Lingering flare activity from Region 656 is still possible for another day. Region 661 is capable of producing isolated M-class flares. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet to unsettled for the next three days, with isolated active conditions possible on 20 August.
