Hof, the cultural house with Auroras on top

I was so lucky when I shot this one ....
I had gone out to drive my stepson to meet a learning group. Luckily I had my tripod in the car. (I always have my camera with me)

I had seen a little green in the sky earlier that evening. So when I was driving back home I suddenly took another turn than I was supposed to (just like someone took over my decisions and told me to check out the lights at this particular location)
I did .... and VOILA !
