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 176 Issued at 2200Z on 25 Jun 2006IA. Analysis of Solar Active Regions and Activity from 24-2100Z to 25-2100Z Solar activity was very low. New Region 897 (N06E75)
produced six B-class flares in the last 24 hours. The largest was a
B4 at 25/0505Z.
IB. Solar Activity Forecast
Solar activity is expected to be very
low. There is a slight chance of a C-class flare from Region 897.
IIA. Geophysical Activity Summary 24-2100Z to 25-2100Z
The geomagnetic field was quiet to unsettled.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet to unsettled for the first two days (26-27
June). A recurrent coronal hole is expected to rotate into
geoeffective position on 28 June. Unsettled to active conditions,
with possible minor storm periods, are expected.
