HUBBLE SPACE TELESCOPE
DAILY REPORT #1239

PERIOD COVERED: 0000Z
Daily Status Report as of 279/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

1.1 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, and no anomalies were noted.

1.2 Completed Three Sets of WF/PC-2 5508 (Tracking Features in Titan's
Lower Atmosphere and on Its Surface)

The WF/PC-2 obtained images of Saturn's moon Titan to look for cloud
features, and possibly surface features. The observations completed
with no reported errors.

1.3 Completed FGS 5749 (A Critical Test of the Galactic Escape Velocity
at R (Sun))

Fine Guidance Sensor #3 was used to perform POS mode astrometry of a
high proper motion star, G16-25, and reference stars, determining
parallax and improved proper motion. The parallax will make it
possible to determine the distance to the star more accurately,
which in turn will lead to an improved estimate of the tangential
component of its velocity. The proposal completed with no reported
errors.

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

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 completed as planned, and no
problems were reported.

1.5 Completed WF/PC-2 5479 (Subarcsecond Structure in Nearby AGNs)

The WF/PC-2 was used to make snapshot observations of the nearby
active galactic nuclei of IR2302-000 and NGC7213 to study the
interactions between the central engine, the stars, and the
interstellar matter in their AGNs. The observations were executed as
scheduled, and no anomalies were noted.

1.6 Completed FOS/RD 5664 (Quasar Absorption Line Survey: Cycle 4 High)

The Faint Object Spectrograph (Red Side) was used to make
spectrographic observations of quasi-stellar object PG2302+029 to
look for absorption lines due to gas in the intergalactic medium and
galactic halos. The telescope lost lock on the guide stars during
the onboard target acquisition at 278/1235Z, and the acquisition
failed. A subsequent acquisition in the series did succeed, however.

1.7 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 completed as scheduled, and no anomalies were noted.

1.8 Completed WF/PC-2 5677 (Blue Stragglers in M-80)

The WF/PC-2 was used to make observations of M-80 (aka, NGC-6093) in
Scoppius which has a varying central density to measure the density
and distribution of blue straggler stars. The proposal completed
with no reported errors.
