SOT Shift Report 2004-09-14 L1881 Duration: 14 Sep 2004 08:30 EDT - 14 Sep 2004 10:00 EDT 14 Sep 2004 12:30 GMT - 14 Sep 2004 14:00 GMT SOT Lead: Tom Aldcroft ======================================== Plan ---- No load running. Events ------ No comm this shift Notes/Issues/Problems --------------------- - SCS107 ran at 257:2138. Both P4GM and E1300 channels exceeded the RADMON limits at about the same time - Nominal replan at this time is plan B: pick up loads 50 ksec after radiation exit to include XRF040825 and the Ricker TOO. A maneuver-only load is under consideration because of the impending momentum limit violation at 259:2300. - ACIS is planning a CAP to do a long CTI measurement on the tail end of this perigee until science restarts - GOES hard proton rates are currently at the value equivalent to the P4GM RADMON trip rate and declining slowly - ACE rates are near the SOT alert values and declining slowly as well: ACE 130-214 keV proton fluences (p/cm2-sr-MeV) and Costello predicted activity index OBSERVED SOT alert ------------ ------------- 2-hour Fluence: 3.2e+08 3.6E+8 Kp: 3.3 6.0 - Solar Activity Forecast: Solar activity is expected to be low to moderate. Isolated M-class flares from Region 672 are possible. - Geophysical Activity Forecast: The geomagnetic field is expected to be at minor to major storming levels on 14 September, due to the effects of a CME arrival. Conditions should subside to quiet to active levels on 15 and 16 of September, although isolated minor storm conditions are possible on those days from the effects of a geoeffective coronal hole.
