HUBBLE SPACE TELESCOPE
DAILY REPORT #1083

PERIOD COVERED: 0700 EST
Daily Status Report as of 056/1200Z.

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

1.1 Completed FOS/RD 5614 (SMOV FOS/FGS Fine Alignment (1.0 Reference))

The Faint Object Spectrograph was used to make spectral observations
of the cluster NGC-188-225 to help determine the location of the 1.0
arcsecond aperture for both the Red and Blue Sides. A total of 12
observations were received and displayed. There was a recentering
event and some discrepancies were reported during the observations.
An acquisition image was severely distorted by the motion. Analysis
of the data is pending.

1.2 Completed Two Sets of WF/PC-2 5212 (Globular Cluster Formation in
Cooling Flow or Interacting Galaxies)

The WF/PC-2 was used to make observations of the globular cluster
ABEL-1795 to obtain some insight into the clusters formation
mechanism. The baseline guide star acquisition got fine lock, and
nine observations were received and displayed. Numerous recentering
events were reported to have occurred during the observations.

1.3 Completed Two Sets of WF/PC-2 5240 (SMOV-WFPC-2 Flat Fields
Calibration)

The WF/PC-2 was used to make a set of visual internal flat images.
Five images were received and displayed. Two were reported to be
underexposed, and the others were okay.

1.4 Completed WF/PC-2 5436 (Age and Population of Super Metal Rich
Globular Clusters)

The WF/PC-2 was used to make observations of the super metal rich
globular cluster NGC-6553 located in the central bulge of our
galaxy. The hope is to determine the age of this cluster. The
observations were monitored in the OSS, and the data quality was
assessed. No anomalies were noted.

1.5 Completed WF/PC-2 5204 (The Disks Around Young Stellar Objects )

The WF/PC-2 Camera was used to make observations of the variable
proto star HL-TAURI located in the Taurus molecular cloud to examine
the disk known to be around this stellar object. It is hoped that
this will determine the physical properties, albedo, particle size,
and its spatial distribution of particles in the disk. The
observations were executed as scheduled, and no anomalies were
noted.

1.6 Completed FGS 5587 (Parallaxes of Hyades Cluster Members: Cycle 4
High)

The Fine Guidance Sensor #3 was used to used to make astrometric
parallax observations of star PCEN-662 which is located in the
Hyades open cluster. This is to help compute the distance modulus of
the cluster. The astrometric observations were monitored in the OSS
when telemetry was available. No anomalies were noted.


1.7 Completed WF/PC-2 5092 (GTO Low Latitude Parallel Program: Cycle 4)

The WF/PC-2 was used to make observations taken in parallel with the
prime science observations. This is part of a survey to take a large
number of fields within 30 degrees of the galactic plan. The intent
is to determine the luminosity function of low mass stars and the
mass density in the solar neighborhood. The images were received as
scheduled, and no anomalies were noted.

1.8 Completed FGS 5583 (Long Term Stability Monitoring the FGS#3)

The Fine Guidance Sensor #3 was used to monitor the optical field
angle distortion by making astrometric observations of star OF55-REF
which is located in the open cluster M-35. The astrometric
observations were monitored, and no problems were seen in the
telemetry.

1.9 Completed WF/PC-2 5372 (HST Medium- Deep Survey: Cycle 4 Medium, Low
Galactic Latitude)

The WF/PC-2 was used to make low galactic latitude observations
taken in parallel with the prime science observations. Several
different filters were used. The observations were completed as
scheduled in fine lock, and no anomalies were noted.

1.10 Completed WF/PC-2 4709 (WF/PC-2 Internal Monitor)

The WF/PC camera was used to make a series of routine ultraviolet
flat calibration images to monitor the instrument's performance. The
observations were monitored in the OSS, and the data quality was
assessed. No anomalies were noted.

1.11 Completed FGS 5331 (Linking the HIPPARCOS to the Extragalactic
Reference Frame, FT0-11, Part 7)

Fine Guidance Sensor #3 was used to make astrometric observations of
star 0912+297-IN and a nearby extragalactic object which is known
to have a small angular separation. The observations were executed
as scheduled, and no anomalies were noted.
