HUBBLE SPACE TELESCOPE
DAILY REPORT #1099

PERIOD COVERED: 0700 EST
Daily Status Report as of 080/1200Z.

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

1.1 Completed Three Sets of WF/PC-2 5476 (Continuum Snapshots of 3CR
Radio Galaxies)

The WF/PC-2 was used to make snapshot images of radio galaxies
3C79.0, 3C154.0, 3C191.0, 3C98.0, and 3C198.0 as part of a continuum
survey and to study the galaxies' morphology. Twelve images were
received and displayed. Except for a few recentering events, the
observations were reported to be okay. Two images were reported to
show the target at the edge of the pyramid, and straddling two
chips.

1.2 Completed Two Sets of WF/PC-2 5560 (WF/PC-2 Cycle 4 Calibration:
Internal Monitor. 1)

The WF/PC-2 was used to make several internal bias, K-Spot, and
flat calibration observations to monitor the CCD camera electronics,
the optical alignment, and for contamination. A total of ten images
were taken, and they all were reported to be okay.

1.3 Completed WF/PC-2 5104 (Peculiar and Interacting Galaxies (WC01):
Cycle 4)

The WF/PC-2 was used to make images of galaxy 3C405. The OSS
monitored the observations, and assessed the data quality. Six
images were received and displayed. Except for a few recenterings
which did not apparently affect the image quality, they all were
okay.

1.4 Completed FOC/96 5524 (FOC Prism Wavelength Calibration: Cycle 4)


The Faint Object Camera (f/96) was used to attempt to obtain an
objective prism dispersion curve observation using ultraviolet
standard star SAND-3 which has an extensive emission line spectrum.
Two observations were received and displayed. The target was not
visible in the first observation, and on the second it was reported
to be at the very edge of the frame. The observation status was
listed as failed.

1.5 Completed Three Sets of WF/PC-2 5370 (HST Medium_Deep Survey: Cycle
4 Medium, High Galactic Latitude)

The WF/PC-2 was used in parallel with the prime science observations
to make high galactic latitude observations as part of a medium-deep
sky survey. The main purpose of these observations is to study the
evolution and structure of galaxies. Six observations were received
and displayed in the OSS. One image was reported to show a small but
sharp change in bias levels in chip PC1. No other anomalies were
noted.

1.6 Completed Four Sets of FOC/96 5525 (FOC Neutral Density Filter
Transmission)

The Faint Object Camera (f/96) was used to make internal flat
calibration images using the blue LED to measure its transmission
curve. F1, F2, and F4 neutral density filters were used. All four
observations were received and displayed. They were reported to be
nominal.

1.7 Completed FGS 5331 (Linking HIPPARCOS to the Extragalactic Reference
Frame FT0-11, Part 7)

Fine Guidance Sensor #3 was used to make astrometric observations of
star 0851+202IN and nearby extragalactic objects which are known to
have a small angular separation. The observations were monitored.
The targets were numbered as they were visited. Target 1 ended up
with a STOP flag and Search Radius Limit Exceeded Flag. Target 2-5
were locked onto and were held without problems. Target 1 was
revisited, and again received a STOP flag. Targets 5, 4, 3, and 2
were revisited, and again they were locked onto it and held. Target
1 was visited for the last time, and this time it was successfully
locked onto and held.

1.8 Completed WF/PC-2 5570 (WF/PC-2 Cycle 4 Calibration: Earth Flats,
Large Set)

The WF/PC-2 was used to make a set of Earth flat calibration images
using different filters in order to construct high quality flat
fields of the OTA illumination pattern. A total of eight images were
received and displayed. Two images were reported to be underexposed,
two were saturated, and four were okay.

1.9 Completed WF/PC-2 5392 (Mapping Io's Surface and Volcanic Activity:
Cycle 4 Medium)

The WF/PC-2 was used to make images of the surface of Jupiter's moon
Io
to study changes since the Voyager Mission and before the Galileo
Mission. The images were reported to be nominal. Four images were
received and displayed. A fifth image still remains on the science
tape recorder, and will be analyzed later.

