Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 163 Issued at 2200Z on 12 Jun 2010
IA. 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).
