SOT shift report 2004-10-20 L1917 Written at 2004:294:12:22 UTC = 08:22 AM Oct-20-2004 EDT End 11:00:00 AM EDT SOT Lead: Ed Kellogg PLAN ---- OBSID 06145, Abell 426 2004:293:22:42:28.690 86.0 ACIS-S NONE - Continuing exposure to build up a megasecond image of the core of the Perseus Cluster. 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 low. A total of 2 C class events were recorded yesterday. (http://www.dxlc.com/solar/) CMEs reported for past two days: October 18-20: No obviously Earth directed CMEs observed.

It was delayed yesterday because of database access problems. We expect to release products today for review tomorrow. S/C: We expect more prop line violations because of our current attitude, with the tail pointing at the Sun. We are investigating these violations. We see that the location of the sensors relative to the thermostat and the changing thermal gradients in the spacecraft could be the cause. There are likely to be more violations this week because we'll be at pitch angle of 175 degrees. GOT/IST: DATA: SOT: Goes X-ray flux - A C class event at ~0230 UTC and an M class at ~1130 today, both short duration.