1.10 Completed Two Sets of FGS 5336 (Linking HIPPARCOS to the
Extragalactic Reference Frame, NEWHIP-B)

The Fine Guidance Sensor #3 was used to make two sets of
astrometric observations of various objects. These objects
lie near the apparent position of extragalactic objects. These
objects will also be observed with the HIPPARCOS satellite. This
data will be used to determine the systematic rotational offset of
the reference frame of the HIPPARCOS astrometric satellite. The
observations were executed as scheduled. No anomalies were reported.

1.11 Completed FGS 5174 (Astrometric Companion Search: Cycle 4)

FGS #3 was used to make astrometric observations of the possible
binary dwarf star BD+67D552 to look for an astrometric unseen low
mass companion. The OSS monitored the observations and assessed the
data quality. No anomalies were noted.

1.12 Completed Two Sets of WF/PC-2 5091 (GTO High Latitude Parallel
Program: Cycle 4)

The WF/PC-2 was used in parallel with the prime science observations
to make high galactic latitude observations greater than +/-30
degrees. These are randomly chosen fields to sample very low
luminosity stars in the solar galactic neighborhood, galactic halo
objects, and distant galaxies. Four images were received and
displayed. The first two observations encountered some recentering
events, but were reported to be okay. The last two observations were
nominal.

1.13 Completed WF/PC-2 5612 (SMOV WF/PC-2 Decontamination)

The WF/PC-2 was used to do decontamination operations. Observations
of standard A+81D266, and K-Spot observations were also taken. A
total of nine observations were monitored and displayed. No
anomalies were noted.

1.14 Completed WF/PC-2 5484 (Understanding the Geminga (1E0630+178)
Optical Counterpart: Cycle 4 High)

The WF/PC-2 was used to make observations of the X-Ray/ Gamma-Ray
source known as Geminga (aka, 1E0630-178) to study its distance
and physical characteristics of its emissions. The observations were
executed as scheduled, and no anomalies were noted.

1.15 Completed Two Sets of FOC/96 5140 (Observations of the Narrow Line
Regions in Nearby Seyfert Galaxies)

The Faint Object Camera (f/96) was used to make observations at
several different wavelengths of Seyfert galaxies MRK-78 and MRK-3
which are located near the Cygnus A source. This is to study
relations between the radio and optical emissions. The OSS monitored
the observations, and assessed the data quality. Four images were
reported to be okay, and one image was underexposed.

1.16 Completed GHRS/2 5506 (The Deuterium Abundance in Moderate Redshift
QSO Systems)

The High Resolution spectrograph was used to make observations of
QSO 0454-220. A wavelength calibration image was also made. A total
of five observations were received and displayed. Some recentering
events were reported after a day/night transition. No other
anomalies were noted.

1.17 Completed WF/PC-2 5092 (GTO Low Latitude Parallel Program: Cycle 4)

The WF/PC-2 was used to make observations taken in parallel with the
prime science observations. This is part of a survey to take
pictures of a large number of fields within 30 degrees of the
galactic plan. The intent is to determine the luminosity function of
low mass stars and the mass density in the solar neighborhood. The
images were received as scheduled, and they were reported to look
okay.

1.18 Completed WF/PC-2 5563 (WF/PC-2 Cycle 4 Photometric Calibration
Monitor 1: UV/OPT STD.)

The WF/PC-2 was used to make photometric calibration images of
ultraviolet standard star GRW+70D582, and to monitor the photometric
stability and quantum efficiency of the WF/PC-2. A SIP corrective
maneuver was successfully uplinked to the spacecraft. Seventeen
images were reported to look okay, except for one image in which the
target looked elongated. No other anomalies were noted.

1.19 Completed GHRS/2 5545 (GHRS Side Two Pulse Height Analysis/Ion
Test: Cycle 4)

The High Resolution Spectrograph (Side Two) was used to run a
standard pulse height analysis (PHA) test on the detectors. This was
an internal observation, which was used to measure the diode
response as a function of threshold setting. The OSS monitored the
observations and assessed the data quality. No anomalies were noted.
