“Aurora is once again possible to similar latitudes, perhaps as far south as central or southern England should any larger storm periods occur.”
AuroraWatchUK, run by Lancaster University’s Department of Physics, is a real-time status tool that was on red alert last night. This meant there was a high likelihood of the aurora being visible from the UK.
The tool indicates at what time the lights are most likely to be seen in Britain, meaning it could be wise to check the site if you are eager to spot the Northern Lights tonight.
Most visible in a clear and dark sky, you will likely have to wait until after 5pm or 6pm, when the sun typically sets. But the best views could come at around midnight, normally the darkest hours of the night.
Royal Museums Greenwich states that “dark and clear nights, preferably with little light pollution, offer the best chance of seeing the aurora.”
