HUBBLE SPACE TELESCOPE

DAILY REPORT #1652

PERIOD COVERED: 0000Z (UTC) 06/10/96 - 0000Z (UTC) 06/11/96

Daily Status Report as of 163/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

1.1 Completed Four Sets of WF/PC-2 6188 (WF/PC-2 Cycle 5 Calibration: =
Dark)

The WF/PC-2 was used to make internal dark calibration images. =
The observations were completed as scheduled, and no problems were =
reported.

1.2 Completed WF/PC-2 5997 (The Cores of Elliptical Galaxies in the =
Coma Cluster)

The WF/PC-2 was used to make observations of the large elliptical =
galaxies IC3623 and NGC4673 which are located in the Coma Cluster. The =
purpose is to study the luminosity profiles in their central nuclear =
regions. The observations were completed as scheduled, and no anomalies =
were noted.

1.3 Completed FOS/BL/GHRS/1 5947 (The Relationship Between Galaxies =
and Lyman-Alpha Absorbers at Low Redshift)

The Faint Object Spectrograph (Blue Side) and the High Resolution =
Spectrograph (Side One) were used to make observations of Quasar =
PG-1211-14 to study the relation ship between its galaxy and Lyman-Alpha =
Absorbers at Low Redshift. The relationship between the galaxy and low =
column density, metal poor quasar absorbers is poorly understood. The =
observations were executed as scheduled, and no anomalies were noted.

1.4 Completed 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.

1.5 Completed FOS/RD 6025 (Consequences of the Shoemaker-Levy Impact =
With Jupiter)

The Faint Object Spectrograph (Red Side) was used to make =
spectrographic observations of the planet Jupiter in order to study the =
consequences from the impact of the comet Shoemaker-Levy. This is to =
study the atmosphere following the impact to measure the chemical =
abundances as a function of time. The observations were completed as =
scheduled, and no problems were reported.

1.6 Completed WF/PC-2 6964 (Photometry of Candidate Dwarf Spheroidal =
Galaxies in the M81 Group)

The WF/PC-2 was used to make photometric and two color images of =
the candidate dwarf, spheroidal galaxy (dSph) GAL-100441 which is located =
in the M-81 galaxy cluster group. From these data, a color-magnitude =
diagram will be constructed, which will allow the determination of =
various physical properties for the candidate dSphs. The observations =
were completed as scheduled, and no problems were reported.

2.0 FLIGHT OPERATIONS SUMMARY:

2.1 Guide Star Acquisitions:

Scheduled Acquisitions : 3
Successful : 3

Scheduled Reacquisitions : 13
Successful : 13

2.2 FHST Updates:

Scheduled : 4
Successful : 4

2.3 Operations Notes:

HST operations began experiencing problems with the load and file =
transfer function of the PRS ground system at 162/0731Z and, as a result, =
required uplinks to the HST cannot be performed. PRS programmers were =
called in but as of 163/1200Z the problems had not been solved. =
Currently both ephemeris loads and gyro bias loads need to be uplinked =
soon in order to forestall operational problems.

3.0 SIGNIFICANT FORTHCOMING EVENTS:

Nothing at this time.
