                       DAILY REPORT #1489

PERIOD COVERED:  0000Z (UTC) 10/03/95 - 0000Z (UTC) 10/04/95

Daily Status Report as of 277/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed WF/PC-2 6250 (WF/PC-2 Cycle 5 Calibration: Internal Monitor)

       The WF/PC-2 was used to make a series on internal calibration
observations.  Internal flats, biases, and K-Spot calibration images were
taken.  These observations are designed to monitor the health of the cameras.
 The observations were executed as scheduled, and no anomalies were noted.

   1.2 Completed GHRS/2 5860 (Detection of ^11B/^10B and Galactic Chemical
Evolution)

       The High Resolution Spectrograph (Side Two) was used in the Echelle
Mode to make spectrographic observations of star HD76932 to study the
isotope-split Boron-11 and Boron-10 lines at 2090 A0.  A wavelength
calibration observation was also taken.  About an hour after this 15-hour
proposal began, at 276/020808Z, there was a one-minute, 50-second loss of
lock that was reported in yesterday's report and in HSTAR 5315.  No other
problems were reported.

   1.3 Completed Two 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.

   1.4 Completed WF/PC-2 and FOS/RD 5976 (Herbig-Haro Object Near the Orion
Nebula)

       The WF/PC-2 was used to make observations of NGC-1976 (aka, M-42, The
Orion Nebula.) looking for possible Herbig-Haro objects.  The images will be
used to determine the excitation mechanisms of the HH objects, and their
interaction with the nebula and cloud gas.  The observations were completed
as plan, and no anomalies were reported.

   1.5 Completed Two Sets of WF/PC-2  5911 (Massive Star Formation in M-31)

       The WF/PC-2 was used to make observations in the northeast spiral arm
of NGC-224 (aka, M-31, The Andromeda Galaxy) looking for indications of
massive star formation.  The observations were made using several different
filters.  The observations were completed as scheduled, and no anomalies were
reported.

   1.6 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 MT009 (a late-type M class dwarf) to study the  local stellar
luminosity function.  The observations were executed as scheduled, and no
anomalies were noted.

2.0 FLIGHT OPERATIONS SUMMARY:

   2.1 Guide Star Acquisitions: 

                            Scheduled Acquisitions : 8
                                        Successful : 8

       One acquisition, at 277/035441Z, failed to fine lock 
       back-up on FGS-1 only.  HSTAR 5319 was written to
       document the event.

       There were four cases when the FGSs experienced loss
       of lock.

                          Scheduled Reacquisitions : 7
                                        Successful : 7

2.2 FHST Updates: 

                              Scheduled : 15
                             Successful : 15

   2.3 Operations Notes: 

       There was one instance of data inversion during STGT
       operations.  A TTR was written.

       Another TTR was written because there was no RF or
       command link to the HST for 21-minutes, 31-seconds due 
       to software problems at STGT.  Services were re-
       scheduled, and the STR suffered no loss of data. 
       There was some loss of engineering data due to the re-
       scheduling, however.

3.0 SIGNIFICANT FORTHCOMING EVENTS: 

        Nothing at this time.
