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.

SDF Number 054 Issued at 2200Z on 23 Feb 2006

IA. Analysis of Solar Active Regions and Activity from 22-2100Z to 23-2100Z

Solar activity was very low. The visible solar disk remains spotless.
IB. Solar Activity Forecast
Solar activity is expected to continue at very low levels.
IIA. Geophysical Activity Summary 22-2100Z to 23-2100Z
The geomagnetic field was mostly 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 with the possibility of an isolated active period on 24 and 25 February. On 26 February, quiet to unsettled conditions are expected.
