NOTES/ISSUES/PROBLEMS
---------------------
From the 9am status meeting:
3 Supports completed in the last 24 hours (total time: 6.9 hours)
3 SSR dumps
Loads good through: 2017:112:20:35:01
1 CAP:
1416, 109/1230z, PR397 RadMon EPHIN Count Threshold Patch,
applied to both OBCs to update the EPHIN channels E150 and
E1300 average count thresholds to prevent fixed overflow
errors. Ran nominally.
Radiation:
Solar activity is expected to be very low with a chance for
a C-class flares and a slight chance for an M-class flare on
days one, two, and three (19 Apr, 20 Apr, 21 Apr).
MP:
Apr2417A load review today at 2pm.
May0117 loads remain in work.
Eng:
As a follow-up to the software patch we will run
checksum memory dumps during the next passes.
GOT:
No issues.
