Whoa! Great photographic persistence story and results! It's not luck getting great photos, It's being there at the right time with the right equipment and pulling it off. No great shots off the couch I always mention to wannabe photographers. Good story and good job plus you had the neat experience of being blown away as a side effect.
Max, the old photographer.
BTW, Northern lights have even reached into SE Kansas a few times in my life. I recall as a kid seeing a red Northern sky several times and even a few decades ago Kansas was bombarded with a couple of spectacular nights of first class shafts, waves and colors. Good show!
