NOTES/ISSUES/PROBLEMS
---------------------
From the 9am status meeting:
8 Supports Completed over the weekend (Total time: 18.4 hours)
8 SSR dumps
Loads good through: 2023:106:23:41:40
Radiation:
Solar activity is expected to be low with a chance for M-class flares on days
one, two, and three (10 Apr, 11 Apr, 12 Apr).
MP:
The first set of loads incuding HRC is on-board.
Apr1723 loads are in work.
ENG:
Over the weekend, the main load bus voltage (ELBV) reached levels just
below the present Caution-Low limit. This was associated with the solar
array temperature spikes seen due to Earth heating as the perigee altitude
gets lower. This is expected performance, and will lead to an adjustment
to the Caution-Low limit.
GOT:
No issues.
