NOTES/ISSUES/PROBLEMS
---------------------
From the 9am status meeting:
3 Supports Completed in the last 24 hours (Total time: 6.3 hours)
2 SSR dumps
Loads good through: 2025:012:04:41:32
Radiation:
Solar activity is likely to be moderate with a chance for X-class flares on
day one (08 Jan) and likely to be moderate with a slight chance for an X-class
flare on days two and three (09 Jan, 10 Jan).
MP:
Jan1325 loads are in work.
ENG:
On the last night support, caution-high limit violated for
the 3TSMXCET thermistor due to attitude-based heating at
a high pitch angle (176 deg).
Tomorrow on the morning support, pre-approved CAPs for EIA
Sequencer-A self-test and associated diagnostic dumps.
GOT:
No issues.
