Analysis of Solar Active Regions and Activity from 23/2100Z to 24/2100Z: Solar activity was very low. An active area beyond the east limb (N09) produced several B-class flares today. The largest of these was a B3 flare at 24/1012Z. The visible disk remains spotless. IB. Solar Activity Forecast: Solar activity is expected to be very low. There is a slight chance of an isolated C-class flare from the active area located beyond the east limb. IIA. Geophysical Activity Summary 23/2100Z to 24/2100Z: The geomagnetic field was quiet. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet to unsettled for the next three days (25-27 June). III.
