OT Aurora Borealis.
Irwin, the Aurora picture was taken in Grande Prairie, Alberta, Canada, in about 1979/80 or so. I had several pictures but the one behind the tree was the best.
I am not sure if my imagination was playig tricks on me that night but I swear I could hear the plasma crackle in the absolutely wind still atmosphere. It was as if I could reach out my hand and touch the moving waves. The coulors were far more intense(purple and green etc.) than they are shown on the picture.
