SOT shift report 2006-08-14 L2580 File created at 2006:226:12:35 UTC = 08:35 AM Aug-14-2006 EDT End 11:00:00 AM EDT SOT Lead: Ed Kellogg August 12, 1999 Cambridge, MA :: At 2:00 p.m. EDT today the Chandra X-ray Observatory received a command from the Chandra Control Center in Cambridge, MA, 84,000 miles away. A pyrotechnic charge equivalent to an M-80 firecracker exploded, sending a chisel through a bolt and a powerful spring swung open the 120-pound 9-foot diameter door protecting the delicate mirrors of the observatory. Chandra wobbled slightly, then settled down. The expectant Chandra team cheered and congratulated one another. Cosmic X-rays could shine onto the mirrors for the first time. - http://chandra.harvard.edu/chronicle/080999/light.html PLAN ---- OBSID 0697, CLASS B2108+213 2006:226:07:46, ACIS-S NONE - Dark and Luminous Matter in the B2108+213 Group. RADIATION SUMMARY ----------------- Solar soft proton flux is very low (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. (http://www.dxlc.com/solar/). GOES x-ray flux: One short duration minor B class event at 0900 UTC today.. CMEs reported for past two days: August 11-13: No partly or fully Earth directed CMEs were detected in LASCO imagery.

S/C: There was a limit violation on ACIS DEA. It was not a TLM dropout. We are investigating. GOT/IST: There was a problem with TLM1 preventing us from receiving NRT data. We rebooted and it's OK now. We are checking into the cause. We believe it was a memory leak. DATA: We missed GS1826-238, the target on obsids 6647 & 6648. We are investigating the cause of the error, and considering changes to prevent a recurrence. SOT: The snapshot web page is not updating correctly. The file in /pool14/chandra is incomplete.
