Subj: HST REPORT #886

Note:
Both the AP-5 and AP-7 computers where down with problems on the
operational system disk. This made the ALLIN1 and MAIL functions
inoperative on Wednesday May 12, 1993, and Thursday May 13 causing a
delay in the distribution of the daily report via the electronic mail.


HUBBLE SPACE TELESCOPE
DAILY REPORT #886

PERIOD COVERED: 0800 EST
Daily Status Report as of 133/1200Z.

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

1.1 Completed Two Sets of FOS/BL 4697 (FOS Polarimetric Calibration)

The Faint Object Spectrograph was used to make a total of 17 calibration
observations on both the red and blue sides to obtain measurements of the
internal Pt-Ne lamps. All seventeen observations were received and
displayed. They were all reported to look okay. No unexpected problems
were noticed.

1.2 Completed GHRS/2 3945 (G160M Spectra of Eta Car S Condensation - Cycle 2)

The High resolution Spectrograph was used to make spectral observations
of a gaseous knot in the southern part of the nebula Eta Carnae. In the
first set of eleven observations, all were received and displayed. They
were reported to look okay. There were two carrousel resets events which
occurred, and generated status buffer error messages. The second
carrousel reset delayed the final wavelength calibration until one
minute after the scheduled start time of the final science
observations. This observation did not occur.

1.3 Completed Two Sets of FOC/96 3801 (Search for QSOs suitable for
Subsequent Observations of He II)

The Faint object Camera made ultraviolet images of five different quasars
(2139-4434, 2050-359, 2049-353, 2038-371, and 1601+3754) to observe the
level of their UV flux. Two recentering events occurred during two
separate observations, and no other anomalies were noted.

1.4 Completed WFC 4929 (WF/PC Cycle 2: Improved Dark Calibration)

The Wide Field Camera was used to make two dark calibrations images.
These were pre-flashed exposures which lasted 1200 seconds each. Both
images were received and displayed. No anomalies were noted.

1.5 Completed FOS/BL 4054 (Probing the Nuclear Regions of Seyfert Galaxy
NGC-5548)

The Wide Field Camera was used to make observations of Seyfert galaxy
NGC-5548 to look for time variations in its continuum, and emissions in
Helium II and Carbon IV. The observations were executed as scheduled, and
no problems were reported.

1.6 Completed WFC 4381 (HST Medium-Deep Survey Cycle 3)

The Wide Field Camera was used to make two high latitude medium-deep sky
survey observations taken in parallel with the prime science
observations. The OSS monitored the observations, and assessed the data
quality. No problems were reported.

2.0 FLIGHT OPERATIONS SUMMARY:

2.1 Guide Star Acquisitions:

Scheduled Acquisitions : 7
Successful : 4

The acquisition at 132/1443Z failed to attain fine
lock, but did obtain course track. Three subsequent
reacquisitions also failed fine lock, but obtained
course track.

Scheduled Reacquisitions : 4
Successful : 4
Losses of Lock : 0

2.2 FHST Updates:

Scheduled : 8
Successful : 8

2.3 Significant HSTARs: None

2.4 Operations Note:

The GSFC Internal Simulation (Type 1 + Replan) was conducted on
Wednesday, May 12, and Thursday May 13.

3.0 ACTIVITIES SCHEDULED FOR NEXT REPORTING PERIOD:

Observations)

3.2 Complete FOC/96 3504 (High Spatial Resolution Imaging and
Spectroscopy of AGNs: Cycle 2)

3.3 Complete WFC 4849 (GTO High Latitude Parallel Program: Cycle 3 High)

3.4 Complete FOC/96 3801 (Search for QSOs Suitable for Subsequent
Observation of He II)

3.5 Uplink Updated Ephemeris Tables, Per MOSES 2871

3.6 Complete GHRS/2 3664 (Probing the Gas of the Superbubble LMC2)

3.7 Complete FOS/BL 4054 (Probing the Nuclear Regions of Seyfert galaxy
NGC-5548)
