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 055 Issued at 2200Z on 24 Feb 2006IA. Analysis of Solar Active Regions and Activity from 23-2100Z to 24-2100Z
Solar activity was very low. The visible solar disk
continues to remain spotless.
IB. Solar Activity Forecast
Solar activity is expected to continue
at very low levels.
IIA. Geophysical Activity Summary 23-2100Z to 24-2100Z
The geomagnetic field was mostly quiet to unsettled with an isolated
active period between 24/1200 to 24/1500 UTC at several
observatories. The greater than 2 MeV electron flux at
geosynchronous orbit was at high levels again today.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet to unsettled with an isolated active period
possible on 25 February. Quiet to unsettled conditions are expected
on 26 and 27 February.
