Shift L2995. Start at 276:12:00 GMT = 08:00am 03 Oct EDT End 10:00am 03 Oct SOT Lead DAS (Times will be given in GMT on day 276.) PLAN ---- Continue running load OCT0107A. Finish obsid 9719, an ACIS-S ToO to follow up a tidal disruption event discovered by GALEX. Then do obsid 8248, an ACIS-S observation of the AGN SDSS J014116-092420, as part of a survey to cross-calibrate [OIII], X-ray, and radio luminosities as accretion rate indicators. Then do obsid 9718, part of the ACIS-I DDT program to extend the exposure on the Chandra deep field-South. Also, run CAP 1040 to dump the IU-A eeprom contents.

EPH temp: 101.13 degF EPH 27V: 13.05 NOTES/ISSUES/PROBLEMS From the 9am status meeting: Three supports over the past day. A problem last night losing voice and command/TM connection with JPL, due to possible T1 problem. SSR dump had been completed, the problem cleared and the comm was extended 12 minutes to get a state of health check. DSS-27 has recently not been able to get the final transmitter turn-off commands to the satellite. They eventually clear the system and send the commands. One segment of OCT0107A was uplinked, on-board loads good until 279:21:15. OCT0807A products out yesterday, for a load review at 2pm today. CAP 1040 to dump the IU-A eeprom contents was successful. The contents were checked and are identical to the contents at launch. The Monthly EIA self-test CAP is planned to be run this afternoon. ACE proton rate data just returned as of 13:05 today. The 115-195 keV protons are at the background counting rate, and solar activity is extremely low.
