Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 126 Issued at 2200Z on 06 May 2007
IA. Analysis of Solar Active Regions and Activity from 05/2100Z to 06/2100Z: Solar activity was very low.
IB. Solar Activity Forecast: Solar activity is expected to be very low.
IIA. Geophysical Activity Summary 05/2100Z to 06/2100Z: 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 to unsettled 07-08 May due to a recurrent coronal hole high speed stream. On 09 May the geomagnetic field is expected to be quiet.
