To:sot_shift from: Dan Schwartz date: 23 Nov 2010, 10:00 EDT Subject: SOT shift report 2010-11-23 L4142 -------- See http://asc.harvard.edu/acis/SOT_reports/sot-shift.html, or /proj/web-cxc/htdocs/acis/SOT_reports/Nov_23_2010_L4142.txt. Shift L4142. Start at 327:13:00 GMT = 08:00am 23 Nov EST End 10:00am 23 Nov SOT Lead DAS (Times will be given in GMT on day 327.) PLAN ---- Continue running load NOV2210A. Measure ACIS external cal source surrounding perigee passage. Upon egress from radiation belts do obsid 11539, an ACIS-S observation of the gravitationally lensed quasar Q2237+0305 to probe the accretion disk via microlensing by stars. Then do obsid 12886, continuing an ACIS-I observation of the merging cluster of galaxies Abell 2034, to distinguish between a cold front and a merger shock, and to study features of the shock. 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 331:13:55. CAP 1168 ran successfully to uplink patch request 281, which increased the temperature limits on the telescope thermal health check (a check for switching the thermal control from side A to side B, which is undesireable unless there is an actual failure on side A). NOV2910A products were out yesterday for review today at 2pm. (The SOSA working group scheduled for 2pm will start after the review is complete.) Sun is very quiet. ACE protons at background level.
