Question

How do I create a lunar rainbow?

Answer 1

Moonbows are most easily viewed when the moon is near to full (when it is brightest). For other than those produced by waterfalls, the moon must be low in the sky (less than 42 degrees and preferably lower) and the sky must be dark. And of course there must be rain falling opposite the moon. This combination of requirements makes moonbows much more rare than rainbows produced by the sun.

Answer 2

What is lunar rainbow? Do you mean the colorful halo you sometimes see around the moon?

I read somewhere that is caused by ice particles high in the atmosphere.
