DAILY REPORT #1453

PERIOD COVERED: 0000Z (UTC) 08/11/95 - 0000Z (UTC) 08/14/95

Daily Status Report as of 226/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

1.1 Completed FGS 6047 (Calibrating the Mass Luminosity Relation at the
End of the Main Sequence)

The FGS were used to make astrometric observations of star G250-29AB
as part of a study to determine its mass luminosity relationship. The purpose
is to measure the precise parallax and relative orbit of its faint companion.
The observations were completed as planned, and no problems were reported.

1.2 Completed Two Sets of WF/PC-2 6253 (Pure Parallel Archive Program)

The WF/PC-2 was used to execute a pure parallel program taking
ultraviolet observations running concurrent with prime science observations.
The intent is to search for extra-galactic sources with flux excesses at 3000
A0 and galactic sources with excesses at 1600 A0. The observations were
completed as planned, and no problems were reported.

1.3 Completed FGS 6238 (Companion to GL6230)

The FGSs were used to make POS and TRANS mode astrometric observations
of star GL623 (aka, Gleise 623) looking for possible companions. Five other
reference stars were also used. From these data the precise parallax,
barycentic orbits, and accurate masses of the star and its companion will be
determined. The observations were completed as schedule, and no anomalies
were reported.

1.4 Completed WF/P-2 6254 (GTO Pure Parallel Program - Cycle 5)

The WF/PC-2 was use to make random long exposures of high galactic
fields taken in parallel with the prime science observations to obtain a
random sample of galaxies. The observations were executed as scheduled, and
no anomalies were noted.

1.5 Completed Two Sets of WF/PC-2 5974 (The Evolution of Radio Loud
Quasars)

The WF/PC-2 was used to make observations of the radio loud large
redshift quasars MRC0133-26 and MRC1311-27. The purpose is to determine if
these galaxies are from the same parent population as other kinds of radio
galaxies already studied using HST. The observations were completed as
scheduled, and no problems were reported.

1.6 Completed Four Sets of WF/PC-2 6119 (Snapshot Survey for Companions of
Planetary Nebula Nuclei)

The WF/PC-2 was used to make snapshot survey observations of planetary
nebulae A66, A65, NGC-2792 and NGC-2022 to study their nuclei and to look for
possible companions. The observations were executed as scheduled, and no
anomalies were noted.

1.7 Completed WF/PC-2 6133 (The Most Massive Stars in the Magellanic
Clouds)

The WF/PC-2 was used to make observations of star SK-67D167 which is
known to be one of the most massive stars in the Magellanic clouds (maybe up
to 200 solar masses). It is not clear whether or not these objects are single
stars. The observations were completed as planned, and no problems were
reported.

1.8 Completed FOS/BL 6023 (Observation of OH in the Mars/ Phobos Neutral
Cloud)

The Faint Object Spectrograph (Blue Side) was used to make
spectrographic observations of the neutral gas torus cloud in the region of
Mars' moon Phobos looking for OH. Water from the surface of Phobos will
quickly dissociate into OH + O. The observations were completed as planned,
and no problems were reported.

1.9 Completed Four Set of WF/PC-2 6189 (WF/PC-2 Cycle 5 Calibration:
Internal Monitor - Vis Flats)

The WF/PC-2 was used to make internal visual flat calibration images.
Both photometric and narrow-band filters were used. The observations were
executed as planned, and no problems were reported.

1.10 Completed Two Sets of WF/PC-2 6190 (WF/PC-2 Cycle 4 Calibration:
Internal Flats)

The WF/PC-2 was used to make an internal flat filter sweep and an
internal preflash level test. The internal lamp is also used as a source for
the preflash test. The observation was executed as scheduled, and no
anomalies were noted.

1.11 Completed WF/PC-2 5930 (WF/PC-2 Imaging of Intermediate Redshift
Radio Galaxies.)

The WF/PC-2 was used to make observations of the intermediate redshift
radio galaxy 3C460.0. The target is known to exhibit significant structure on
the sub-arcsecond scale. Both line and continuum filters were used. The
observations were completed as planned, and no anomalies were reported.

1.12 Completed GHRS/1 5895 (The Cool Atomic and Molecular Medium in B3)

The High Resolution Spectrograph (Side One) was used to make
observations of star HD22951 in order to study the foreground cool atomic and
molecular medium of a molecular cloud known as B3. These observations should
yield information about the gas pressure, density, kinematics, and chemical
processes in the halo around the cloud. The observations were executed as
scheduled, and no problems were reported.

1.13 Completed Four Sets of WF/PC-2 5957 (Snapshot of 3CR Radio Galaxies)

The WF/PC-2 was used to make observations of radio galaxies 3C381.0,
3C292.0, 3C321.0 and 3C280.0 to study the morphology of these radio galaxy.
The observations were executed as scheduled, and no anomalies were noted.

1.14 Completed WF/PC-2 5913 (Low Mass Binaries and the Luminosity
Function. )

The WF/PC-2 was used to make observations of the low mass binary star
system NGP006 ( A late-type M class dwarf) to study the local stellar
luminosity function. The observations were executed as scheduled, and no
anomalies were noted.

1.15 Completed GHRS/1 5877 (The 11B to 10B Ratio in the Interstellar
Medium.)

The High Resolution Spectrograph (Side One) was used to make
spectrographic observations of the bright star HD143275 in order to study the
foreground interstellar medium. This is to measure the abundance ratio of two
boron isotopes. The observations were completed as planned, and no problems
were reported.

1.16 Completed WF/PC-2 6310 (A Photometric Search for Planets of Nearby
Stars)

The WF/PC-2 was used to make photometric observations of the nearby
star HD128620 and HD128621 (aka, the Alpha, Beta Cent and Proxima Cent
Complex) looking for possible planets. The exposure times were calculated so
that areas beyond ~1.2 arc seconds from the central stars will not be
saturated. The observations were completed as planned, and no problems were
reported.

1.17 Completed FGS 6263 (Parallax of Delta Cephei)

The FGS were used to make astrometric observations of the variable
star Delta Cephei to measure its parallax distance. Delta Cepheid is a
prototypical Cepheid variable star. HST observations could reduce the
uncertainty of its distance to 15%. The observations were completed as
planned, and no problems were reported.

1.18 Completed GHRS/1 5866 (NLTE Spectral Analysis of PG1159 Type Stars)

The High Resolution Spectrograph (Side One) was used to make a NLTE
spectrographic analysis of STAR-1424 to study the GW Vir instability strip
and the photospheric parameters and composition. The observations were
completed as planned, and no problems were reported.
