Rainbow Gallery

This is the Rainbow Image Gallery from a site called Atmospheric Optics which is interesting because it talks about all kinds of different atmospheric effects, from sundogs, to moonbows to rays and shadows. It is also takes the time to describe the actual atmospheric phonomenon and what causes it.

The gallery also has a great picture of nacreous or "mother of pearl" clouds in Antartica, which has been in the news as of late for their surreal look.
