I have read recently that people have reported hearing sounds in connection with seeing the Aurora Borealis lights. They have described this sound as a type of clapping noise. Have you, in your experience of seeing the lights, heard any such sounds?
I have not heard any sounds like that while seeing the Aurora. They are also happening overhead during the summer, but we just can't see them with the 24 hour daylight. I'm guessing I would have heard them with all of the time I've spent outside this summer.
