Coronal hole faces Earth

A southern extension of the northern hemisphere polar coronal hole is now facing Earth. It extended far enough towards the south to trigger our automated coronal hole detection system.

It is hard to say how much of the coronal hole solar wind stream is going to arrive at Earth but the NOAA SWPC believes we will see the solar wind stream at our planet as they issued a minor G1 geomagnetic storm watch for this Thursday which would be 17 August, 2017.
