NOTES/ISSUES/PROBLEMS
---------------------
From the 9am status meeting:
8 Supports Completed over the weekend (Total time: 18.3 hours)
8 SSR dumps
Loads good through: 2023:114:02:28:59
Radiation:
Solar activity is expected to be low with a 50% chance for M-class flares
and a slight chance for an X-class flare on days one, two, and three
(17 Apr, 18 Apr, 19 Apr).
MP:
No issues.
ENG:
At the end of eclipse over the weekend we had a battery disconnect
circuit glitch, which we see sometimes. A pre-approved CAP will be
