HUBBLE SPACE TELESCOPE
DAILY REPORT #838

PERIOD COVERED: 0800 EST
Daily Status Report as of 065/1200Z.

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

1.1 Completed PC 3603 (Snapshot of Protoplanetary Nebulae)

The Planetary Camera was used to make a single observations of the
protoplanetary nebulae system PK345-08D1. The observations was
executed in single star course track. It was received and displayed,
and was reported to look okay.

1.2 Completed Two Sets of FOS/RD 4212 (Internal Wave Length Calibration)

A total of seventeen wave length calibration images were taken with
the Faint Object Spectrograph. All seventeen observations were
executed on the Red Side, with various apertures, and gratings. All
the observations were received and displayed. They all were reported
to look okay.

1.3 Completed Four Sets of WFC 3172 (WF/PC SV Observational Monitoring
Proposal)

The wide Field Camera was used to make four internal flats, one
dark, and one KSPOT observations. The internal flats were reported
to be underexposed, and the other observations were reported to be
okay.

1.4 Completed FOS/RD 3858 (Inner Regions of Quasars)

The Faint Object Spectrograph was used to make two spectroscopic
observations of the luminous active galactic nucleus of quasar
PKS0859-14. Both observations were reported to be successful.

1.5 Completed FOS/RD 3744 (Spectrophotometry of Phobos and Deimos)

The Faint Object Spectrograph was used to make one spectral
observation of Mars' moon Deimos while it was at greatest
elongation. The Guaranteed Observer (GO) decided not to used the
ephemeris correction slew because it was very small. The spectral
observation was reported to look good.

1.6 Completed Two Sets of WFC/FOS/BL 3707 (HST Observations of Periodic
Comets)

The Wide Field Camera was used to make observations of the periodic
comet Schaumasse. Several corrective maneuvers were uplinked to the
spacecraft to make observations of the moving target. They were
successful. The observations were reproted to show good images of
the comet, and were rated as being satisfactory.

1.7 Completed GHRS/2 3626 (Empirical Determination of Wind Velocity)

The High Resolution spectrograph was used to make observations of
the eclipsing binary star Zeta Aurigae (aka, 32068) during its
eclipse phase. The objective was to use the B-dwarf star to probe
the atmosphere of the K class Supergiant primary. The target was
found of the first map. No problems were reported.

1.8 Completed GHRS/2 3210 (R136 G160M)


The High Resolution Spectrograph was used to make spectral
observations using grating G160M to look at the R136A complex which
is located in the Large Magellanic Cloud. The observations were
executed as scheduled, and no problems were reported.

1.9 Completed WFC/PC 4109 (WF/PC Calibration: Rapid Internal Monitor)

Both the Wide Field Camera and the Planetary Camera were used with
filter F555W to make internal flat observations to check for new
forms of contamination (i.e., daisies and measles) and to look for
the return of Quantum Efficiency Hysteresis. The observations were
executed as scheduled, and no problems were reported.

1.10 Completed PC/WFC 2607 (Black Holes, Stellar Dynamics and
Populations)

The Planetary Camera and the wide Field Camera were used to make a
total of seven observations of the nuclear regions of the
elliptical galaxy NGC-4374. The observations were made in signal
star course track. They all were received and displayed. they were
reported to look okay.

1.11 Completed PC 4347 (WF/PC Calibration: Flood Retention Test)

The Planetary Camera was used to make three Earth flat calibration
observations using filter F439W. The first observations was
reported to be okay, and the last two were saturated.

1.12 Completed WFC 3253 (Optical and UV Observations of Radio Pulsars)

The Wide Field Camera was used to to make one observations of the
Large Magellanic Pulsar. The observations was executed in fine
lock. The observation was received and displayed. It was reported
to look okay.

1.13 Completed HSP/POL 4083 (Remnant Stars in Supernova Remnants)

The High Speed Photometer was used to locate the remnant pulsar
associated with supernova SN1987A. The target acquisition left the
reference star well centered. Both photometric observations were
reported to have proceeded normally.

1.14 Completed FOC/96 4075 (Magellanic Cloud Planetary Nebulae)

The Faint Object Camera was used to make one observation of the
planetary nebulae LMC-N192 which is located in the Large Magellanic
Cloud. The observations was reported to have completed without
incident.

1.15 Uplinked Updated Ephemeris Tables, Per MOSES 2871

1.16 Completed two Sets of FOC/96 4800 (Stellar Content of Wolf-Rayet
Galaxies)

The Faint Object Camera was used to make ultraviolet observations
of the Wolf-Rayet galaxy NGC-1614 to look at its star burst regions
which exhibit broad emission He II lines at 4686 A0. The OSS
monitored the observations and assessed the data a quality. No
problems were reported..

1.17 Completed FOS/BL 4799 (Quasar Absorption Line Survey)

The Faint Object Spectrograph was sued to make an absorption line
survey of quasar PKS0232-04. The observations were executed as
scheduled, and no problems were reported.

1.18 Completed HSP/UV2 1099 (Active Galactic Nuclei)

The High Speed Photometer was used with filter F140LP to observe
variations in the ultraviolet flux of the active galactic nuclei of
galaxy 3CR371. The observations were executed in single star course
track. Recentering occurred during three of the observations , but
did not adversely affect the data. The last two observations showed
a drop in the signal during the observation, probably caused by the
target drifting out of the aperture.

1.19 Completed WFC 1306 (GTO Low Latitude Parallel Program)

The Wide Field Camera was sued to make a series of six low latitude
observations which were taken in parallel with the prime science
observations. The observations were taken in fine lock. The last
two observations were reported to have shown excessive spacecraft
roll, but the images showed no sign of trailing.

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

The High Resolution Spectrograph was used to make of the star
Sirius to obtain WSCAN mode observations to get an accurate flux
distribution and and ultraviolet line profile of the star. The
guide star acquisition for this star failed. This caused the
onboard target acquisition to fail. The observations were all
reported as lost.

1.21 Completed PC 3769 (Structure of Inner Coma of Comet Chiron)

The Planetary Camera was used to make observations of the
comet/object Chiron in order to fine its outer edge (i.e., the
exopause), of the gravitationally bound dust cloud around the
nucleus (i.e., the inner coma), and to look for indications of
active regions within the inner coma. The observations were
executed as scheduled, and no problems have been reported.

2.0 FLIGHT OPERATIONS SUMMARY:

2.1 Guide Star Acquisitions:

The prime acquisitions were missed because there was a V1 axis
error that had been building up thoughtout the day. Through a
procedure error the attitude error was not corrected, and this
affected subsequent observations.
