Well the best time to se the northen light is in november december january and february. And go with Hurtigruten www.hurtigruten.com its the most beautiful sea voyage. And you will sure see the northen light when you come up north. You can sail from Bergen and up to Kirkenes and if you go in January that I would really reccomend then you will have the sun in Bergen and day light and further north it will be darker and untill its dark all day long and the Northen Light play in the sky. Its fantastic.
Just read an article on this and March is supposed to be the best time.
