Aurora alert april 12/13

A fast solar wind is buffeting the Earth at present and is being felt as far south as Ireland. As you can see from my magnetometer, activity started about 19:00 bst (18:00UT) and is continuing as I type. Do go out and check your northern horizon for signs of aurorae.

  2. Thnx Brian glad you got the alert. And what amazing colours! This type of event is unpredictable and can happen at any time, I was surprised to see the mag jump like that as solar activity is very low at present.
