HUBBLE SPACE TELESCOPE
DAILY REPORT #1000

PERIOD COVERED: 0800 EST
Daily Status Report as of 298/1200Z.

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

1.1 Completed Four Sets of PC 4308 (Snapshot Survey for Companions to
Planetary Nebula Nuclei - Cycle 3 High)

The Planetary Camera was used to make an observation of the central
region of planetary nebula NGC-1514 and NGC-3581. It is possible
that the central staris a double star. The observations was received
and displayed in the OSS, the data was reported to be normal. One
image was reported to look okay, and two were partially saturated.

1.2 Completed GHRS/2 4573 (Boron in Orion: Cycle 3 Medium)

The High Resolution Spectrograph was used to obtain high signal to
noise ratio observations of the O class star HD35299 which is
located in the Orion Nebula. This is to test the theory that Boron
is created by neutrino spallation during a Type II supernova
explosion (ie., SNeII). The observations were received and displayed
in the OSS. No anomalies were reported.

1.3 Completed WFC 5025 (WF/PC Cycle Calibration: Photometric Calibration
Monitor)

The Wide Field Camera and planetary Camera were used to make
observations of the ultraviolet star BD+75D325 using only
single-chip readouts of W2 and P6. Six broad band filters were used.
A total of twelve observations were taken. Where possible the OSS
monitored the observations. All 12 images were reported to look
okay.

1.4 Uplinked Updated Ephemeris Tables, Per MOSES 2871

1.5 Completed Two Sets of PC 5014 (WF/PC Cycle 3 Calibration: PC Flats
Narrow. 2)

The Planetary Camera was used to make standard Earth calibrations
images for flat fielding of PC observations. Medium and narrow
filters were used, with and without neutral density filters. The
observations were executed as scheduled. One image was reported to
be normal, and the second was underexposed.

1.6 Completed FOS BL 4260 (Extreme Stellar Winds and Post Main Sequence
Evolution)

The Faint Object Spectrograph was used to make observations of star
-61D40. This star is believed to be intermediate between a class O
and WR star and to have strong winds and high mass loss rate (i.e.,
much higher than normal O class stars). The onboard target
acquisition did not bracket the target. Nevertheless, the
observations were reported to look okay.

1.7 Completed Two Set of PC 4929 (WF/PC Cycle 2: Improved Dark
Calibration)

The Planetary Camera was used to make two dark calibration images.
The two exposures lasted 1200 seconds each, and the camera was
pre-flashed before the observations. Both observations were reported
to be normal exposures.

1.8 Completed WFC 3589 (Parallel High Resolution Imaging of Defuse
Objects in the Magellanic Clouds)

The Wide Field Planetary Camera was used to make observations of the
nebulous object LMC-N11 which is located in the Large Magellanic
Cloud. This observations was take in parallel with the prime science
observation. Am emission line filter and nearby continuum filter
were used. Two image were received and displayed. They both were
reported to look okay.

1.9 Completed PC 4940 (Post Asymptotic Giant Branch Evolution in the
Magellanic Clouds)

The Planetary Camera was used to make two images of the planetary
nebula LMC-SMP-101 which is located in the Large Magellanic Cloud.
These observations will provide information on the morphology, size,
and dynamically age of the object. Both observations were displayed,
and they were reported to look okay.

1.10 Completed FGS 5118 (Monitor the Long Term Stability of FGS Revised)

FGS #3 was used to measure the position of standard stars OF-102,
and OF-84 to monitor its internal positional stability. The
astrometry was monitored and no problems were seen in the telemetry.

1.11 Completed FOS/RD 4784 (Transition Comet: Search for OH)

The Faint Object Spectrograph was used to make spectral observations
looking for OH emission line at 3085 A0 on the asteroid JOYASTE. The
asteroid has some properties of looking like a comet. The
observations were executed as scheduled,and no problems were
reported.

1.12 Completed Two Sets of PC 4903 (The Nuclei of Nearby S0 and Spiral
Galaxies - II A PC Snapshot Imaging)

The Planetary Camera was used to make snapshot images of the
low-redshift galaxy NGC-1493 to study its surface brightness,
identify sub-arcsecond condensations, look for point sources, and
look for a stellar or gaseous disk and dust lanes. Two observations
were received and displayed in the OSS. No anomalies were reported.

1.13 Completed FOS/RD 4581 (Quasar Absorption Line Survey - Cycle 3
High)

The Faint Object Spectrograph (Red Side) was used to make two
observations of quasar PKS0439-43 to learn more about the origin and
evolution of gas clouds along the line of sight of this target. Both
observations were received and displayed. Several recentering event
were reported. No other anomalies were noted.

1.14 Completed Two Sets of WFC 4381 (HST Medium - Deep Survey - Cycle 3)

The Wide Field Camera was used to make two set of medium-deep high
latitude sky survey observations taken in parallel with the prime
science observations. The observations were executed as scheduled,
and no problems were reported. Four images were received and
displayed. They were reported to look okay.

1.15 Completed FOS/BL 2245 (Ultraviolet Interstellar Polarization)

The Faint Object Spectrograph (Blue Side) was used to make
ultraviolet polarization observations of the reddened earl type star
HD98695. These observations should proved new information about the
composition, size, and shape of the interstellar grains. The OSS
monitored the observations and assessed the data quality. No
anomalies were reported.

1.16 Completed WFC 5076 (WF/PC Cycle 3 Calibration: WFC Flats Wide. 2)

Routine Earth flat calibration exposures were taken with the Wide
Field Camera. The observations were monitored in the OSS, and the
data quality was assessed. No problems were reported.

1.17 Completed FOS/BL 5078 (Spectroscopic Observations of the Exposed
White Dwarfs)

The High Resolution Spectrograph was used to make four observations
of the dwarf nova VW Hyi, which is normally at 13.6 magnitude, but
can get up to 8th magnitude in outbursts. Five observations were
received and displayed. The science observations were reported to
look normal.

1.18 Completed FOC/96 5028 (FOC Objective Prisms - Wavelength
Calibration Verification)

The Faint Object Camera (f/96) was used to make some direct images
and prism observations of symbiotic star RX-PUP. One set of
observations were wavelength calibrations, and an other set were be
a comparison images. The observations were executed as scheduled,
and no problems were reported.

1.19 Completed FGS 4893 (Orbital Motions of Close Binary Stars - cycle 3
High)

Fine Guidance Sensor #3 was used to make astrometric observations of
the binary star system HD88021 to obtain its orbital elements. These
observations are important since most of the estimates of stellar
mass are made by observing elements of these systems. The astrometry
was monitored and the astrometric observations was reported to have
ended with a Stop Flag of FGS #3.

1.20 Completed WFC 4849 (GTO High Latitude Program - Cycle 3 High)

The Wide Field Camera was used to make high latitude sky survey
observations taken in parallel with the prime science observations.
The observations were executed as planned, and no problems were
reported.
