Coronal hole faces Earth

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:

A transequatorial coronal hole is facing Earth. Enhanced solar wind could arrive in ~3 days. Follow live on https://t.co/bsXLidnzGh pic.twitter.com/cpyxI8XgJa

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.
