SOT Shift Report 2007-12-18 L3072 Duration: 18 Dec 2007 07:00 EST - 18 Dec 2007 9:15 EST (Day 352) 18 Dec 2007 12:00 GMT - 18 Dec 2007 14:15 GMT SOT Lead: Bill Podgorski ======================================== Plan ---- Runing DEC1707A in radiation zone. Perform CAPs 1051 and 1050 to turn off EPHIN detector G HV and patch RADMON to recognize this.

The RADMON function was patched to recognize this change using an associated CAP 1050. All proceeded nominally.

Eng: - SOT/Radiation: - ACE protons are moderate (~2000) and still slowly rising. - Solar Activity Forecast: Solar activity is expected to be very low, although there continues to be a chance for an isolated C-class event. - Geophysical Activity Forecast: Geomagnetic activity is expected to be unsettled to active for the next three days (18-20 December), due to continued influence of the high speed stream.
