To:sot_shift from: Dan Schwartz date: 11 Mar 2011, 10:00 EDT Subject: SOT shift report 2011-03-11 L4250 -------- See http://asc.harvard.edu/acis/SOT_reports/sot-shift.html, or /proj/web-cxc-dmz/htdocs/acis/SOT_reports/Mar_11_2011_L4250.txt (NOTE NEW LOCATION FOR THE REPORTS DIRECTORY AS OF DEC 2010) Shift L4250. Start at 070:13:00 GMT = 08:00am 11 Mar EST End 10:00am 11 Mar SOT Lead DAS (Times will be given in GMT on day 070.) PLAN ---- Continue running load MAR0611B. Finish the sequence of calibration observations of A1795 to monitor the contamination build-up on ACIS-I. Then go through perigee passage. NOTES/ISSUES/PROBLEMS --------------------- From the 9am status meeting: Three supports over the past day. No issues. One stored command sequence uplinked, on-board loads good until 073:15:06. MAR1411B loads are out for full email review by noon today. Gyro 2 channel 1 has shown more current spikes above 150ma. ACE soft proton rates continue to decline slowly, and somewhat irregularly. A telecon was held last night when orbital fluence reached 1e+9 and concluded that current rates were low enough that we could continue until the RADMON shutdown late this afternoon. Brent noted that tomorrow's power outage could have an impact on a replan if there was a radiation shutdown. However the planned outage is short enough that we can probably work around it.
