Two small coronal holes faces Earth
Tuesday, 24 May 2016 18:10 UTC
Solar activity remains at low levels as we only have one numbered sunspot region on the Earth-facing solar disk. Most of the geomagnetic activity at Earth thus has to come from coronal holes and today we have yet another coronal hole facing our planet.

It's actually not one, but two smaller coronal holes that face Earth. We should start to feel the effects of their coronal hole solar wind streams in about 2 to 3 days from and a Kp of 4 (active geomagnetic conditions) can be expected. Sky watchers in Tasmania (Australia) and perhaps around the US-Canadian border should be alert for aurora when the solar wind stream arrives.
