Rare Moonbow over Ben Hiant

Moonbows are rare but this one formed this morning, just before six thirty, as the waning full moon set in the west and a shower of rain scattered the light so a lunar rainbow formed over Ben Hiant.

To the human eye the moonbow appears white but the camera picks out the spectrum. They're rare because, being so faint, they often pass unnoticed. Formed by sunlight reflected off the moon, this one was surprisingly bright and, moments before this picture was taken, made a complete arc across the eastern sky.
