Red alerts usually indicate high probablity of Aurora Borealis, so if you're out and about later on tonight, take the odd glance upwards, especially if you're further north - displays often start with a light glow in the sky and can grow to something spectacular. I know we've been through a quiet period, but I did see a fairly spectacular display flying over Greenland a couple of weeks ago.
