Analysis of Solar Active Regions and Activity from 18/2100Z to 19/2100Z: Solar activity was very low. New Region 1083 (N19W22) was numbered today and is a small simple B type sunspot group. IB. Solar Activity Forecast: Solar activity is expected to be very low with a slight chance for an isolated C-class event. IIA. Geophysical Activity Summary 18/2100Z to 19/2100Z: The geomagnetic field has been quiet. The greater than 2 MeV electron flux at geosynchronous orbit was at high levels today. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet. III. Event Probabilities 20 Jun-22 Jun Class M 01/01/01 Class X 01/01/01 Proton 01/01/01 PCAF Green IV.
