Soft proton flux was in the 50,000 to 60,000 range at the time of the telecon. We expect to see even more radiation later today/tomorrow as the effects of the full-halo CME at 020/0000 are felt. Therefore, we decided to manually run SCS107, which was done via CAP 943 at about 021:1151UT. We were observing M101 (obsid 5296) at the time of shutdown. Replan activities under way, see MP report below. Next radiation discussion will be at the 9am tomorrow. 3-day Solar-Geophysical Forecast issued Jan 20 at 22:00 UTC Solar Activity Forecast: Solar activity is expected to be low to moderate. Though in decay, Region 540 still maintains potential for isolated M-class flares. The remaining three spot groups on the visible disk have potential for C-class activity. Geophysical Activity Forecast: The geomagnetic field is expected to range from quiet to major storming over the next three days. Quiet to active periods are expected on 21 January. The full halo CME observed on LASCO imagery at 20/0006Z will likely impact the geomagnetic field early on 22 January. Active to major storm periods are possible. Unsettled to active conditions are expected on January 23 as the storm subsides.

This will be done today and uplinked during tonight's pass (022/0345), and executed shortly after uplink. * Plan A replan will pickup with GRB031203 (obsid 5298). Uplink will be during the 022/1855 pass (later tomorrow). If necessary, this observation could be shortened from the time now planned. This Plan A also includes necessary eclipse management. * If radiation levels preclude Plan A, Plan B will be a load to handle the next eclipse (after next perigee). S/C Engineering(Dan): - SCS107 ran nominally this morning. - Eclipse last night was nominal. - More ASVT testing was done yesterday, still checking out patches for CPE associated with MUPS testing. - Will run CAP 902 later on today to disable momentum unloading subfunction.
