Analysis of Solar Active Regions and Activity from 04/2100Z to 05/2100Z: Solar activity was very low. No flares occurred during the past 24 hours. The visible disk was spotless. IB. Solar Activity Forecast: Solar activity is expected to be very low. IIA. Geophysical Activity Summary 04/2100Z to 05/2100Z: The geomagnetic field was quiet to unsettled. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be mostly quiet to unsettled with a slight chance for isolated active periods on day one (06 August) due to effects of a recurring coronal hole. Quiet conditions are expected on days two and three (07 - 08 August). III. Event Probabilities 06 Aug-08 Aug Class M 01/01/01 Class X 01/01/01 Proton 01/01/01 PCAF Green IV.
