SOT shift report 2002-11-27 L1224 Written at 2002:331:15:49 UTC = 10:49 am Nov-27-2002 EST End 11:00:00 AM EST SOT Lead: Ed Kellogg PLAN ---- OBSID 4408. We did an SCS 107 shutdown last night because of very intense low energy proton fluxes from a CME on 24 Nov. From this morning's 9:30 am telecon: since the ACE levels are now 35500, and dropped by 9.6% in the past hour, we project that by the time we uplink the new load ~12 hours from now, the rates will be at ~12000. If so, this will give us an expected average flux for obs 3217 of ~8000, for an additional dose of ~ 0.3e+09 in the first 40 ks observation. We then shut down and go into the radiation zone. This is an acceptable scenario, so we will proceed with that plan. We need to watch the SOHO LASCO images to see what effect today's x-ray event will have on further observations Friday and Saturday. RADIATION SUMMARY ----------------- Solar soft proton flux is Very high, but dropping. Significant solar activity: There was a rather intense long duration x-ray event at ~02:30 UTC today, 27 Nov. It is too early to know if there was an associated CME. This event may cause trouble on Thursday or Friday. CMEs reported for past two days: November 25 & 26: No obviously geoeffective CMEs were observed.

Next passes 0245, 0700 MP: We had to safe the instruments last night because of high radiation. We are replanning now, with products due out later this morning, a review this afternoon at ~2 pm, and uplink of the new load at 28 Nov.2002 02:45 UTC. S/C - GOT/IST: The telem2 AMASS databaseis giving retrieval errors. We will regenerate it. DATA:Two quicklooks. SOT: GOES x-ray flux: Quiet on 25-26 Nov. There was a rather intense long duration event at ~02:30 UTC today, 27 Nov, that may cause trouble in a day or so.
