Analysis of Solar Active Regions and Activity from 22/2100Z to 23/2100Z: 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 22/2100Z to 23/2100Z: The geomagnetic field was quiet to unsettled due to a recurrent coronal hole high speed stream. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet to unsettled for June 24 -25. There remains the chance for isolated active periods. The geomagnetic field is expected to be quiet for June 26. III. Event Probabilities 24 Jun-26 Jun Class M 01/01/01 Class X 01/01/01 Proton 01/01/01 PCAF Green IV.
