Frankfurter Blauer Mond (Frankfurt Blue Moon).
Frankfurt am Main, Germany. Those are the Taunus mountains in the background.
This isn't in perfect focus and it unfortunately has a reflection from the window pane, but I managed to get one decent photograph of the Blue Moon over Frankfurt to share with you.
Are those mountains in the distance? Any interesting geology/paleontology close by?
It's beautiful! I love the placement of the moon.
