Coronal hole faces Earth

A coronal hole is facing our planet today and sending a high speed solar wind stream towards our planet.

Our automated coronal hole detection system did its job and detected the coronal hole. An alert was send to the mobile app and our Twitter account:

This coronal hole has been around for many months now in all kinds of shapes and sizes. During the previous rotation this coronal hole caused geomagnetic storm conditions up to moderate G2 level. STEREO shows that the intensity of the coronal hole solar wind stream might not match what we've seen during the last rotation but minor G1 geomagnetic storm conditions remain possible. The solar wind stream flowing from this coronal hole could arrive on Saturday, 1 December.
