G1 storm, Incoming CME?

We reached the minor G1 geomagnetic storm threshold today thanks to the arrival of the anticipated coronal hole solar wind stream. The solar wind speed fluctuates around 600km/s and the direction of the IMF (Bz) is variable but does occasionally tip southward down to -10nT. These stats are very decent so a minor G1 geomagnetic storm watch remains in effect for the remainder of this day and tomorrow, 22 March 2017. There is however more to report so keep on reading!
