PERIOD COVERED:  0000Z (UTC) 07/08/96 - 0000Z (UTC) 07/09/96

Daily Status Report as of 191/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed WF/PC-2 6354 (Measuring Luminosity Evolution in Z =3D =
0.3 Field Galaxies)

       The WF/PC-2 was used to make snapshot observations of the galactic =
cluster Gal-Cluster-1 located at a distance of Z =3D 0.3.
The targets were drawn from a much larger pool of galaxies for which the =
internal kinematics have been measured from an extensive ground based =
program. A status buffer error message was received at 190:02:25:47Z =
which indicated that a failure of the FOS/RD binary target acquisition =
scheduled for 02:20:56Z. No other anomalies were noted.

   1.2 Completed FOS/RD 6801 (C and N Production and Pollution Mechanism =
in Low-Metallicity)

       The Faint Object Spectrograph (Red side) was used to make =
spectrographic observations of the dwarf galaxy UM469 to measure its N, O =
and C emission lines in its H II regions. The observations were completed =
as planned and no anomalies were reported.

   1.3 Completed Three Sets of 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.

   1.4 Completed GHRS/1/2 6594 (White Dwarf Companions of Barium and CH =
Peculiar Stars)

       The High Resolution Spectrograph (Sides One and Two ) were used to =
attempt to make spectrographic observations of the white dwarf of the =
Barium and CH Peculiar class star HD16458-B. This will test the theory =
that abundance anomalies in this star caused by mass transfer from the =
precursor of the white dwarf. The observations were executed as =
scheduled, and no anomalies were noted.

   1.5 Completed COSTAR/U 6895 (FOC Cycle 6 PSF Monitoring)

       The Faint Object Camera/Costar were used to make observations of =
object 01-001 (aka, white dwarf star BPM16274) in order to check out the =
Point Spread Function (PSF) and focus of the system. The COSTAR DOB was =
moved 3.0 microns and was completed at 190/1354Z. The current position is =
-0.65 mm. The observations were executed as scheduled, and no problems =
were reported.

   1.6 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.

   1.7 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.

   1.8 Completed FOS/BL 6465 (The UV Upturn of Super-Metal-Rich Globular =
Clusters)

       The Faint Object Spectrograph (Blue Side) was used to make =
ultraviolet spectrographic observations of the super-metal-rich globular =
cluster NGC-224-G17 which is located within the Andromeda Galaxy (aka, =
M-31) in order to observe the spectral energy distribution of this =
cluster. The objective is to determine whether the strong ultraviolet =
fluxes seen in the galaxy can also be seen in this cluster. The =
observations were executed as  scheduled, and no problems were reported 

2.0 FLIGHT OPERATIONS SUMMARY:

   2.1 Guide Star Acquisitions: 

                            Scheduled Acquisitions : 4
                                        Successful : 4

                          Scheduled Reacquisitions : 12
                                        Successful : 12

   2.2 FHST Updates: 

                              Scheduled : 9
                             Successful : 9

   2.3 Operations Notes: 

Normal operations, no problems to report.

The COSTAR DOB was moved 3.0 microns and was completed at 190/1354Z. The =
current position is -0.65 mm, next move will nominally take place in =
October or November of this year and will be synchronized with a =
secondary mirror move.

3.0 SIGNIFICANT FORTHCOMING EVENTS: 

        Nothing at this time.
