Analysis of Solar Active Regions and Activity from 01/2100Z to 02/2100Z: Solar activity has been very low. IB. Solar Activity Forecast: Solar activity is expected to be very low. IIA. Geophysical Activity Summary 01/2100Z to 02/2100Z: The geomagnetic field was active with periods of minor storming due to a recurrent 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 unsettled to active on April 3 and quiet on April 4 & 5. III.
