       DAILY REPORT #3070

PERIOD COVERED:  0000Z (UTC) 03/11/02 - 0000Z (UTC) 03/12/02

Daily Status Report as of 071/0000Z

1.0 OBSERVATIONS SCHEDULED AND ACCOMPLISHED:

        Science operations are scheduled to begin at approximately 
071/0122Z, just after the period of this report.

2.0 FLIGHT OPERATIONS SUMMARY:

    2.1 Guide Star Acquisitions:
       Scheduled Acquisitions:  5
    Successful:  5

  Scheduled Re-acquisitions:  0
    Successful:  0

    2.2 FHST Updates:
    Scheduled: 12
    Successful: 12

    2.3 Operations Notes:

        All HST subsystems are reported to be in a nominal state.  The 
Science Instruments are all out of safe and awaiting resumption of 
post-SM3B verification and normal science.

        Per operations requests, the following actions were taken:
         A gyro bias update at 070/1612Z.
         An adjustment of SM3B limits at 070/1702Z.
         An attitude reference update at 070/1830Z.
         Gyro #6 was powered off at 070/2204Z.  Gyro 6 limits were then 
adjusted.

        Using ROP DF-10A, a 486 safeware/table dump was made at 070/1715Z.

        SSR-1 uncorrectable EDAC errors were cleared at 070/1934Z per ROP 
SR-9A.

        An engineering status buffer limit (SESBSLD=1) was modified at 
071/0221Z, using ROP DF-18A.

        At 071/025129Z, during a guide star acquisition, QSFGENB0 (Saved 
FGS Error Null Bias 0) and QFGENB0 (FGS error null Bias 0) flagged 
out-of-limits low.  HSTAR 8548 was written.

        As documented in HSTAR 8549, the NICMOS Cooling System CPL radiator 
B temperature (MNCRADBT) flagged out-of-limits low with a value of -68.33 , 
the NICMOS Cooling System CPL Htex2 temperature (MNCHX1T) flagged low at 
-63.33, and the NICMOS Cooling System CPL Radiator A temperature (MNCRADAT) 
flagged low at -68.165.  All occurrences were from 071/051558Z to 071/052748Z.

        During the WF/PC-2 decontamination, the limits were managed at 
071/0803Z per an operations note.

3.0 SIGNIFICANT FORTHCOMING EVENTS:

        Commencement of Servicing Mission Orbital Verification (SMOV) 
activities and the eventual continuation of normal science observations and 
calibrations.
