Solar activity report
Any mentioned solar flare in this report has a scaling factor applied by the Space Weather Prediction Center (SWPC). Because of the SWPC scaling factor, solar flares are reported as 42% smaller than for the science quality data. The scaling factor has been removed from our archived solar flare data to reflect the true physical units.

Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 057 Issued at 2200Z on 26 Feb 2006IA. Analysis of Solar Active Regions and Activity from 25-2100Z to 26-2100Z Solar activity has been very low. Several low level
B-class events were observed from a region rotating onto the SE
limb.
IB. Solar Activity Forecast
Solar activity is expected to be very
low. An isolated C-class event is possible from the new oncoming
region.
IIA. Geophysical Activity Summary 25-2100Z to 26-2100Z
The geomagnetic field was primarily quiet with one period of
unsettled conditions observed at mid latitudes. The greater than 2
MeV electron flux at geosynchronous orbit reached high levels today.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be mostly quiet. Isolated unsettled to active
conditions are possible on 28 February and 01 March due to a small
recurrent coronal hole.
