Analysis of Solar Active Regions and Activity from 23/2100Z to 24/2100Z: Solar activity was very low. Region 1000 (S12W57) remains spotless. No flare activity occurred during the past 24 hours. IB. Solar Activity Forecast: Solar activity is expected to be very low. IIA. Geophysical Activity Summary 23/2100Z to 24/2100Z: The geomagnetic field was at quiet to active levels . The solar wind speed gradually declined to around 500 km/s. 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 mostly quiet through the forecast period ( 25 July to 27 July). III.
