Shift L1476. Start at 218:12:00 GMT = 08:00am 06 Aug EDT End 11:00am 06 Aug SOT Lead DAS (Times will be given in GMT on day 218.) PLAN ---- Continue running load AUG0203A. Do obsid 3933, ACIS-S observation of NGC 5204 X-1, an ultraluminous X-ray source in a nearby galaxy. Then ACIS CTI measurements surrounding perigee passage.

On-board loads good until 221:01:40. Ran CAP 889 to dump and reset the EPS glitch counter. All values were as expected for the single spurious battery disconnect glitch. Working issues for the AUG1103 loads. Expect them out this morning for a telecon review at 2pm. Star selection working group cancelled for today.
