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.
