HUBBLE SPACE TELESCOPE

DAILY REPORT #1596

PERIOD COVERED: 0000Z (UTC) 03/21/96 - 0000Z (UTC) 03/22/96

Daily Status Report as of 082/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

1.1 Completed WF/PC-2 5939 (Evolution in the Isotropic Properties of =
BL Lac Objects)

The WF/PC-2 was used to make observations of the BL Lac object =
PKS1538+14 in order to study its evolution and isotropic properties. The =
observations were completed as planned, and no problems were reported.

1.2 Completed WF/PC-2 6187 (WF/PC-2 Cycle 5 Calibration: Earth Flat)

The WF/PC-2 was used to make Earth streak flat calibration images. =
These streak flats will be used to produce flat fields, to map the OTA =
illumination pattern and, in combination with other data, to produce new =
superflats. The observations were completed as planned, and no problems =
were reported.

1.3 Completed GHRS/2 5862 (Boron in Very Metal Poor Stars: Production =
of Light Elements)

The High Resolution Spectrograph (Side Two) was used to make =
spectrographic observations of the very metal poor halo star HD84937 =
looking for the presence of the element Boron. The data will help =
differentiate the proposed production mechanism for boron and beryllium. =
A wavelength calibration image was also taken. The observations were =
completed as planned, and no anomalies were reported.

1.4 Completed GHRS/2 5892 (Physical Conditions in the Galactic Halos =
of the Milky Way and NGC-306)

The High Resolution Spectrograph (Side Two) was used to make =
observations of the radio galaxy/quasar 3C232 in order to study the metal =
absorption line system produced in the line of sight by the gas in the =
Milky Way and galaxy NGC-3076 halos. The observations were executed as =
scheduled, and no anomalies were noted.

1.5 Completed WF/PC-2 5992 (The Host Galaxies and Environments of BL =
Lacertae Objects)

The WF/PC-2 was used to make short and deep observations of the BL =
Lacertae class object OJ287. The short exposures will allow study of the =
inner regions of the host galaxy. The longer exposures will allow a =
search for faint galaxy companions and any interaction between the faint =
companion and the AGN. As reported in HSTAR 5540, the FGS acquisition =
for this proposal failed. No other anomalies were noted.

1.6 Completed FOS/BL 5890 (Far-UV Extinction for Deeply Embedded Stars =
in Interstellar Clouds.)

The Faint Object Spectrograph (Blue Side) was used to make =
ultraviolet observations of NGC-2024-05 to measure the UV extinction of a =
star which is deeply imbedded in an interstellar cloud. The objective is =
to determine the properties of the grains as a function of the depth in =
the cloud. The observations were completed as planned, and no problems =
were reported.

1.7 Completed WF/PC-2 5971 (HST Medium Deep Survey)

The WF/PC-2 was used to make a long exposure medium deep sky =
survey observations at latitudes larger than 10 degrees taken in parallel =
with the prime science observations. 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 : 3

One acquisition, at 081/2022Z failed when the search radius was =
exceeded. The following reacquisition was successful. HSTAR 5540 was =
written.

Scheduled Reacquisitions : 12
Successful : 12

2.2 FHST Updates:

Scheduled : 6
Successful : 6

2.3 Operations Notes:

The re-conditioning activities for the ESTRs were completed early =
this morning.

3.0 SIGNIFICANT FORTHCOMING EVENTS:

Nothing at this time.
