Coronal hole faces Earth

A southern extension of the northern polar coronal hole is now facing Earth. An enhanced solar wind stream should interact with Earth's magnetosphere during the first half of Monday, 9 November.

The coronal hole solar wind stream will likely arrive at Earth as the effects of the M3.7 solar flare coronal mass ejection which is expected to arrive late on Saturday, start to wane. The M3.7 coronal mass ejection is predicted to cause minor G1 geomagnetic storming conditions, and we can not exclude that also this coronal hole will also cause minor G1 geomagnetic storming conditions on Monday, when the stream arrives.
