NOTES/ISSUES/PROBLEMS
---------------------
From the 9am status meeting:
2 Supports Completed in the last 24 hours (Total time: 5.6 hours)
4 SSR dumps
Radiation:
Multiple mid to upper level M-flares have been observed in the past 24 hours.
A couple of CMEs were likely produced from active regions near the west limb
and they should be directed mostly away from Earth.
Solar activity is expected to be moderate with a chance for X-class flares on
days one, two, and three (01 Aug, 02 Aug, 03 Aug).
MP:
Aug0524A load review today by 5pm.
ENG:
Investigation showed that a telemetry corruption event while
turning on an SSR, like the event reported yesterday, happened
before back in 2001. It was well documented and recognized as
benign. Procedures will be updated to recognize that this may
happen each time an SSR is turned on.
GOT:
No issues.
