PERIOD COVERED:  0000Z (UTC) 09/12/96 - 0000Z (UTC) 09/13/96

Daily Status Report as of 257/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed FOS/RD 6925 (FOS Observations of Solar Analog Standards)

       The Faint Object Spectrograph (Red Side) was used to make absolute =
spectrophotmetry observations of the solar analog star P041-Cali in the =
spectral range of 2200 A0 to 8500 A0.  The objective is to provide the =
primary standards for the absolute calibration of the NICMOS.  The =
observations were completed as scheduled, and no problems were reported.

   1.2 Completed WF/PC-2 6802 (Cosmology With the Medium Deep Survey)

       The WF/PC-2 was used to make observations taken in parallel with =
the prime science observations as part of the Medium Deep Sky Survey.  =
The observations were executed as scheduled, and no problems were =
reported.

   1.3 Completed WF/PC-2 6344 (Low - Mass Binaries in the Hyades - Complet=
ing the Survey)

       The WF/PC-2 was used to make observations of the low mass binary =
star RHY260 (M-Class Dwarf Stars) which is located in the Hyades Cluster. =
 The observations were executed as scheduled, and no anomalies were =
noted.

   1.4 Completed FGS 6764 (Detection and Mass Determination of Low Mass =
Companions)

       The FGS were used in both the TRANS and POS modes to make =
astrometric measurements of nearby, dwarf, M class star GL791 in order to =
measure the mass of its possible low mass companion.  The intent is to =
improve the mass-luminosity relation for the cool end of the main =
sequence.  The observations were executed as scheduled, and no anomalies =
were noted. 

   1.5 Completed Three 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 concurrently 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.

   1.6 Completed FOS/BL/GHRS/1 6448 (Ultraviolet Mapping of the Unique =
Polar HU-Aqr)

       The Faint Object Spectrograph (Blue Side) and the High Resolution =
Spectrograph (Side One) were both used to make ultraviolet spectrographic =
observations of the unique, polar, eclipsing, magnetic, cataclysmic, star =
HU-Aqr.  Observations will be made during all phases of the binary =
system.  The observations were executed as scheduled and no anomalies =
were noted.

   1.7 Completed Two sets of WF/PC-2 6610 (WF/PC-2 Lyman-Alpha Imaging of =
Galaxy cluster at Z =3D 2.4)

       The WF/PC-2 was used to make observations of an apparent blank =
field of view hoping to make Lyman-Alpha observations of faint galaxies =
located at a distance of Z =3D 2.4.  Earlier exposures revealed many =
compact Lyman-Alpha emitters at this distance.  These observations were =
executed in parallel with the prime science observations.  The =
observations were completed as planned, and no problems were reported. 

   1.8 Completed Two sets of WF/PC-2 6909 (WF/PC-2 Cycle 6 Calibration: =
Earth Flats)

       The WF/PC-2 was used to make observations of the bright earth to =
obtain streak flats which are used to construct high quality flat fields =
for the WF/PC-2 filter set.  The observations were executed as scheduled, =
and no anomalies were noted.

   1.9 Completed FOS/RD 6577 (An Expanded Survey for Study of the =
Lyman-Alpha Line and QSO Mg II Absorption)

       The Faint Object Spectrograph (Red side) was used to make =
observations of the UM675 in order to make a survey of the Lyman-Alpha =
line and the 68 Mg II absorption line system.  At 256/1713Z during AOS =
after a ZOE the guide star acquisition was in fine lock backup on FGS #1 =
only.  The Take-Data-Flag was up and no error were indicated. The =
observations were completed as scheduled, and no other anomalies were =
reported. 

   1.10 Completed GHRS/2 6541 (Interstellar Cadmium: Probing Galactic =
Chemical Evolution)

       The High Resolution Spectrograph (Side Two) was used to make =
spectrographic observations of the O/B class star HD57061 HD57061 in =
order to probe interstellar Cadmium and study the galactic chemical =
evolution.  The observations were completed as planned, and no problems =
were reported.

   1.11 Completed FGS 6873 (Parallaxes of Hyades Cluster Members, Cycle 6 =
- High)

       The FGSs were used to make parallax astrometric observations of =
the star PCEN383 and several other reference stars within the Hyades star =
cluster.  When the data from this cycle is combined with previuosly =
obtained data, the population 1 zero age main sequence will be better =
defined.  The observations were completed as scheduled, and no anomalies =
were reported. 

   1.12 Completed FGS 6874 (Parallaxes of Hyades Cluster Members, Cycle 6 =
- High)

       The FGSs were used to make parallax astrometric observations of =
the star VA645 and several other reference stars within the Hyades star =
cluster, to better define the Population 1 zero age main sequence.  The =
observations were completed as planned, and no problems were reported.
