Northern Lights Now – SWPC has issued yet another geomagnetic storm watch. This time the period for potential Aurora is September 13 and 14, with G2 (KP=5.67 and above) on the 13th and G1 on the 14th.
Avid space weather followers may attribute this watch to the big X-class from from 9/10, but this storm is the result of CIR and the following high speed solar wind from a coronal hole.
This is a brief update. We will post more later.
