Analysis of Solar Active Regions and Activity from 02/2100Z to 03/2100Z: Solar activity has been very low. Region 950 (S12W32) was designated today. IB. Solar Activity Forecast: Solar activity is expected to be very low. IIA. Geophysical Activity Summary 02/2100Z to 03/2100Z: 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 again today. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be unsettled tomorrow (April 4) and quiet on April 5 & 6. III.
