Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 057 Issued at 2200Z on 26 Feb 2008
IA. Analysis of Solar Active Regions and Activity from 25/2100Z
to 26/2100Z: Solar activity was very low. The only region on the
visible disk is Region 983 (S06W54).
IB. Solar Activity Forecast: Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 25/2100Z to 26/2100Z:
The geomagnetic field was 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 on day one (27 February).
Unsettled to active conditions are expected on days two and three
(28 - 29 February) with isolated minor storm levels possible at high
latitudes. The increase in activity is due to a recurrent coronal
hole high speed wind stream.
