NOTES/ISSUES/PROBLEMS
---------------------
From the 9am status meeting:
2 Supports Completed in the last 24 hours (Total time: 4.6 hours)
2 SSR dumps
Radiation:
A moderate geomagnetic storm is now predicted for the weekend due to the edge
of the CME launched following the long duration M8.2 flare from Thursday.
We will watch the ACE rates over the weekend for any enhancements and provide
updates if neccessary.
Solar activity is expected to be moderate with a chance for X-class flares on
days one, two, and three (02 Aug, 03 Aug, 04 Aug).
MP:
Aug0524A loads are approvable. A medium response TOO arrived and was
approved yesterday and will be incorporated today into the B version
of these loads.
ENG:
During the late pass last night, there was a Caution-High limit violation
for one of the MUPS fuel tank temperatures (PMTANK3T). The temperature was
just over the limit and appeared to be due to attitude-based heating allowed
from relaxed MUPS valve temperature constraints. Will explore adjustments
to the tank temperature limits to accommodate the new operating levels.
GOT:
No issues.
