HUBBLE SPACE TELESCOPE
   DAILY REPORT #2504

PERIOD COVERED:  0000Z (UTC) 11/18/99 - 0000Z (UTC) 11/19/99

Daily Status Report as of 323/0000Z

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 spacecraft remains in Zero Gyro Sun Point (ZGSP) with all 
subsystems operating nominally.

        The SSR EDAC error counter was cleared once using ROP SR-1.

        GSTDN sites (Canberra at 322/1259Z and 323/0144Z, and Mila at 
322/1707Z and 322/1850Z) were used to dump engineering data.  More GSTDN 
coverage has been scheduled for today.

        According to HSTAR 7364, the parameter QCOPISRE read failed at 
322/165648Z, near the acquisition of signal while a dump was being 
performed.  Later, DF-224 LMU-7 memory was successfully dumped at 322/1957Z.

        At 32/1727Z, the following safing tests were disabled: the Body 
Rate Low Mode, the Body Rate High Mode, the RWA Speed Limit, the PSEA Power 
Supply, the Valid Ephemeris/Magnetic Field Model Check, the Solar Array 
Position Limit, the Sun Angle/Solar Array Normal, the Lack of STOCC 
Commands, the SPC List Exhaustion, the Spin Stabilized Power On, and the 
Earth/Moon/Bright Object.

3.0 SIGNIFICANT FORTHCOMING EVENTS:

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