Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 220 Issued at 2200Z on 08 Aug 2006

IA. Analysis of Solar Active Regions and Activity from 07/2100Z to 08/2100Z: Solar activity was very low. New Region 903 (S09E56) was numbered today.

IB. Solar Activity Forecast: Solar activity is expected to remain at very low levels.

IIA. Geophysical Activity Summary 07/2100Z to 08/2100Z: The geomagnetic field was quiet to active. Solar wind speed at ACE remains elevated at around 600 km/s. 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 quiet to unsettled with isolated active periods possible on 09 August. On 10 and 11 August, quiet to unsettled conditions are expected.
