HUBBLE SPACE TELESCOPE

                       DAILY REPORT #2410

PERIOD COVERED:  0000Z (UTC) 07/08/99 - 0000Z (UTC) 07/09/99

Daily Status Report as of 190/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed WF/PC-2 8444 (WF/PC-2 CYCLE-8 Internal Monitor)

       The WF/PC-2 was used to make a bias, and an internal flat, observation
as part of a Cycle-8 monitoring program to monitor the health of the cameras. 
A variety of internal exposures are obtained in order to provide a monitor of
the integrity of the CCD camera electronics in both bays {gain 7 and gain 15},
a test for quantum efficiency in the CCDs, and a monitor for possible buildup
of contaminants on the CCD windows.  The observations were executed as
scheduled, and no anomalies were noted.  

   1.2 Completed Two Sets of STIS/CCD 8408 (STIS CCD Dark Monitor C8)

       The Space Telescope Imaging Spectrograph (CCD) was used to make a CCD
bias calibration observation. This is to monitor the darks for the STIS CCD. 
The observations were executed as scheduled, and no anomalies were reported.  

   1.3 Completed Two Sets of WF/PC-2/STIS/CCD 8267 (Taking the Measure of
Planets in the Globular Cluster 47 Tucanae)

       Both the WF/PC-2 and the Space Telescope Imaging Spectrograph (CCD) were
used to make observations of the globular cluster NGC-104 (a.k.a., Globular
Cluster 47 Tucanae) to search for stars with planetary companions in close
orbits.  HST is uniquely capable of providing the requisite, high-dynamic
range, time-series photometry.  These observations extended over a several day
period.  The observations were executed as scheduled, and no anomalies were
noted.  

   2.0 FLIGHT OPERATIONS SUMMARY:

   2.1 Guide Star Acquisitions: 

                            Scheduled Acquisitions : 2
                                        Successful : 2

                          Scheduled Reacquisitions : 18
                                        Successful : 18

   2.2 FHST Updates: 

                              Scheduled : 2
                             Successful : 2

   2.3 Operations Notes: 

       The flight operation team returned to the STOCC area at 190/0000Z
following the conclusion of GSFC Internal Simulation #7 (EVA-2).  They continue
to operate using the PRS ground system.

       The “Tucanae” proposal continues to be executed with no reported
problems.

       Using ROP SR-1, the SSR EDAC error counter was cleared four times.

       The NICMOS FPA temperature sensor  for detector 2 was enabled at
189/1745Z as directed by an operations request.

3.0 SIGNIFICANT FORTHCOMING EVENTS: 

       Continuation of normal science observations and calibrations.
