Northern Lights Now – Coronal Hole Number 66 will be rotating into the Earth Strike zone over the next couple days. With the area covered by the coronal hole straddling the solar equator, there’s a good chance that the solar wind from this hole will impact Earth. Here’s a snapshot of the Sun Today in AIA 211 (Purple):
This coronal hole last was last pointed toward Earth on February 27. During that rotation, there was not a major response from the geomagnetic fields. The coronal has changed a bit since the last rotation so it is worth watching.
