Shift L1510. Start at 252:12:00 GMT = 08:00am 09 Sep EDT End 12:00 noon 09 Sep SOT Lead DAS (Times will be given in GMT on day 252.) PLAN ---- Continue running load SEP0803A. Finish obsid 3568, an ACIS-S/HETG observation of the bright HEAO A-3 BL Lac object H 1426+428, to search for the absorption by warm intergalactic gas. Then do ACIS-S obsids 4072, 4048, 4158, of the AGN's PSS 1646+5514, 2MASS153628+614642, and 7C 1745+6227, respectively.

Status is essentially unchanged. Descending through 1227221 km. ACIS focal plane temperature -119.7. NOTES/ISSUES/PROBLEMS New HRC racks are installed. From the 9am status meeting: Two 26m supports in the past day, no problems. On-board loads good until 255:07:15. The test support scheduled for 253:0405 has been deleted, due to hardware problems at the ground station. SEP1503A products were circulated yesterday for comments. Load review at 2pm EDT today. One more historic MUPS anomaly was found by searching during maneuvers. This uses new software capability to analyze maneuvers.
