Shift L4053. Start at 239:12:00 GMT = 08:00am 27 Aug EDT End 10:00am 27 Aug SOT Lead DAS (Times will be given in GMT on day 239.) PLAN ---- Continue running load AUG2310A. Finish obsid 11235, an ACIS-S observation of FERMI-LAT PSR J2021+4026 to identify the 5th brightest source in the gamma ray sky: no counterparts exist to this pulsating source. Then measure acis-cti surrounding the perigee passage. NOTES/ISSUES/PROBLEMS --------------------- From the 9am status meeting: Three supports in the past day, no issues. One stored command sequence uplinked, on-board loads good until 243:12:50. The AUG3010A products were approved yesterday, and the first segment was uplinked. This afternoon we will run the pre-approved CAP to update the on-board ephemeris. Sun is quiet.
