I've seen the Northern Lights a few times in my life, all of them since I moved to Wisconsin in 1996. The most spectacular displays I saw were back in the early-2000s. Unfortunately, phones didn't have cameras back then and digital cameras were expensive and finicky, so we never got pictures of those. But they were visible enough in the middle of Madison that we woke our kids up to come out and see them. I think we were home-schooling them at the time, so we could let them sleep in the next day. There were vivid blues, bright greens, and the occasional pink, and they fluctuated wildly across the sky. We could see all of this with the naked eye, they were so intense.
A few weeks ago, we caught a display, this time with our phones. Unlike the flashing display we saw back in the early aughts, these were difficult to see with the naked eye, but looking through our phone cameras, we were able to catch them. I'm including a couple of the better pictures below, along with a short video, for your viewing pleasure. It's worth staying up late and going out and seeing these displays (though we caught these right in our back yard). Enjoy.
