COMMENT: The NOAA AR 1013 (not classified as a sunspot group by
Catania) has produced an A3.2 flare peaking at 07:14 UT this morning. It
was accompanied by an EIT wave and dimming event starting at 07:09 UT.
The associated CME was weak and narrow. We do not expect it to arrive to
the Earth. This morning the Earth entered the interaction region between
slow and fast solar wind streams. The fast stream was most probably
produced by a low-latitude extension of the southern polar coronal hole.
The southward component of the interplanetary magnetic field stayed
below 5 nT, so the geomagnetic conditions remained quiet. Currently the
solar wind speed is around 600 km/s and the interplanetary magnetic
field magnitude is 5-6 nT. Quiet geomagnetic conditions are expected,
with isolated intervals of K = 4 possible but unlikely.
