NOTES/ISSUES/PROBLEMS
---------------------
From the 9am status meeting:
2 Supports Completed in the last 24 hours (Total time: 4.6 hours)
2 SSR dumps
Loads good through: 2023:242:23:50:02
Radiation:
Solar activity is expected to be low with a slight chance for an M-class flare
on days one, two, and three (25 Aug, 26 Aug, 27 Aug).
MP:
Aug2823A loads were approved yesterday.
ENG:
PCM3 temperatures reached their caution high limit on backorbit data.
Our perigee altitude is still very low, and because of this a few ACIS
low limits were triggered. We will continue to monitor these.
GOT:
No issues.
