HUBBLE SPACE TELESCOPE
DAILY REPORT #1085

PERIOD COVERED: 0700 EST
Daily Status Report as of 060/1200Z.

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

1.1 Completed FOS/RD/BL 4774 (SMOV FOS Internal Monitor)

The Faint Object Spectrograph was used on both the Red and Blue
Sides to make a set of internal wavelength calibration images as
part of the SMOV program. All standard gratings were used with
different apertures. Eight observations were received and displayed.
They were reported to look okay.

1.2 Completed Two Sets of WF/PC-2 4709 (WF/PC-2 Internal Monitor)

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

1.3 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
stars 1150+497IN, 2541-REF, and INCA-221-73 and a nearby
extragalactic object which is known to have a small angular
separation. The observations were monitored, and no anomalies were
seen in the telemetry.

1.4 Completed WF/PC-2 5370 (HST Medium-Deep Survey: Cycle 4 Medium, 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 main purpose of these observations is to study the
evolution and structure of galaxies. The observations were executed
as scheduled, and no anomalies were noted.

1.5 Completed FOS/BL 4773 (SMOV COSTAR/FOS Sensitivity MST)

The Faint Object spectrograph (Blue Side) was used to make
observations of standard star WD0501+527 to measure the absolute
sensitivity of the FOS detectors. The observations were completed in
fine lock as expected. The observations were executed without
apparent anomaly. There was one FGS recentering event which was
reported to have occurred during the observations.

1.6 Completed Three Sets of WF/PC-2 5240 (SMOV-WF/PC-2 Flat Fields
Calibration)

The WF/PC-2 was used to make a visual internal flat image.
The image was received and displayed. It was reported to be okay.

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 observations were
monitored in the OSS, and the data quality was assessed. No
anomalies were noted.

1.8 Completed FOS/RD 4776 (FOS SMOV Spectral Flat Fields)

The Faint Object Spectrograph (Red Side) was used to make
observations of white dwarf star G191B2B (aka WD0501+527) which is
known to have a hot hydrogen atmosphere and a relatively featureless
ultraviolet spectrum. These observations will help provide a flat
field calibration of the system. The observations were executed as
scheduled, and no anomalies were noted.

2.0 FLIGHT OPERATIONS SUMMARY:

2.1 Guide Star Acquisitions:

Scheduled Acquisitions : 4
Successful : 4
Scheduled Reacquisitions : 9
Successful : 9

2.2 FHST Updates:

Scheduled :6
Successful :6


2.4 Operations Notes:

During the past 24 hours, there were no reported HST subsystem
anomalous behavior.

All SMOV activities proceeded nominally. Early in the day, the
secondary mirror was successfully repositioned in conjunction with
the WF/PC-2 fine alignment proposal.

3.0 ACTIVITIES SCHEDULED FOR NEXT REPORTING PERIOD:

3.1 Complete Three Sets of WF/PC-2 5240 (SMOV-WF/PC-2 Flat field
Calibration)

3.2 Complete Two Sets of WF/PC-2 5092 (GTO Low Latitude Parallel
Program: Cycle 4)

3.3 Complete Two Sets of FOS/RD 4776 (FOS SMOV Spectral Flat Fields)

3.4 Complete WF/PC-2 4709 (WF/PC-2 Internal monitor)

3.5 Complete FOS/RD 4773 (SMOV COSTAR/FOS Sensitivity MST)

4.0 ANOMALY STATUS:

4.1 Significant New Anomalies: None

4.2 Significant Unresolved Anomalies: None

5.0 SIGNIFICANT FORTHCOMING EVENTS:

Nothing at this time.
