To:sot_shift from: Dan Schwartz date: 14 Oct 09, 10:00 EDT Subject: SOT shift report 2009-10-14 L3735 -------- See http://asc.harvard.edu/acis/SOT_reports/sot-shift.html, or /proj/web-cxc/htdocs/acis/SOT_reports/Oct_14_2009_L3735.txt. Shift L3735. Start at 287:12:00 GMT = 08:00am 14 Oct EDT End 10:00am 14 Oct SOT Lead DAS (Times will be given in GMT on day 287.) PLAN ---- Continue running load OCT1209B. Do obsid 9922, an ACIS-S observation of the classical T Tauri star HN Tau, to search for microjets and test the conjecture that jets may be common as part of the star formation process. Then do ACIS external cal source (aka "cti") measurements surrounding perigee passage. NOTES/ISSUES/PROBLEMS --------------------- From the 9am status meeting: Three supports over the past day. No issues. One stored command segment uplinked, on-board loads good until 291:00:04. OCT1909 product release is delayed while a waiver is negotiated to avoid turning off an ACIS chip. The issue is due to the inaccuracy of the FOT thermal model -- the more accurate SOT model predicts no temperature violation for ACIS PSMC.
