latest Solar flare and Geophysical Activity june13 2012

Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 164 Issued at 2200Z on 12 Jun 2012

IA.  Analysis of Solar Active Regions and Activity from  11/2100Z
to 12/2100Z:  Solar activity was low.  Regions 1506 (N11E38), 1504
(S17E28), and 1507 (S27E02) were the most active regions on the
disk.  Each region was responsible for multiple C-flares during the
period.  The largest of these came from Region 1506 which produced a
C2 flare at 12/0315Z.  All three of these regions have shown signs
of growth.  There were no Earth-directed CMEs observed during the
period.

IB.  Solar Activity Forecast:  Solar activity is expected to be low
to moderate.  There is a chance for an isolated M-class event from
Region 1504.

IIA.  Geophysical Activity Summary 11/2100Z to 12/2100Z:
The geomagnetic field ranged from quiet to minor storm levels.  Minor
storm levels were reached from 11/2100Z to 12/0300Z.  This was
followed by an active period from 12/0300Z to 12/0600Z.  Solar wind
observations indicated a sustained interval of negative Bz from
11/1500Z to 12/0200Z with peak values around -10nT.  In addition,
the data indicated a solar sector boundary crossing starting late on
the 11th.

IIB.  Geophysical Activity Forecast:  Geomagnetic activity is
expected to be quiet to unsettled on day 1 (June 13).  Quiet levels
are expected for 14-15 June.
