SOT shift report 2005-08-02 L2203 File created at 2005:214:12:44 UTC = 08:44 AM Aug-02-2005 EDT End 11:00:00 AM EDT SOT Lead: Ed Kellogg PLAN ---- OBSID None. We have safed the Science Instruments because of a radiation shutdown. We are beginning a restart plan for tomorrow. RADIATION SUMMARY ----------------- Solar soft proton flux is high, dropping rapidly (http://www.srl.caltech.edu/ACE/ASC/) Significant solar activity: The solar flare activity level was moderate. A total of 2 C and 1 M class events was recorded yesterday. (http://www.dxlc.com/solar/) CMEs reported for past two days: July 31 - August 1: No obvious partly or fully Earth directed CMEs were observed.

Next passes(yyyy:ddd:BOT-EOT)2005:214:2110-2210 2005:215:0345-0445 MP: We ran SCS 107 during obs 5954. We can stay at the current attitude until rad exit, but we need to maneuver to cool off and improve momentum. We will begin replan this morning. S/C: There was an issue with the first SCS 129. The CFC command load reject counter incremented by 1. We cleared and reloaded successfully on the second attempt. Of course this load was moot because of the radiation shutdown. GOT/IST: The TLM data to OPS was interrupted briefly by a COGS problem. COGS was recycled and data flow was restored. We have opened a DDTS entry to investigate this issue. DATA: - SOT: Goes X-ray flux - A long duration M class event at ~1400 UTC yesterday. A short duration C class event today at ~0730 UTC. MEETINGS -------- A radiation replan meeting occurred at 9:15 am. See below. Data ---- On colossus (/dsops/GOT/input), - Aug 1 23:27 2005_213_1609_214_0017_Dump_EM_62705.gz.

Radiation telecon: We plan to restart at rad exit 215:19:00. Ken Gage will plan to do a maneuver at the 215:02:45 DSS 24 pass for cooling and momentum management. ACIS may want to run a CTI at the 214:20:10 pass.
