SOT shift report 2005-12-12 L2335 File created at 2005:346:13:52 UTC = 08:52 AM Dec-12-2005 EST End 11:00:00 AM EST SOT Lead: Ed Kellogg Today is the 35th anniversary of the launch of the first orbiting x-ray astronomy observatory, Uhuru, also known as Small Astronomy Satellite - A,(SAS-A), SAS-1, Explorer 42, and the X-ray Explorer. We've come a long way since then! PLAN ---- OBSID 07153, NGC 5253 2005:346:08:39, ACIS-S NONE - The Discrete X-ray Source Population in NGC~5253, our nearest post-starburst galaxy: Completing the starburst sequence. RADIATION SUMMARY ----------------- Solar soft proton flux is very low (http://www.srl.caltech.edu/ACE/ASC/) Significant solar activity: At midnight there were 3 spotted regions on the visible solar disk. The solar flare activity level was low. A single C class event was recorded yesterday. (http://www.dxlc.com/solar/).Very quiet. CMEs reported for past two days: December 9-11: No obvious partly or fully Earth directed CMEs were observed in incomplete imagery..

Notes from 9 am meeting ------------------------ OPS: Passes 9 Supports Completed (8 34 Meter, 1 26 Meter) from 343/1400 - 346/1400 Dump status Current Data loss None Last load segment ends 2005:350:03:50 CAPs, last 24h: None Next passes(yyyy:ddd:BOT-EOT)2005:346:2200-2300 MP: The DEC1905A load should be out for review within 24 hours. This one will cover two weeks over the holiday. S/C: EPHIN was hot Saturday: 105 deg. The new model predicted 104.9. The EPHIN rail is now at 20 V, 90.5 deg, so is recovering. On Friday we adjusted the GRETA yellow limit on EPHIN from 105 to 115 deg. On Saturday we had a couple of MUPS 2A dropouts. Spacecraft engineering would like to discontinue reporting them unless their nature changes. We are considering this option. GOT/IST: There was a power outage on Saturday at the OCC. The only irregularity was that the rhodes server should have stayed on, but it was inadvertently plugged in to house power instead of the UPS.
