Analysis of Solar Active Regions and Activity from 15/2100Z to 16/2100Z: Solar activity was very low. No significant activity was observed during the past 24 hours. IB. Solar Activity Forecast: Solar activity is expected to be very low. IIA. Geophysical Activity Summary 15/2100Z to 16/2100Z: The geomagnetic field was quiet. The greater than 2 MeV electron flux at geosynchronous orbit reached high levels today. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet to unsettled for the next three days (17 - 19 July). III.
