HUBBLE SPACE TELESCOPE
DAILY REPORT #800

PERIOD COVERED: 0800 EST 01/08/93 - 0800 EST 01/11/93

Daily Status Report as of 011/1200Z.

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

1.1 Completed GHRS/2 4217 (Absorption Cross sections of Nearby Galaxies)

The High Resolution Spectrograph was used to make a single spectral
observation of quasar 1341+258. The metal absorption lines in the
quasar are thought to arise from matter associated with intervening
galaxies. The observations was received and displayed. The spectrum
was weak, which was expected because the target was very faint.

1.2 Completed PC 4084 (Globular Cluster Cores, GTO Augmentation)

The Planetary Camera was used to take eight U-band images of the
core of globular cluster NGC-5272 (aka, M-3 located in Canus
Venatici). All of the images were received and displayed. They all
were reported to look okay.

1.3 Completed FOC/48 4740 (Intensifier HV Test)

The high voltage was brought up on the Faint Object Camera (f/48)
for the first time since the intensifier high voltage anomaly of
Sept. 17,1992. The high voltage was turned on just before LOS. At
the AOS the high voltage was off. It was not clear what the problem
was. An HSTAR was written. Seven observations were received and
displayed. They all were blank because the high voltage went off
shortly after it came on. (See Operations Note 2.4)

1.4 Completed PC 4140 (Rapid Internal Monitor)

The Planetary Camera was used to take two internal flat images to be
used to check for new forms of contamination. Both images were
received and displayed in the OSS. They both were reported to look
okay.

1.5 Completed Two Sets of HSP/UV2/POL 3234 (X-Ray Binaries)

The High Speed Photometer was used to make make both photometric and
polarimetric observations of the x-ray binary star HD77581 (aka,
Vela XR-1). 18 observations were taken on the first set. They ware
all received and displayed. Most of them looked okay, four of them
had short term fluctuations significantly higher than the background
noise level. This was apparently due to spacecraft jitter associated
with a terminator crossing.

The second set of 18 observations were also received and displayed.
The first two images were target acquisition images, and showed the
target well centered. The following observations looked good, but
two images were filed as bad because they had some short term
fluctuations similar to those in the first set.

1.6 Completed HSP/UV2 3255 (Optical Variability Associated with Black
Holes)

The High Speed Photometer was used to try and obtain high rate
ultraviolet photometry observations of x-ray binary star A0620-00
whose companion is a suspected black hole. The target acquisition
images were blank. The time series data had low counts.

1.7 Completed WFC 1306 (GTO Low Latitude Parallel Program)

The Wide Field Camera was used to make some low latitude
observations in parallel with the prime science observations. All
observations were received and displayed in the OSS. They were all
reported to be nominal.

1.8 Completed FOS/RD 4212 (Internal Wave Length Calibration)

The Faint Object Spectrograph was used to obtain wave length
calibration images using every dispenser-detector combination. All
observations used internal sources. The observations were received
and displayed, and all were reported to be okay.

1.9 Completed Two Sets of FOC/96 4107 (Search for QSOs Suitable for
Subsequent Observations)

The Faint Object Camera was used to try and obtain images of three
faint quasars (i.e., 1013+00, 0307+0222, and 0058-276B) to see if
they had sufficient ultraviolet flux for future observations. The
observations were received and displayed, however, they were all
reported to be blank.

1.10 Completed FOC/96 3801 (Search to QSOs Suitable for Observation)

The Faint Object Camera Was used to make one ultraviolet observation
of faint high red shift quasar 0938+199. The observations was
received and displayed. The image was blank.

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

The Faint Object Camera was used to make a single image of the
planetary nebula SMC-N67 located in the Small Magellanic Cloud. The
image will be used to measure its diameter. The image was reported
to look good.

1.12 Completed FOS/BL 4110 (The Physics of Massive O Stars)

The Faint Object Spectrograph was used to make six observations of
massive OB class star SK67D211 which is located in the Large
Magellanic Cloud. Ultraviolet spectral observations were taken from
1150 to 2300 A0. All six observations were reported to look okay.

1.13 Completed WFC 1297 (GTO High Latitude Parallel Program)

The Wide Field Camera was used to take a series of four high
latitude images in parallel with the prime science observations. All
four of the images were reported to look okay.

1.14 Completed WFC 4105 (HST Medium Deep Survey: High Latitude)

The Wide Field Camera was used to take a single image as part of a
basic medium-deep sky survey taken in parallel with the primary
science observations. The observations was reported to look okay.

1.15 Uplinked Updated Ephemeris Tables, Per MOSES 2871

1.16 Completed WFC-PC 4109 (Rapid Internal Monitor)

Both the Wide Field Camera and the Planetary Camera were used to make
internal flat images looking for new forms of contamination (i.e.,
daisies and measles). Both images were inspected in the OSS, and
reported to be okay.

1.17 Completed FGS-PC 4765 (Overlapping Plate Field Distortion)

Both the Planetary Camera and Fine Guidance Sensor #3 were used to
measure the optical field angle distortion (OFAD). The Planetary
Camera observations were displayed, and there was at least one star
image in each observation. The astrometry observations were
monitored, and no problems were reported in the telemetry.

2.4 Operations Note:

On Day 008/1926Z The Faint Object Camera (f/48) was powered up to
fulfill a CARD restriction that requires that the FOC Camera P/S to
be cycled every 30 days. This restriction has been waived once due
to the IEHT anomaly that occurred on Sept. of 1992, so it had been a
little over two months since the last cycling event. The IEHT has
been powered up successfully two times since the original failure.
The turn on procedure that was attempted on Day 008 employed the
modified ramp up procedure that was used in previous engineering
tests and appeared to be proceeding nominally as the spacecraft
entered LOS. But at AOS the IEHT telemetry indicated it was powered
off. The implication is that the PDA H/W current limit was tripped,
powering off the IEHT. ESA and STScI engineers are investigating the
anomaly. (See Note 1.3)
