NOTES/ISSUES/PROBLEMS
---------------------
From the 9am status meeting:
7 Supports Completed over the weekend (Total time: 16.1 hours)
9 SSR dumps
Loads good through: 2024:049:07:35:17
CAPs:
- 593A, 041/0321z, Manual SCS-107 Activation to Safe the Science Instruments
due to high radiation environment.
Radiation:
Solar activity is likely to be moderate with a 20% chance for an X-class
flare on days one, two, and three (12 Feb, 13 Feb, 14 Feb). Last night an
M6.5-class flare was observed from active region 3576 in the western part
of the visible disk, and a large filament eruption was detected from the
far side of the disk, likely from the same region which produced the X3.3
flare on Friday. The GOES rates increased again this morning and the GOES
HRC proxies exceeded the limit (no mission impact: HRC observations are
planned in the next 24 hours). The ACE P3 rates have been settling down
over the last 12 hours. However, there is a shock passage predicted for
today and tomorrow (Feb 12-13), mainly due to the CMEs launched on Feb
10-11, which may cause an increase of the ACE P3 rates.
MP:
No issues.
ENG:
No issues.
GOT:
No issues.
