Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 219 Issued at 2200Z on 07 Aug 2006

IA. Analysis of Solar Active Regions and Activity from 06/2100Z to 07/2100Z: Solar activity was very low. No new regions were numbered today.

IB. Solar Activity Forecast: Solar activity is expected to be very low.

IIA. Geophysical Activity Summary 06/2100Z to 07/2100Z: The geomagnetic field ranged from quiet to major storm conditions. Activity was due to a solar sector boundary crossing followed by a coronal hole high speed stream.

IIB. Geophysical Activity Forecast: The geomagnetic field is expected to continue to be quiet to active with minor storm periods possible at higher latitudes on 08 August. On 09 and 10 August, conditions are expected to be quiet to unsettled.
