NOTES/ISSUES/PROBLEMS
---------------------
From the 9am status meeting:
3 Supports Completed in the last 24 hours (Total time: 6.9 hours)
3 SSR dumps
Radiation:
The expected CME passage was observed yesterday evening when the ACE P3
rates briefly reached ~45,000 and then dropped significantly to the
current level of ~4,000. There was no mission impact. We will continue
watching the rates for any additional enhancements.
Solar activity is expected to be moderate with a chance for X-class
flares on days one, two, and three (30 Jul, 31 Jul, 01 Aug).
MP:
Aug0524 loads are in work.
ENG:
Pre-approved CAP on the late support tonight to swap
prime SSR to backup.
GOT:
No issues.
