Space Weather Prediction Center and the U.S. Air Force.

Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 166 Issued at 2200Z on 14 Jun 2012

IA.  Analysis of Solar Active Regions and Activity from  13/2100Z
to 14/2100Z:  Solar activity was moderate.  Region 1504 (S16E01)
produced a long duration M1/1n flare with maximum at 14/1435Z.  This
event was associated with a 1400 sfu Tenflare and a Type IV radio
sweep.  This region showed growth and maintained its
beta-gamma-delta magnetic configuration.  An associated CME was
observed in STEREO imagery at 14/1424Z with an estimated
plane-of-sky velocity between 900 and 1100 km/s.
IB.  Solar Activity Forecast:  Solar activity is expected to be
moderate.  An isolated M-class event is likely from Region 1504.
IIA.  Geophysical Activity Summary 13/2100Z to 14/2100Z:
The geomagnetic field was quiet.
IIB.  Geophysical Activity Forecast:  Geomagnetic activity is
expected to be quiet on 15-16 June.  An increase to unsettled to
active levels is expected early on day 3 (17 June) due to combined
effects from both the 13 June and 14 June CMEs.
