Was extremely lucky to capture possibly the best Aurora Borealis show in a decade in Vancouver, Canada, on May 7th 2016. 
<p>We largely ignored the Proton Arc on the left side in the 2nd sequence thinking it was giant flash light or laser from the island. We learnt the next day, it was a freakin' Proton Arc (an even more rare phenomenon). Visible at 0.23s - 0.30s. 
The most intense part of the show (0.30s–0.40s) albeit short, was surreal and watching it with naked eyes felt scary as well as heavenly.
