Where is the best place to see aurora?
When geomagnetic conditions are very active aurora could be seen from anywhere within the UK but generally the further north you are in the UK the better your chances. You will need to find a location which is dark, so that means away from street lighting and other light pollution. You’ll also need a good, unobstructed view of the northern horizon, preferably from a height (e.g. a hill)
Otherwise you might consider going on holiday in the hope of seeing it. Places with good chances of seeing the aurora include Canada, Alaska, Iceland, and the Scandanvian countries. Of course, you’ll need to get the time of year right as well. Summer in those places will likely mean almost 24 hours of daylight and aurora can only be seen during darkness.
