SOT shift report 2006-07-18 L2553 File created at 2006:199:12:54 UTC = 08:54 AM Jul-18-2006 EDT End 11:00:00 AM EDT SOT Lead: Ed Kellogg PLAN ---- OBSID CAL-ER (58872) 2006:199:09:43, then CAL-ER (58871) 2006:199:13:46 RADIATION SUMMARY ----------------- Solar soft proton flux is moderately high (http://www.srl.caltech.edu/ACE/ASC/) Significant solar activity: The solar flare activity level was very low. No C class events were recorded yesterday. There is a complex spot that could emit C flares. (http://www.dxlc.com/solar/). GOES x-ray flux: Very quiet. CMEs reported for past two days: July 15-17: No partly or fully Earth directed CMEs were detected in LASCO imagery.

S/C: We had the last of the eclipses of this season yesterday, with nominal results, subject to ongoing analysis of the data. We will execute the preapproved CAP29 to return Chandra to its non-eclipse state. GOT/IST: There will be welding activity near the conference room today, with accompanying odors. DATA: A dump yesterday had corrupted data. We requested a retransmission, which solved the problem - it was a ground issue.
