NOTES/ISSUES/PROBLEMS
---------------------
From the 9am status meeting:
2 Supports Completed in the last 24 hours (Total time: 4.5 hours)
5 SSR dumps
Loads good through: 2025:103:04:55:44
Radiation:
Solar activity is expected to be low with a chance for M-class flares on days
one, two, and three (09 Apr, 10 Apr, 11 Apr).
MP:
Apr1424 loads are in work.
ENG:
A warning-high limit for SSR-2 converter A, it will be investigated,
most likely a single-event upset seen before.
GOT:
No issues.
