About the colors: http://www.athropolis.com/arctic-facts/fact-nlights-color.htm "The colors of auroras are determined by the gases in the Earth's atmosphere, and incoming solar particles tend to collide with different gases at different heights. • Very high up (above 300 km / 185 miles), oxygen is the most common gas, and collisions there can create a rare red aurora. • The common yellow-to-green light is produced by collisions with oxygen at lower altitudes (between 100-300 km / 60-185 miles). • Around 100 km / 60 miles, nitrogen molecules produce a red light that often seems to form the lower fringes on auroral curtains. • Lighter gases high in the atmosphere, like hydrogen and helium, make blue and purple colors, but we cannot always see them in the night sky."

Someday I must see them with my own eyes, knowing that I will never reach your perfection.

These red ones I've posted here are all from the same night, that is the only time I've been able to capture these as fully red so far. I think I've seen these red auroras only twice in my life time... January 10, 2012
