 Completed WF/PC-2 5568 (WF/PC-2 Cycle 4 Calibration: Decon)

The WF/PC-2 was used to make internal flat, K-spot, and dark
calibration observations as part of a decontamination operation.
Eleven observations were received and displayed. They were reported
to look okay.

1.3 Completed Two Sets of FGS 3856 (A Critical Test of the Galactic
Escape Velocity at R(Sun))

FGS-3 were was to make parallax astrometric observations of star
G166-37, and reference star G166B-REF. The astrometry was monitored
while the telemetry was available. No problems were seen, except
during the second set of observations, where a stop flag was set on
FGS-3 while it was observing the target G166B-REF.

1.4 Completed WF/PC-2 5662 (Cycle 4 DD HST Observations of Comet
Shoemaker-Levy(9993) for July 1)

The WF/PC-2 was used to make images of the comet Shoemaker-Levy
(SL-7) to help refine the size estimates of the various components
of the comet train. The observations were executed as scheduled.
Four observations were received and displayed. They were reported to
be nominal.

1.5 Completed FOS/RD 5455 (The Level of Ionization and Chemical
Composition of QSO BAL Region Gas)

The Faint Object Spectrograph (Red Side) was used to make
ultraviolet observations of quasi-stellar object (QSO) Q1309-0536
which is known to have broad absorption lines (BALs). The onboard
target acquisition was successful. The first spectrum was nominal.

1.6 Completed WF/PC-2 5369 (HST Medium Deep Survey: Cycle 4 Medium, High
Galactic Latitude)

The WF/PC-2 made a series of observations of high latitude objects
as part of a medium deep sky survey. The observations were taken in
parallel with other prime science observations. The observations
were executed as scheduled.

1.7 Completed WF/PC-2 5560 (WF/PC-2 Cycle 4 Calibration: Internal
Monitor. 1)

The WF/PC-2 was used to make several internal bias, K-Spot, and flat
calibration observations to monitor the CCD camera electronics, the
optical alignment, and to check for contamination. The observations
were executed as scheduled. The observations remain on Science Tape
Recorder #1, and they will be analyzed later.

1.8 Completed WF/PC-2 5629 (WF/PC-2 Cycle 4 Photometric Calibration
Monitor 1C: 4-Chip STD in F170W)

The WF/PC-2 was used to make photometric calibration observations of
the ultraviolet standard star GRW+70D582. The observations were
executed as scheduled. The observations remain on Science Tape
Recorder #1, and they will be analyzed later.

1.9 Completed WF/PC-2 5370 (HST Medium Deep Survey: Cycle 4 Medium,
High Galactic Latitude: CR-SPILT))

The WF/PC-2 was used in parallel with the prime science observations
to make high galactic latitude observations as part of a medium-deep
sky survey. The observations were executed as scheduled.

1.10 Completed WF/PC-2 5427 (Calibration of Nearby Galaxy Type
IA Supernovae as Standard Candles)

The WF/PC-2 was used to make observations of nearby galaxy NGC-4536
as part of an effort to find Cepheids in this galaxy which has
produced a Type I supernova. The observations were executed as
scheduled.
