I hope you enjoy your trip. We seem to be some of the few people who didn't see the lights. We didn't realise they would be visible and went to bed. I've never seen them, but I can be happy for those who got this new experience. Digital cameras do pick up light frequencies that we can't see.
Don't get me started on the conspiracy nuts. They will exploit anything for attention.
To be fair HAARP has admitted they can artificially generate the aurora, but I don't think that was the case this past weekend. I'm sorry you didn't get to see them. I think a lot of people didn't know. The local news stations often mention there is a possibility, but usually once they do that it kills the chances. This was a rare exception. I have an app on my phone that I use to track the conditions and it sends me an alert when the chances are high that they might be visible.
