Analysis of Solar Active Regions and Activity from 18/2100Z to 19/2100Z: Solar activity was very low. Region 963 (S04W86) is the only spotted region on the disk and is rotating out of view. IB. Solar Activity Forecast: Solar activity is expected to remain very low. IIA. Geophysical Activity Summary 18/2100Z to 19/2100Z: The geomagnetic field was quiet. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be unsettled with active periods on day 1 (20 July) due to a recurrent coronal hole. Quiet conditions should return on days 2 and 3 (21-22 July). III. Event Probabilities 20 Jul-22 Jul Class M 01/01/01 Class X 01/01/01 Proton 01/01/01 PCAF Green IV.
