Hurgiegen do northern lights cruises and they advertise that they give you a free cruise if you don't see them! .... as a way to reduce the hardships and hedge your bets that sounds like a winner! ..... in terms of avoiding disappointment due to terrestrial weather it's reckoned Finland is the best mix of accessibility and likelyhood of viewing.

For me, they appear here at the house reasonably frequently .... and with the cycle being on an upswing for the next 4 or 5 years I'll just make a pot of tea and wait for them to come to me 🙂
