Shift L9230.
Start at 302:13:00 GMT
PLAN
----
Vehicle loads.
SCS107 to high radiation.
Return-to-science planned for the 2024:304:01:15:00 DSS-24 pass.
NOTES/ISSUES/PROBLEMS
---------------------
From the 9am status meeting:
7 Supports Completed over the weekend (Total time: 16 hours)
8 SSR dumps
Loads good through: 2024:306:12:25:01
CAP's:
- 750AG, 301/0254z, Low Rate Dump of the On-line OBC Checksummed Memory (XSUM_1)
- 893B, 301/1715z | DISA SCS 29
- 1230P, 301/1716z | Manual OBSID Change, Set New OBSID (Post SCS 107 Run) 65519
- 750AH, 301/2246z | Low Rate Dump of the On-line OBC Checksummed Memory (XSUM_2)
- 750 AI, 301/2306z | Low Rate Dump of the On-line OBC Checksummed Memory (XSUM_3)
Radiation:
The ACE P3 and HRX GOES proxy rates are high due to a combined effect of two CMEs
which passed Earth over the weekend. The second CME arrived before midnight night
and since then the ACE P3 rates have been slowly decreasing (currently at ~100,000).
The HRC GOES proxy rate has been topping over the last 24 hours and it is currently
at ~150,000, and expected to start decaying as well. No other CMEs are expected in
the next 24 hours. Solar activity is expected to be moderate with a 30% chance for
X-class flares on days one, two, and three (28 Oct, 29 Oct, 30 Oct).
MP:
Return-to-science loads are in work.
ENG:
SCS107 run nomoinally. MUPS1 valve caution high temperature violation
in backorbit data due to attitude heating. The violation limit is currently
at the level of the planning limit and it will be adjusted.
GOT:
No issues.
