Analysis of Solar Active Regions and Activity from 21/2100Z to 22/2100Z: Solar activity was very low. The visible disk remains spotless. IB. Solar Activity Forecast: Solar activity is expected to be very low. IIA. Geophysical Activity Summary 21/2100Z to 22/2100Z: The geomagnetic field has ranged from quiet to active due to a recurrent coronal hole high speed stream. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to range from quiet to unsettled for the forecast period, 23 - 25 June. Isolated active periods are possible. III.
