Shift L3805. Start at 355:13:00 GMT = 08:00am 21 Dec EST End 10:00am 21 Dec SOT Lead DAS (Times will be given in GMT on day 355.) PLAN ---- Continue running load DEC2109B. Do obsid 11992, an ACIS-S/HETG observation of Eta Carina to study mass loss via line profiles, at various phases of the X-ray minima. Then do obsid 12061, an HRC-S/LETG observation of RX J0806.3+1527 to follow up a previous detection of line emission to constrain the history of this degenerate binary system via element identifications and abundances. Then do obsid 11017, another part of the Eta Carina observation. NOTES/ISSUES/PROBLEMS --------------------- From the 9am status meeting: Nine supports over the weekend. No issues, Two stored command sequences uplinked, on-board loads good until 360:03:45. DEC2809 products (the two week load) out last Friday, for review today at 2pm. Late Saturday one of the fine sun sensor brackets toggled its yellow high temperature limit for 8 to 10 minutes. Associated with the pointing direction and season, not a concern. Sun is very quiet, all proton indicators at background level. From the OCC tagup: There were two building evacuations, Friday and Sunday, due to a springler head low pressure and a leak. These occured in the new portion of the building. No damage resulted. There were short (< 5 seconds) dropouts of the T1 line on Sunday. Likely due to weather.
