What we didn't realise when staying in Fairbanks was that we'd caught the beginning of the northern lights season - Fairbanks gets this about 240nights a year, not bad eh? We only realised whilst talking to another camper from South Africa - so a couple of night ago we vowed to stay up. We were lucky and managed to see something too! What started of as a whitish glow got greener as it got darker and moved across the sky over the course of about 30 minutes:
We set the alarm clock for 2am, but it had clouded over by then. We didn't see the full on green/red etc. apparently it gets better as the season goes on, but then we couldn't hang around - it was getting colder!
