PERIOD COVERED:  0000Z (UTC) 09/18/95 - 0000Z (UTC) 09/19/95

Daily Status Report as of 262/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed WF/PC-2 6184 (WF/PC-2 Cycle 5 Photometric Calibration
Monitor UV/Opt STD)

       The WF/PC-2 was used to make ultraviolet and optical calibration
images of standard star GRW+70D582.  The purpose is to monitor the
photometric stability and quantum efficiency of the WF/PC-2 from the far
ultraviolet to the near-IR.  During these observations, after a successful
FGS reacquisition at 261/112243Z, there were at least three losses of lock,
with the take data flag going down in each instance.  HSTAR 5294 describes
the events.  There were no other reported problems.

   1.2 Completed Two Sets of WF/PC-2 5353 (Low-Mass Binaries in the Hyades:
Cycle 4 High)

       The WF/PC-2 was used to make images of the low-mass, late M-Class
dwarf stars RHY199 and RHY115 which are located in the Hyades cluster.  Some
of the companion stars may be brown dwarfs.  The observations were completed
as scheduled, and no problems were reported. 

   1.3 Completed 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.

   1.4 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 MRC2257-27 and MRC2256-21.  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.

   1.5 Completed GHRS/2 6077 (Boron Abundances in Orion and Boron Production
in Type II Supernovae)

       The High Resolution Spectrograph (Side Two) was used to make
spectrographic observations of the young star HD36285 which in the Orion OB1
association to measure the abundance of boron.  The observations were
executed as scheduled, and no anomalies were noted.

   1.6 Completed GHRS/2 5869 (Chromospheric Activity in Quiet stars: Halo
Subdwarfs)

       The High Resolution Spectrograph (Side Two) was used to make
spectrographic observations of the quiet star HD19445 to study its
chromospheric activity.  This is a search for Mg II emission in low
metallicity solar temperature field stars in the galactic halo.  The
observations were completed as planned, and no problems were reported.

   1.7 Completed WF/PC-2 5978 (Host Galaxy of Distant Radio Quasars)

        The WF/PC-2 was used to make observations of the host galaxy of
distant radio-loud quasar 3C455.0.  The observations were executed as
scheduled, and no anomalies were noted.

   1.8 Completed 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
nebula NGC-6804 to study its nuclei and to look for possible companions.  The
observations were executed as scheduled, and no anomalies were noted.

   1.9 Completed GHRS/1 5859 (Major NLTE Corrections to HST Boron
Observations?)

       The High Resolution Spectrograph (Side One) was used to make
spectrographic observations of star HD61421 (aka, Procyon) to study its boron
(B II) abundances.  The observations were completed as scheduled, and no
problems were reported 

2.0 FLIGHT OPERATIONS SUMMARY:

   2.1 Guide Star Acquisitions: 

                            Scheduled Acquisitions : 12
                                        Successful : 12

                          Scheduled Reacquisitions : 6
                                        Successful : 6

       There were several losses of lock after the
       successful reacquisition at 261/112243Z.  HSTAR 5294 
       was written to document these events.

   2.2 FHST Updates: 

                              Scheduled : 25
                             Successful : 25

   2.3 Operations Notes: 

       There were no significant operational problems 
       encountered

3.0 SIGNIFICANT FORTHCOMING EVENTS: 

        Nothing at this time.
