SOT shift report 2003-08-05 L1475 Written at 2003:217:13:28 UTC = 09:28 am Aug-05-2003 EDT End 11:00:00 AM EDT SOT Lead: Ed Kellogg PLAN ---- OBSID 03918, H2777 2003:216:22:38, ACIS-S NONE - LOCALIZATION OF "OPTICALLY DARK" Gamma Ray Bursts WITH SLOW TOO OBSERVATIONS. RADIATION SUMMARY ----------------- Solar soft proton flux is Low. (http://www.srl.caltech.edu/ACE/ASC/) Significant solar activity: Solar flare activity was low. There was no significant activity Aug 3-4. One C class event was recorded today at ~09:00 UTC and a short M class event at ~13:00 UTC. CMEs reported for past two days: A full halo CME was observed at ~05:00 UTC on 3 Aug. This might be directed 180 degrees away from earth, since there was no significant x-ray event associated. If it is coming our way, it might affect Chandra today.

S/C: Yesterday's eclipse was nominal. ASVT testing of the safe mode recovery sim was rescheduled to Thursday. We reviewed the CAP to clear the EPS glitch counter and decided to modify it and review it again this morning. It was approved this morning for upload right away. GOT/IST: - DATA: SOT: The EPHIN workstation monitor is not working properly. An entry was made into ClearDDTS.
