Sept 14, 2005 Email ------------------- SCS-107 ran nominally at ~257:01:06 UT due to high radiation (E1300). The attitude is good until ~260:07:00 so no short-term action is required. Radiation is still rising and there was a large, fast, full-halo CME associated with the long-duration X-class flare earlier today. Setp 14, 2005 Telecom ---------------------- SCS 107 ran last night at 257:01:06 GMT, due to high E1300 rates. Those were caused by a series of 3 X-class flares. The SCS 107 run was nominal, and we can maintain our current position for several days from a thermal and momentum point of view. At the recent pass which ended at 1215 GMT (8:15 am EDT) E1300 was just under half the trigger level and P4GM just above 1/3 trigger level. GOES 4-9 proton rates are level or slowly increasing. ACE 115-195 keV protons are at about 1100 and steady, but the rates for channels 310 keV and higher are increasing. We have just entered the perigee passage, and would have emerged and resumed observing at 258:03:33 GMT (~11:33pm EDT tonight). HOWEVER, we expect the CME associated with this event to hit tomorrow and increase the soft proton flux, and give high ephin rates. Typically we can expect to be off the air for 48 hours following the SCS 107 trip. We decided to target a restart following the comm pass starting at 258:2040 GMT, i.e., 4:40pm EDT tomorrow.
