HUBBLE SPACE TELESCOPE

   DAILY REPORT #2534

PERIOD COVERED:  0000Z (UTC) 01/06/00 - 0000Z (UTC) 01/07/00

Daily Status Report as of 007/0000Z

1.0 OBSERVATIONS SCHEDULED AND ACCOMPLISHED:

    1.1 Completed Six Sets of FGS 8532 (White Dwarf and M-Stars in the 
Solar Neighborhood; Revealing Binarity)

        FGS-1 was used to conduct a high angular resolution survey with 
FGS1r to detect binarity among nearby M dwarfs and white dwarfs.   As 
reported in yesterday's report and HSTAR 7465, while the acquisition for 
the first iteration of this proposal succeeded, no astrometry was 
performed.  Otherwise, the observations completed with no further reported 
problems.

    1.2 Completed STIS/MA1 8510 (FUV MAMA Darks)

        The Space Telescope Imaging Spectrograph (MA1) was used to 
determine the health of the FUV MAMA detector by monitoring the background 
count rate.  The observations completed with no reported problems.

    1.3 Completed Two Sets of STIS/MA2 8509 (NUV MAMA Darks)

        The Space Telescope Imaging Spectrograph (MA2) was used to 
determine the health of the FUV MAMA detector by monitoring the background 
count rate.  The observations completed with no reported problems.

    1.4 Completed STIS/CCD 8507 (CCD Darks)

        The Space Telescope Imaging Spectrograph (CCD) was used to obtain 
weekly updates to the hot pixel list.   The proposal completed as planned.

    1.5 Completed Two Sets of STIS/CCD 8508 (CCD Bias Monitor C8)

        The Space Telescope Imaging Spectrograph (CCD) was used to obtain 
updates to the weekly superbiases.  The proposal was completed as planned.

    1.6 Completed WF/PC-2 8492 (UV Monitor for -88C Cooldown)

        The WF/PC-2 was used to conduct the UV monitor after the first 
cooldown to -88C. Throughput measurements are also made using UV filters 
and UV crossed with long-pass filters to determine red leak 
contribution.  -These are used to indicate any drop in throughput at Lyman 
alpha, which could be due to contamination in the pick-off mirror.  The 
proposal completed nominally.

2.0 FLIGHT OPERATIONS SUMMARY:

    2.1 Guide Star Acquisitions:
       Scheduled Acquisitions: 11
Successful: 11

  Scheduled Re-acquisitions: 0
Successful: 0

    2.2 FHST Updates:
Scheduled: 29
Successful: 29

    2.3 Operations Notes:

        The Servicing Mission Observatory Verification (SMOV) program is 
continuing.

        Using ROP SR-6 as a guide, there were four SSR-1 memory location dumps.

        The SSR pointer was set twice as directed by ROP SR-3.

        The SSA transmitter was turned on and off at 006/1453Z per ROP 
IC-2.  SSAT-2 was power cycled at 006/2046Z.

        The 486 was dumped, and the results were compared successfully, at 
006/2136Z.  ROP DF-06A was used.

        Using ROP NS-3, the NSSC-1 status buffer was dumped and reset at 
007/0105Z.

        The Vehicle Disturbance Test (VDT) procedure was again initiated at 
007/0940Z.  The results have been nominal.  The next iteration of this test 
will be conducted tomorrow.

3.0 SIGNIFICANT FORTHCOMING EVENTS:

        Continuation of SMOV and normal science observations and calibrations.
