To:sot_shift from: Dan Schwartz date: 01 Feb 10, 10:00 EST Subject: SOT shift report 2010-02-01 L3847 -------- See http://asc.harvard.edu/acis/SOT_reports/sot-shift.html, or /proj/web-cxc/htdocs/acis/SOT_reports/Feb_01_2010_L3847.txt. Shift L3847. Start at 032:13:00 GMT = 08:00am 01 Feb EST End 10:00am 01 Feb SOT Lead DAS (Times will be given in GMT on day 032.) PLAN ---- Continue running load FEB0110B. Finish obsid 10944, an ACIS-I observation of the Cyg OB2 starburst region, to study molecular cloud collapse, massive star formation and protoplanetary disk evolution. Then do obsid 10945, continuing the Cyg OB2 study. Then do obsid 11960, an ACIS-I LETG calibration observaton of the BL Lac object Mkn 421 to measure contamination on the ACIS-I filter. NOTES/ISSUES/PROBLEMS --------------------- From the 9am status meeting: Nine supports over the weekend, no issues. Three stored command sequences uplinked, on-board loads good until 035:12:30. FEB0810 products expected out tomorrow, (possibly late tonight). Loss of real-time feeds to ACIS and MTA occurred around midnight Saturday. CXC-DSops reported this was due to "scrambled" data which killed the acorn process. Further investigation is pending. At the IST tagup it was reported that fix of 3 problems for the OFLS 11.7.5 build also apparently fixed 2 other problems. FOT/MP will be responsible for the test plan to verify this.
