Moon Dog (while waiting for eclipse)

You may have heard of Sundogs, rainbow coloured patches of light that occur 22º form the Sun when plate shaped hexagonal ce crystals in cirrus clouds refract light hen the Sun is low to the horizon.

Well, the same effect occurs with the Moon, here's a Moon Dog I got tonight just after Moon rise, while waiting for the penumbral eclipse later tonight. Jupiter is the dot off to the bottom right of the Moon (click to embiggen for parselenial goodness). 8 second exposure at 400 ASA, canon IXUS.
