Blast of Red

            Red aurora are rare enough to be special... 

"Green auroras occur at about 60 miles above Earth. Pure red auroras are much higher, from about 200 to 300 miles up, which allows people closer to the equator to see them. 

"An important gas remaining at that altitude is oxygen, and electrons that excite the oxygen atoms there produce a red light as pure as a laser."

- Ned Rosell - Science writer with the Geophysical Institute, University of Fairbanks Alaska.

Also, red aurora need to be 10 times more powerful than the more common green to be visible to the naked eye.
