Shift L2239. Start at 250:13:00 GMT = 08:00am 07 Sep EDT End 10:30am 07 Sep SOT Lead DAS (Times will be given in GMT on day 250.) PLAN ---- Continue running load SEP0505C. Finish obsid 6252, an ACIS-I observation of Cyg A to study the interaction of the radio source with the cluster. Then do obsid 5760, an ACIS-I observation of the high redshift ROSAT cluster of galaxies cl0216-1747, to measure the dark energy equation of state via evolution of the cluster mass function with redshift.

ACIS temperature -118.7 NOTES/ISSUES/PROBLEMS From the 9am status meeting: Two supports over the past day, one currently in call-up. No issues. SEP1205A products released yesterday, but recalled due to an OR ingestion problem. Problem is corrected, and SEP1205B products expected out this morning for a review at 2pm. ACE low energy proton rates are low, but low energy electrons are gradually rising over the past day following a long M-class flare. Active region 798 has rotated into view, so we may need to watch for solar protons over the next couple of days.
