Analysis of Solar Active Regions and Activity from 23/2100Z to 24/2100Z: Solar activity was very low. The visible disk remains spotless. IB. Solar Activity Forecast: Solar activity is expected to remain very low. IIA. Geophysical Activity Summary 23/2100Z to 24/2100Z: The geomagnetic field was quiet. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet 25 July and unsettled to active 26 July as a recurrent coronal hole becomes geoeffective. On 27 July conditions should range from quiet to unsettled. III. Event Probabilities 25 Jul-27 Jul Class M 01/01/01 Class X 01/01/01 Proton 01/01/01 PCAF Green IV.
