NOTES/ISSUES/PROBLEMS
---------------------
From the 9am status meeting:
8 Supports Completed over the weekend (Total time: 18.6 hours)
7 SSR dumps
Loads good through: 2022:281:17:20:14.000
Radiation:
3 M and 1 X class flare over the weekend, ACE rates are elevated.
Solar activity is likely to be moderate with a chance for X-class flares on
days one, two, and three (03 Oct, 04 Oct, 05 Oct).
MP:
No issues.
ENG:
Eclipse was nominal. There was an unexpected OBC-B error log entry,
The error was logged about 50 minutes before perigee. The suspicion
is that the error was caused by a SEU in one of the IU-A memory
buffers (rather than something on the OBC-B side of the interface).
GOT:
No issues.
