Well, apart from 11 hours in the office spending lots of time chatting physics, I was witness to a partial solar eclipse, a 22 degree solar halo, an upper tangent arc and a circumzenithal arc. I only have the first three on camera, but I can promise that the fourth was spectacular. Most of the time the solar halo was completely behind clouds this morning, but I was able to get this one shot. Not the greatest shot ever (and NOTHING compared to this), but still:
When going for lunch later, the Cheshire Cat halo was out, but my camera was not. Still, not bad for the first day in Munich!
