SOT shift report 2002-12-17 L1244 Written at 2002:351:14:26 UTC = 09:26 am Dec-17-2002 EST End 11:00:00 AM EST SOT Lead: Ed Kellogg PLAN ---- OBSID 60918. We are at perigee. We are doing CAL-ER 2002:351:06:32, then CAL-ER 2002:351:15:35. RADIATION SUMMARY ----------------- Solar soft proton flux is Low. (http://www.srl.caltech.edu/ACE/ASC/) Significant solar activity yesterday: Solar flare activity was moderate. A total of 12 C and 3 M class flares were recorded during the day(http://www.dxlc.com/solar/). CMEs reported for past two days: December 14-15: No obviously geoeffective CMEs noted. December 16: A weak CME was associated with an M2.5 flare. Most of the CME was visible off the northeast limb and the north pole in LASCO C2 images, but there may have been some faint (and geoeffective) extensions as well. A larger CME was in progress off the southwest limb most of the day. (http://www.dxlc.com/solar/).

S/C: The PCAD group met yesterday and decided to recommend turning off the aberration correction (for spacecraft orbital motion) for the rest of the mission. This will improve our ability to locate targets on the detector. GOT/IST: - DATA: hea-www server was down starting at 7:00 this morning, causing difficulty processing the quick look images. SOT: GOES x-ray flux: No significant activity today. Yesterday's x-ray events do not appear to be geoeffective. MEETINGS -------- Load review.
