   DAILY REPORT #2502

PERIOD COVERED:  0000Z (UTC) 11/16/99 - 0000Z (UTC) 11/17/99

Daily Status Report as of 321/0000Z

1.0 OBSERVATIONS SCHEDULED AND ACCOMPLISHED:

        Since HST remains in Zero Gyro Sun Point (ZGSP), no science 
observations were performed.

2.0 FLIGHT OPERATIONS SUMMARY:

    2.1 Guide Star Acquisitions:
No activity

    2.2 FHST Updates:
No activity

    2.3 Operations Notes:

        The HST remains in Zero Gyro Sun Point (ZGSP).  Daily meetings are 
being held, and extensive analyses are being performed.

        After the enter orbit day event at 321/0028Z, the vehicle 
experienced another large attitude excursion.  An extensive V2 maneuver was 
required to put the Sun back into the primary coarse sun sensor.  The 
Battery rate of error counter reached a value between 1302 and 1362, prior 
to re-setting.  The safemode limit is now set to 2100.  The EPS reached 
trickle charge in the day pass during the orbit.

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

        GSTDN supports were obtained at Canberra (at 320/1421Z and at 
320/1600Z) and at Goldstone (at 320/2132Z0 in order to dump SSR engineering 
data.

3.0 SIGNIFICANT FORTHCOMING EVENTS:

        Servicing Mission 3A, currently scheduled for December 6, 1999.
