HUBBLE SPACE TELESCOPE
DAILY REPORT #841

PERIOD COVERED: 0800 EST
Daily Status Report as of 070/1200Z.

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

1.1 Completed FOS/BL 3538 ( UV spectra of Extended Emission Regions
Around QSOs)

The Faint Object Spectrograph (Blue Side) was used to make a set of
four observations of quasi-stellar object B2-1512+37 to obtain
spectra of the extended emission line region around the quasar. All
four observations were received and displayed. The first was the
binary target acquisition (eight groups), the second was the
confirmation image, and the last two were the scientific spectral
observations. The target was well centered in the 4.3 arcsecond
aperture. The spectral observations were reported to be weak and
noisy, but showed some signs of emission lines at the expected wave
lengths. The third observations was filed as being bad because of
high jitter during a night/day transition.

1.2 Completed Two Sets of S/C/FOS/BL 4099 (FOS focus, X-Pitch and
Y-Pitch)

The Faint Object Spectrograph was used to make two sets (of seven
observations each) as part of the focus and x/y pitch test. All
fourteen observations were received and displayed. They were
reported to be okay.

1.3 Completed FOC/96 4800 (Stellar content of Wolf-Rayet Galaxies)

The Faint Object Camera (f/96) was used to make one image of the
Wolf-Rayet Galaxy NGC-1741. The star burst galaxy is know to exhibit
broad He II emission lines from stellar sources. The observations
was executed without problems. The data was received and displayed.
There was roll-over in the central pixel for some of the brightest
objects, and the data looked good.

1.4 Completed WFC 4658 (Determination of Extragalactic Distance Scale)

An attempt was made to use the Wide Field Camera to make
observations of NGC-5457 (aka, M-101, a large spiral galaxy in Ursa
Major). The baseline guide star acquisition failed , because
the FHST update preceding it corrected only for roll, and not for
v2-v3 error. The subsequent reacquisition was executed with out
problems and it was received and was displayed. The first image was
empty, and the second was filled with stars and cosmic ray hits.

1.5 Completed GHRS/2 3626 (Ephemeral Determination fo wind Velocities and
Density Laws)

The High Resolution Spectrograph was used to make a series of eight
observations of the star Zeta Aurigae (aka, HD32068). The onboard
spiral search, and the peakup were successful. The wave length
calibrations, and the Echelle-B spectral observations were executed
without problems.

1.6 Completed PC 4140 (WF/PC Calibration: Rapid Internal Monitor Part 2)

The Planetary Camera was used to make internal flat observations to
check for new forms of contamination, and the reappearance of
quantum efficiency hysteresis (QEH). The observations were executed
as scheduled, and no problems were reported.

1.7 Completed Uplink Updated Ephemeris Tables, Per MOSES 2871

1.8 Completed GHRS/2 3496 (Ultraviolet Atlas of Sirius)

The High Resolution spectrograph was used to obtain ultraviolet
spectra of the star Sirius (aka, HD48915) in the WSCAN Mode to get
an accurate measurements of its flux distribution and line profiles.
The observations were executed as scheduled. There was an acquisition
failure at 070/0807Z and a reacquisition failure at 070/0943Z. The
observations were filed as bad.

1.9 Initiated FOC/96 3591 (Massive Stars in Starburst galaxies - FOC
Images)

The Faint Object Camera was used to initiate ultraviolet images of
the star bursting galaxy IZW18. The observations are currently under
way, and will be analyzed later.

2.0 FLIGHT OPERATIONS SUMMARY:

2.1 Guide Star Acquisitions:

Scheduled Acquisitions : 5 Successful : 3

(Failure at 069/2104Z, Attitude error, reason
is two V1-Axis updates after a major slew.)

(Failure 070/0807Z, the attitude looked
good, but no primary star found which exceeded
the threshold.)

Scheduled Reacquisitions : 7 Successful : 6

(Failure at 070/0943)

Losses of Lock : 0

2.2 FHST Updates:

Scheduled : 11 Successful : 11

2.3 Significant HSTARs: None

2.4 Operations Note:

The High Speed Photometer was successfully recovered from Safe Mode
yesterday (Wednesday 069/1836Z) using real-time commands. No
problems were reported.

3.0 ACTIVITIES SCHEDULED FOR NEXT REPORTING PERIOD:

3.1 Complete FOC/96 3591 (Massive Stars in Starburst Galaxies - FOC
Images)

3.2 Uplink Updated Ephemeris Tables, Per MOSES 2871

3.3 Complete FOC/96 4800 (Stellar Content of Wolf-Rayet Galaxies)

3.4 Complete HSP/POL Polorimetric Observations of the Crab Nebula Pulsar
in the UV)

3.5 Complete WFC 1306 (GTO Low Latitude Parallel Program)

4.0 ANOMALY STATUS:

4.1 Significant New Anomalies: None

4.2 Significant Unresolved Anomalies: None

5.0 SIGNIFICANT FORTHCOMING EVENTS: Nothing at this time.
