SOT shift report 2003-11-05 L1567 Written at 2003:309:15:09 UTC = 10:09 AM Nov-05-2003 EST End 11:00:00 AM EST SOT Lead: Ed Kellogg PLAN ---- Waiting to see what happens with high radiation levels. OBSID (none; no load) RADIATION SUMMARY ----------------- Solar soft proton flux is Very high. (http://www.srl.caltech.edu/ACE/ASC/) Significant solar activity: Solar flare activity was very high. A total of 10 C, 4 M and 1 X class events was recorded yesterday.(http://www.dxlc.com/solar/) CMEs reported for past two days: November 3: No partially or fully Earth directed CMEs observed. November 4: A fast, large, full halo CME was observed in LASCO C2 images beginning at 12:04 UTC. With no obvious frontside source this CME is likely to have originated near the center of the backside4. A huge and very fast full halo CME was observed after the super flare in region 10486 at 19:53 UTC. The speed of this CME has been estimated at nearly 2400 km/sec. While the core of the CME will not reach the Earth, the slower flank part could impact Earth early on November 6. Estimated arrival window: 23:00 UTC 05 Nov. to 15:00 UTC 06 Nov.

This would be for upload at 6:50 am tomorrow. We are also watching the momentum state. We may be OK even through plan C. S/C: - GOT/IST: We are ready to promote OFLS 3.9.4 to ops, pending a decision to go ahead. At this morning's meeting, it was decided no to go ahead right now. DATA:- SOT: It was decided not to go ahead with the ACIS bakeout in December. The next opportunity will be in April.
