Analysis of Solar Active Regions and Activity from 06/2100Z to 07/2100Z: Solar activity was very low. No flares were observed during the past 24 hours. The solar disk remains spotless. IB. Solar Activity Forecast: Solar activity is expected to be very low. IIA. Geophysical Activity Summary 06/2100Z to 07/2100Z: The geomagnetic field was quiet. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet to unsettled for the next three days (08-10 April) due to a recurrent coronal high speed stream. Isolated active conditions at mid latitudes and minor storming at high latitudes are possible on 09 April. III.
