Analysis of Solar Active Regions and Activity from 13/2100Z to 14/2100Z: Solar activity was very low. The visible solar disk remains spotless. IB. Solar Activity Forecast: Solar activity is expected to be very low. IIA. Geophysical Activity Summary 13/2100Z to 14/2100Z: The geomagnetic field has been quiet to unsettled. Solar wind speed remains elevated at approximately 680 km/s due to a coronal hole high speed stream. 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 (15 - 17 March). III.
