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 084 Issued at 2200Z on 25 Mar 2007IA. Analysis of Solar Active Regions and Activity from 24-2100Z to 25-2100Z Solar activity was very low.
IB. Solar Activity Forecast
Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 24-2100Z to 25-2100Z
The geomagnetic field was quiet to active. Solar wind speed is
slightly elevated due to a recurrent coronal hole high speed stream.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet to unsettled with isolated active periods for
the next three days due to the recurrent coronal hole high speed
stream.
