Glancing CME and solar wind

Hi all,

A glancing blow from a recent CME produced a significant geomagnetic effect and this was quickly followed by fast flowing solar wind from a large coronal hole, as has been reported on Spaceweather.com

My magnetometer responded with some nice peaks and those lucky enough to be in the right place at the right time were treated to beautiful aurora.

Thanks for looking.

Thanks Stu. The big coronal hole with many rotations from a while ago seems to have eroded away, to be replaced by these active regions and spots we have had for these spots for the last couple of rotations...

Thanks, Mark. I might track back and chart the evolution of some of these features.

Cheers.
