As last time, there isn't much to speak of this time, although sunspot
region 837 has been growing fairly rapidly. At the present time,
however, it doesn't look at have the magnetic complexity to generate a
significant flare. The solar wind speed is mildly elevated and
meandering about the 500 km/sec range. Personally, I don't think
anything will come of it, but the folks at spaceweather.com are
suggesting that inhabitants of northern Europe, Alaska, and Canada
keep an eye out for aurora.
