AW: [APML] Aurora Colors

Not really an answer to your question, but I've seen a white aurora (parts
of one), and to my surprise, it showed yellow on the photos.

Betreff: [APML] Aurora Colors


I read somewhere what causes each aurora color but of course I lost it. Does
anyone here know what each color represents, which ionized gas, level of
ionization, exact emission lines? I have never seen a white aurora, is this
just red green and blue all together?
