Shift L3641. Start at 191:12:00 GMT = 08:00am 10 Jul EDT End 10:00am 10 Jul SOT Lead DAS (Times will be given in GMT on day 191.) PLAN ---- Continue running load JUL0909B. Finish obsid 10929, an ACIS-I DDT observation of PSR J1622-49 to characterize the X-ray counterpart of a newly discovered neutron star. Then do obsid 9957, an ACIS-S observation of the globular cluster NGC 6342 as part of a survey of "core collapsed" globular clusters. Then do obsid 10411, an ACIS-I observation of Abell 2276 as part of a study of dying radio sources in clusters of galaxies. Then do obsid 10239, an ACIS-I observation of 4C 73.08 as part of a survey to complete Chandra observations of 3CRR radio sources at redshifts less than 0.1 to resolve their components. Then into perigee passage.

ACIS focal plane temperature -119.5 degC. EPH temp: 122.49 degF NOTES/ISSUES/PROBLEMS From the 9am status meeting: Five supports over the past day. DSS-27 was unable to support due to a microwave switch failure, comm switched to DSS-65. Subsequent comm with DSS-27 was successful. Three stored command sequences were uplinked, on-board loads good until 195:11:40. The JUL1009B loads were approved yesterday. These were redone to omit grating observations and carry through the next week. Several of the engineering thermal trending limits were hit as we are in a hot configuration, but still well below real yellow limits. Test case matrix for OTG move software (i.e., K_constants) patch is being reviewed by FOT/engineering. Expect to circulate today for a wider review early next week.
