Aurora Skyline

Seems like too long since we have had any good Auroral activity up here corresponding with clear skys. Lets hope the next few months bring some activity. This is a shot from 2017 of the Aurora Borealis or Northern Lights in Mt Robson Provincial Park. The red/pink band of forms at around 250 – 500 km altitude from high energy state excited oxygen atoms emitting light at 630 nm. The bottom layer is the more typically seen green aurora that forms between 100 – 250 km altitude by excited oxygen atoms emitting light at 557.7 nano-metres. I like the way the green band follows the terrain here, there is no reason for that as the aurora is in no way related to the topography, it was just a lucky coincidence.

This was the same night and location that I took my shots of STEVE to the south over Berg Lake and Mt Robson from the same position (the shot above is looking north). I have included a shot below from the same position looking south.

To learn more about STEVE or see a time-lapse of the above shot you can check out my "Who is STEVE" post https://steempeak.com/@intrepidphotos/who-is-steve

Likewise I have some more information on the "true" colours of an Aurora and some suggestions on what white balance to use when shooting Aurora in my post here https://steempeak.com/photofeed/@intrepidphotos/crooked-river-aurora

If you would like to learn a little bit more about my background in photography you can read the interview @photofeed did with me here
