Analysis of Solar Active Regions and Activity from 20/2100Z to 21/2100Z: Solar activity was very low. The visible disk is spotless. IB. Solar Activity Forecast: Solar activity is expected to be very low. IIA. Geophysical Activity Summary 20/2100Z to 21/2100Z: The geomagnetic field has been quiet to unsettled due to recurrent coronal hole high speed stream rotating into a geoeffective position. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet to active for the forecast period, 22 - 24 June. III.
