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 2010IA. Analysis of Solar Active Regions and Activity from 11-2100Z to 12-2100Z Solar activity was moderate during the past 24 hours.
Region 1081 (N24W58) produced an M2.0/SN flare at 0057Z which was
associated with a Type II radio sweep and a weak CME (not earthward
directed). The region also produced a C6.1 flare at 0917Z. Region
1081 is a small D-type group and appears to be decaying slowly.
Region 1080 (S24W65) maintains a beta magnetic classification and
produced a C1.0 flare.
IB. Solar Activity Forecast
Solar activity is expected to be low
with a slight chance for an M-Class event for the next three days
(13-15 June).
IIA. Geophysical Activity Summary 11-2100Z to 12-2100Z
The geomagnetic field was quiet. The greater than 2 MeV electron flux
at geosynchronous orbit was at high levels during the last 24 hours.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to remain quiet for the next three days (13-15 June).
