Lunar halo over Oxford

I just came back from a long, tiring but very enjoyable day visiting the University of Southampton where I did my PhD. I went down there to give a talk and spent a long time chatting with the students and postdoc, and my former boss about a miscellany of ideas and possible resolutions to current problems. It was a positive visit and people seemed enthused by the talk.

It was also a good chance to catch up with an old friend that I see far too infrequently these days, so we went for a curry and chatted in one of our old haunts, while freshers drank themselves into a stupor around us.

I got back home to Oxford after taking four trains around midnight and saw, as I got into the drive, a halo around the moon. I got the tripod out and went into the back garden and took a few shots. The halo itself was delicate but lovely, made all the better by Jupiter, just to the bottom left of the moon. Uranus, just above Jupiter couldn't be seen with the flare from the moon.

While we're on the subject of atmospheric optics and ice halos I'll post up a photo I took from the airport in Vienna on Monday evening as the sun was setting and the plate crystals in the split cirrus clouds reflected and refracted the light toward me:

Tomorrow I head back to London to check on my visa situation, and then on to the wedding either tomorrow night or Friday early morning. In the mean time there are calculations building up which will be tackled in transit.
