Analysis of Solar Active Regions and Activity from 13/2100Z to 14/2100Z: Solar activity has been very low. Region 609 (S04E10) produced several low B-class flares during the past 24 hours. The region continues to show slight growth in white light area and sunspot count. IB. Solar Activity Forecast: Solar activity is expected to be very low to low. Region 609 has the potential to produce C-class events with a chance for an isolated M-class flare. IIA. Geophysical Activity Summary 13/2100Z to 14/2100Z: The geomagnetic field has been at quiet to unsettled conditions. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet to unsettled with isolated active periods. III.
