HUBBLE SPACE TELESCOPE

DAILY REPORT #1712

PERIOD COVERED: 0000Z (UTC) 09/05/96 - 0000Z (UTC) 09/06/96

Daily Status Report as of 250/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

1.1 Completed FGS 6883 (Orbital Parameters of Known Binary)

The FGSs were used to make astrometric observations of the known =
binary star system SAO103656 (aka ADS 11300) in order to obtain its =
orbital parameters. The target is a known double star with an orbital =
period of 54 years. The observations were executed as scheduled, and no =
anomalies were noted.

1.2 Completed Three Sets of WF/PC-2 6253 (Pure Parallel Archive =
Program)

The WF/PC-2 was used to execute a pure parallel program taking =
ultraviolet observations running concurrently with prime science =
observations. The intent is to search for extra-galactic sources with =
flux excesses at 3000 A0 and galactic sources with excesses at 1600 A0. =
The observations were completed as planned, and no problems were =
reported.

1.3 Completed FOS/BL 6817 (The Ultraviolet Spectrum of Callisto)

The Faint Object Spectrograpg (Blue Side) was used to make =
ultraviolet spectra observations of Jupiter's moon Callisto, looking for =
evidence of surface contaminants. The observations were completed as =
planned, and no probles were noted.

1.4 Completed FGS 6495 (The Mass of the Bright Giant HD173764)

The FGSs were used to make astrometric observations of bright, =
spectrographic binary system, giant star HD173764. The binary system has =
a 832 day period. The objective is to determine the individual masses of =
the G4 and B9 class pair. The observations were completed as scheduled, =
and no anomalies were noted.

1.5 Completed FOC/96 6531 (Correlated Study of the Outer Magnetosphere =
With FOC, GHRS, and Galileo Probe)

The Faint Object Camera (f/96) was used to make observations of =
Jupiter's aurora at both poles. The observations will be correlated with =
data obtained from the Galileo space probe which is in orbit around the =
planet Jupiter. The observations were completed as planned, and no =
problems were reported.

1.6 Completed WF/PC-2 6361 (High Resolution Imaging of X-Ray Selected =
AGNs)

The WF/PC-2 was used to make high resolution observations of the =
known low red shifted x-ray active galactic nucleus (AGN) MS1545.3+0. =
These data will allow a study of the optical properties of an unbiased =
sample of AGN host galaxies. The observations were completed as =
scheduled, and no problems were reported.

1.7 Completed FOS/BL 6206 (FOS Polarimetry Calibration)

The Faint Object Spectrograph (Blue Side) was used to make =
observations of standard star BD+64D106 to determine the most useful =
spectropolarimetric modes. The investigators will determine the =
locations of the polarization spectra, the transmission of the polarizer, =
the angles of the Wollaston prisms and waveplates in celestial =
coordinates, and the instrumental polarization. The observations were =
completed as planned, and no anomalies were reported.

1.8 Completed WF/PC-2 6802 (Cosmology With the Medium Deep Survey)

The WF/PC-2 was used to make some medium deep observations in =
parallel with the prime science observations. The observations were =
executed as scheduled, and no anomalies were noted.

1.9 Completed FGS 6873 (Parallaxes of Hyades Cluster Members, Cycle 6 =
- High)

The FGSs were used to make parallax astrometric observations of =
the star VA310 and several other reference stars within the Hyades star =
cluster. When the data from this cycle is combined with previuosly =
obtained data, the population 1 zero age main sequence will be better =
defined. The observations were completed as scheduled, and no anomalies =
were reported.

1.10 Completed FGS 6874 (Parallaxes of Hyades Cluster Members, Cycle 6 =
- High)

The FGSs were used to make parallax astrometric observations of =
the stars VA622 and VA627 and several other reference stars within the =
Hyades star cluster, to better define the Population 1 zero age main seque=
nce. The observations were completed as planned, and no problems were =
reported.

2.0 FLIGHT OPERATIONS SUMMARY:

2.1 Guide Star Acquisitions:

Scheduled Acquisitions : 7
Successful : 7

Scheduled Reacquisitions : 8
Successful : 8

2.2 FHST Updates:

Scheduled : 14
Successful : 14

2.3 Operations Notes:

Upon completion of GSFC Internal Simulation #9 (EVA 1), HST =
operations personnel return to the STOC from the SAMS back-up facility.

The PRS real-time system failed to uplink a DF-224 load patch =
during a gyro bias update load procedure. Using manual means, the load =
was uplinked. Later the same PSTOL procedure was successfully used to =
uplink the load. HSTAR 5701 was written.

3.0 SIGNIFICANT FORTHCOMING EVENTS:

Nothing at this time.
