Observing '3C 388' with ACIS-I/NONE. Radiation levels started to rise steeply at about 009/0200UT, probably due to this morning's M3 flare. Currently at 55,000 (7:45am EST) and still rising. Radiation telecon held at 8:20EST. Decided to run SCS-107 since rates were very high and rising. Radiation Discussion Summary 9:15am, 1/9/2004: SCS-107 commanded at 009/1345UT due to high radiation. Maneuver needed before tomorrow morning to avoid earth violation at 010/0712 Uplink maneuver load during either 009/2310 or 010/0250 passes. Replan options: Plan A resumes at about 010/2000UT, picking up with obs 4745 Plan B resumes before 011/1200, picking up obs 4668. Radiation telecon today(Friday) Jan 9 at 4pm EST on 405-244-5060 PIN 1165# 3-day Solar-Geophysical Forecast issued Jan 8 at 22:00 UTC Solar Activity Forecast: Solar activity is expected to be moderate for 09-11 January with Regions 536 and 537 being the most likely source for activity. There continues to be a slight chance for a major flare or proton producing flare from either of these regions during the 09-11 January forecast period. Geophysical Activity Forecast: The geomagnetic field is expected to be generally unsettled for 09-11 January with a slight chance for isolated active periods.

Decided to accept it since we can't do much about it and it will not be harmful. - Disucssions of eclipse plan and heater anomaly at FDB yesterday. - Heater anomaly discussion re-focussed efforts of getting a fault tree put together. Will have it in about a week. This is based on the fact that the heater being stuck on does not present any performance or safety risks. SOT(Bill): - See above notes on radiation.
