Report of Solar-Geophysical Activity

Issued: 2006 Oct 22 2200 UTC

Prepared jointly by the U.S. Dept. of Commerce, NOAA, # Space Environment Center and the U.S. Air Force.

Joint USAF/NOAA Report of Solar and Geophysical Activity SDF Number 295 Issued at 2200Z on 22 Oct 2006 IA. Analysis of Solar Active Regions and Activity from 21/2100Z to 22/2100Z: Solar activity has been very low. Region 917 (S05W46) now has a magnetic classification of Beta-gamma.

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

IIA. Geophysical Activity Summary 21/2100Z to 22/2100Z:

The geomagnetic field has been unsettled to active with one period of minor storming. Solar wind speed remains elevated though it has been slowly and steadily decreasing. Its current speed is approximately 550 km/s. The greater than 2 MeV electron flux reached high levels today.

IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be unsettled to active due to a recurrent coronal hole high speed stream. An isolated period of minor storming is possible.
