Aurora Alert - Sep 11

What a time for Lancaster University to upgrade their AuroraWatch software! While their site is down for an upgrade, we have had some of the biggest solar flares since 1976 and right now the planetary k-index is up to 7. What does that mean? It means that it is a great time to go outside and look for the northern (or southern) lights. These are usually visible from very high or very low latitudes (near the poles) but they are visible further south/north when there is more activity. The aurora have already been spotted from Sweden, the US, Canada and Ian is providing real-time information from Australia and Tasmania. Curse the UK weather. As always, if it is dark and cloud-free where you are, get yourself outside to have a look.
