latest Solar wind storm and Geophysical Activity june 26 2012

Solar activity is fairly low with low level C-Class flares being detected around new Sunspot 1512. This region continues to slowly expand. Another sunspot is rotating into view off the northeast limb and looks to be the return of old region 1493 (now numbered 1513). Finally a third sunspot region is also rotating into view off the southeast limb. There will continue to be a chance for C-Class flares.
Solar and Geophysical Activity

IB.  Solar Activity Forecast:  Solar activity is expected to be low
through the period (27 - 29 June).

IIA.  Geophysical Activity Summary 25/2100Z to 26/2100Z:
The geomagnetic field was at quiet to unsettled levels with active to
minor storm periods detected at high latitudes. This activity was
associated with a minor increase in solar wind speeds (peak 496 km/s
at 26/0455Z) coupled with intermittent periods of southward IMF Bz
(maximum southward deflection -7 nT at 26/0113Z).

IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be at mostly quiet levels during days 1 - 2 (27 - 28
June). Field activity is expected to increase to quiet to unsettled
levels on day 3 (29 June) with a chance for active levels due to the
arrival of a co-rotating interaction region in advance of a coronal
hole high-speed stream.
