A http://en.wikipedia.org/wiki/22%C2%B0_halo is a optical phenomenon that can be seen around both the sun and moon as often as 100 times a year. The effect happens when light from the sun or moon passes through ice crystals int he upper atmosphere and forms a prism, similar to a rainbow but at different angles.

I'm not sure if this is possible and I think it may be difficult with 2 moons but if it can be pulled off it would be amazing.
