Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 237 Issued at 2200Z on 24 Aug 2008
IA. Analysis of Solar Active Regions and Activity from 23/2100Z to 24/2100Z: Solar activity was at very low levels. The visible disk remained spotless.
IB. Solar Activity Forecast: Solar activity is expected to remain at very low levels.
IIA. Geophysical Activity Summary 23/2100Z to 24/2100Z: The geomagnetic field was quiet. The greater than 2 MeV electron flux at geosynchronous orbit was at high levels.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet during the forecast period (25 – 27 August).
