Analysis of Solar Active Regions and Activity from 13/2100Z to 14/2100Z: Solar activity was very low. The visible disk remained spotless. IB. Solar Activity Forecast: Solar activity is expected to remain very low. IIA. Geophysical Activity Summary 13/2100Z to 14/2100Z: The geomagnetic field was quiet to unsettled. The recurrent coronal hole high speed stream remained geoeffective. Solar wind speed measured at the ACE spacecraft ranged from approximately 650 km/s to 730 km/s. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be unsettled on Day 1 (15 July), becoming quiet on Day 2 (16 July). Activity is expected to be quiet to unsettled on Day 3 (17 July). III. Event Probabilities 15 Jul-17 Jul Class M 01/01/01 Class X 01/01/01 Proton 01/01/01 PCAF Green IV.
