Analysis of Solar Active Regions and Activity from 07/2100Z to 08/2100Z: Solar activity was low. Region 9335 (N09E01) produced a C1/Sf at 08/2030 UTC. This area has decayed somewhat since yesterday but contains some mixed polarity fields. Other disk regions have decayed a little or remain small and simple. Newly numbered Regions 9344 (N31E13) and 9345 (S20E19) emerged on the disk. IB. Solar Activity Forecast: Solar activity is expected to be very low to low. Region 9335 remains the most likely source of flares. IIA. Geophysical Activity Summary 07/2100Z to 08/2100Z: The geomagnetic field was quiet to unsettled. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet to unsettled. III. Event Probabilities 09 Feb-11 Feb Class M 10/10/10 Class X 01/01/01 Proton 01/01/01 PCAF green IV.
