PERIOD COVERED:  0000Z (UTC) 09/11/95 - 0000Z (UTC) 09/12/95

Daily Status Report as of 255/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed Four Sets of WF/PC-2 6188 (WF/PC-2 Cycle 5 Calibration:
Dark)

       The WF/PC-2 was used to make internal dark calibration images.  The
observations were completed as scheduled, and no problems were reported.

   1.2 Completed GHRS/2 5875 (Hot Winds in T-Tuari Stars)

       The High Resolution Spectrograph (Side Two) was used to make
observations of the star T-Tauri in order to study its hot winds.  This star
is known to have one diskless pre-main sequence star as a companion.  A
wavelength calibration image was also taken.  The observations were executed
as scheduled, and no anomalies were noted.

   1.3 Completed FOS/BL 5948 (Damped Lyman Alpha Absorption Lines in Moderate
Redshifted Galaxies)

       The Faint Object Spectrograph (Blue side) was used to make
observations of the moderate redshift galaxy FSB1047+55 to study its damped
Lyman Alpha absorption lines.  The observations were executed as scheduled,
and no anomalies were reported.

   1.4 Completed FOC/96 6330 (FOC/48 Format Dependent Background Emission And
Geometric Distortion)

       The Faint Object Camera (f/48) was used to make calibration
observations to study the format dependent background emissions (aka, flare)
and geometric distortions.  Internal flats and dark calibration images were
also taken.  The observations were completed as scheduled, and no anomalies
were noted.

   1.5 Completed FGS 6175 (Three Points of Light Calibration)

       The FGSs were used in the Trans Mode to make reference transfer
function astrometric observations of standard star UPGREN69 to make a three
points of light calibration.  Observations were made using three different
filters at three different locations in the "pickle".  The observations were
completed as planned, and no anomalies were reported.

   1.6 Completed WF/PC-2 5971 (HST Medium Deep Survey)

       The WF/PC-2 was used to make a long exposure medium deep sky survey
observations at latitudes larger than 10 degrees taken in parallel with the
prime science observations.  The observations were executed as scheduled, and
no anomalies were noted

   1.7 Completed FGS 6063 (Continuation of Mass Ratio Determination for
Doubles)

     The Fine Guidance Sensors were used to make POS and TRANS mode
astrometric observations of double star L722-22-00.  This binary star system
contains a low mass star and a brown dwarf.  The observations were completed
as scheduled, and no anomalies were noted.

   1.8 Completed 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.

   1.9 Completed Two Sets of WF/PC-2 5760 (The Search for Super Planets
Around Weak T-Tauri Stars)

       The WF/PC-2 was used to make I-Band observations of T-Tauri Class star
HBC407 in order to search for possible super planets by looking for thermal
radiation from the planets in orbit around this star.  The observations were
completed as scheduled, and no problems were reported. 

   1.10 Completed WF/PC-2 5998 (The Evolution of Massive Stars: Closing the
Loop Observationally)

       The WF/PC-2 was used to  make observations of (OB Class) massive star
M-31-Field 1.0 which is located in the Andromeda galaxy.  The goal is to
study the evolution of this class of massive stars.  The observations were
executed as scheduled, and no anomalies were noted.

   1.11 Completed WF/PC-2 5957 (Snapshot of 3CR Radio Galaxies)

       The WF/PC-2 was used to make observations for radio galaxy 3C452.0 to
study the morphology of the radio galaxy.  The observations were executed as scheduled,
and no anomalies were noted.

   1.12 Completed FOS/BL 5928 (Hidden QSOs in "Warm" Infrared Ultraluminaous
Galactic Nuclei)

       The Faint Object Spectrograph (Blue Side) was used to make
spectropolarimetric observations of active galactic nuclei IR1402+43 to look
for "warm" infrared ultra luminous galactic nuclei.  Spectropolarimetry of
this object was done from the ground at varying optical wavelengths, and the
ultraviolet observations with HST are needed to distinguish between the
different mechanisms producing the polarization.  The observations were
completed as planned, and no problems were noted.

2.0 FLIGHT OPERATIONS SUMMARY:

   2.1 Guide Star Acquisitions: 

                            Scheduled Acquisitions : 10
                                        Successful : 10

                          Scheduled Reacquisitions : 5
                                        Successful : 5

   2.2 FHST Updates: 

                              Scheduled : 20
                             Successful : 20

   2.3 Operations Notes: 

       There was a nine minute late acquisition of 
       recoverable realtime engineering data due to a 
       probable scheduling error.

       On DOY 253, a DF-224 SPC load was inadvertently
       uplinked early. As a result, one WF/PC-2 observation
       and some ETR data were lost. (HSTAR 5283)

3.0 SIGNIFICANT FORTHCOMING EVENTS: 

        Nothing at this time.
