Shift L3267. Start at 183:13:00 GMT = 08:00am 01 Jul EDT End 10:00am 01 Jul SOT Lead DAS (Times will be given in GMT on day 183.) PLAN ---- Continue running load JUN3008C. Pass through perigee and measure ACIS CTI on egress. Then do obsid 9144, an ACIS-S/HETG observation of SN1987A to continue monitoring its expansion and brightness changes. Then do obsid's 9706 and 9705, ACIS-S/HETG and ACIS-S/LETG calibration observations of PKS2155-304, to monitor the contamination build-up on the ACIS filter, and for cross calibration with XMM and other satellites.

EPH temp: 93.79 degF EPH 27V: 26.84 NOTES/ISSUES/PROBLEMS From the 9am status meeting: Three supports over the past day. No issues. One stored command sequence was uplinked, on-board loads good until 187:07:57. Eighth eclipse of the season took place earlier this morning, real time telemetry indicates it was nominal. The pre-approved monthly sequencer self-test CAP will be run today. JUL0708 loads still in work, out in a day or two. DSops has received telemetry for obsid 57728, which is in the DOT but apparently not in the SOE and not in the archive. (Subsequent discussion after the 9am status indicated that this is a significant concern, and that the SOE/archive issue must be addressed.)
