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 2008

IA. Analysis of Solar Active Regions and Activity from 23-2100Z to 24-2100Z

Solar activity was very low. The visible solar disk remained spotless.
IB. Solar Activity Forecast
Solar activity is expected to remain very low.
IIA. Geophysical Activity Summary 23-2100Z to 24-2100Z
The geomagnetic field was quiet. The greater than 2 MeV electron flux at geosynchronous orbit reached high levels.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to remain quiet from 25-26 February. Quiet to unsettled levels of activity are expected on 27 February as a recurrent coronal hole begins to become geoeffective.
