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.
III. Event Probabilities 27 Feb-29 Feb
IV. Penticton 10.7 cm Flux
V. Geomagnetic A Indices
VI. Geomagnetic Activity Probabilities 27 Feb-29 Feb
A. Middle Latitudes
B. High Latitudes
