Unlocking the Secrets of the Universe

Daily Report #5259

Period Covered:
07:00 pm December 6, 2010 - 06:59 pm December 7, 2010
(DOY 341/0000z - 341/2359z)

Flight Operations Summary

Significant Spacecraft Anomalies: (The following are preliminary reports
of potential non-nominal performance that will be investigated.)

12525 - GSAcq(1,2,1) at 341/18:52:21z and REAcq(1,2,1) at 341/20:27:45z both resulted in fine lock
back-up on FGS2 due to scan step limit exceeded on FGS1.
Observations possibly affected: STIS 72-77 Proposal ID#11737; WFC3 80 Proposal ID#12342; WFC3 81-85 
Proposal ID#12346; STIS 76 Proposal ID#12415.

12526 - During the REAcq(2,3,3)scheduled at 341/23:05:26z we received ESB message "a0e"
(FGS Sequential Attitude update failed because error was too large to correct) at 341/23:08:35z. The
REacq was successful.
