Shift L2927. Start at 208:12:00 GMT = 08:00am 27 Jul EDT End 10:00am 27 Jul SOT Lead DAS (Times will be given in GMT on day 208.) PLAN ---- Continue running load JUL2307B. Finish obsid 7641, an ACIS-I observation of the pulsar wind nebula 3EG J1826-1302, which is possibly associated with a variable gamma-ray source. Then do obsid 7628, an ACIS-I observation of the "Rotating RAdio Transient" J1826-14, to obtain a precise location. Then 7693 and 7705, observations of the Abell clusters 2244 and 222 as part of an ACIS-I GTO program to search for X-ray outbursts in rich clusters. Then obsid 7411, an ACIS-S/HETG GTO observation of the Orion Trapezium Cluster to study these very young stars as a function of their magnetic and accretion properties.
