Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 104 Issued at 2200Z on 13 Apr 2008
IA. Analysis of Solar Active Regions and Activity from 12/2100Z
to 13/2100Z: Solar activity was very low.
IB. Solar Activity Forecast: Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 12/2100Z to 13/2100Z:
The geomagnetic field was quiet to unsettled. Solar wind velocity
remains elevated in the 550 - 600 km/sec range. 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 at mid-latitudes for the forecast period, 14-16
April. Isolated active to minor storm conditions at high-latitudes
remains a possibility due to the elevated solar wind velocity.
III. Event Probabilities 14 Apr-16 Apr
Class M 01/01/01
Class X 01/01/01
