Analysis of Solar Active Regions and Activity from 09/2100Z to 10/2100Z: Solar activity was low. Todays activity consisted of a C3 x-ray event at 1057Z and a B1 x-ray event at 1452Z. Both events originated from newly numbered Region 1034 (N20E59), a small Bxo Beta group. IB. Solar Activity Forecast: Solar activity is expected to be very low to low. There is a chance for an isolated C-class event from Region 1034 during the next three days (11-13 December). IIA. Geophysical Activity Summary 09/2100Z to 10/2100Z: The geomagnetic field has been quiet. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet for the next three days (11-13 December). III.
