I lived in Alaska for 4 years and the northern lights are amazing! I can say the most impressive part (to me anyway) was the fact there was NO noise! It was a great light show, with the wavy curtains of multi-colors in the night sky. Makes me wish I was back in Fairbanks.
Saw some great aurora pics on TV from Scotland last night. Someone who has seen one tell me something - when you see "curtains" of light moving across the sky, is that what you actually see, or is that time-lapse video?
