Joint USAF/NOAA Report of Solar and Geophysical Activity SDF Number 078 Issued at 2200Z on 19 Mar 2007 IA. Analysis of Solar Active Regions and Activity from 18/2100Z to 19/2100Z: Solar activity was very low. No new regions were numbered today. IB. Solar Activity Forecast: Solar activity is expected to continue at very low levels. IIA. Geophysical Activity Summary 18/2100Z to 19/2100Z: The geomagnetic field was quiet. 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 quiet. III.
