Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 054 Issued at 2200Z on 23 Feb 2006
IA. Analysis of Solar Active Regions and Activity from 22/2100Z to 23/2100Z: Solar activity was very low. The visible solar disk remains spotless.
IB. Solar Activity Forecast: Solar activity is expected to continue at very low levels.
IIA. Geophysical Activity Summary 22/2100Z to 23/2100Z: The geomagnetic field was mostly 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 with the possibility of an isolated active period on 24 and 25 February. On 26 February, quiet to unsettled conditions are expected.
