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 163 Issued at 2200Z on 12 Jun 2007IA. Analysis of Solar Active Regions and Activity from 11-2100Z to 12-2100Z Solar activity was very low. Region 960 (S05W71)
continues to decay and is now classified as a magnetic alpha sunspot
group. It produced a B3 flare at 12/1931Z.
IB. Solar Activity Forecast
Solar activity is expected to be very
low. There remains a chance for an isolated C-class flare from
Region 960.
IIA. Geophysical Activity Summary 11-2100Z to 12-2100Z
The geomagnetic field was quiet.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet on 13 June. Expect quiet to active conditions,
with isolated minor storm periods possible at high latitudes, on
14-15 June as a recurrent coronal hole rotates into a geoeffective
position.
