A Moonbow!

Have you seen a rainbow at night?

Well to be honest, I have never seen one with my own eyes.

But luckily, a persistent astrophotographer from Kamuela, Hawaii has recorded this spectacular example long after dark:

In this picture, the bright moon played the role of sun, illuminating nightime raindrops falling through the damp Hawaiian air.

This long exposure image also revealed something even more rare: a secondary moonbow. It’s the faint ‘bow arciing above the brighter primary.

Primary rainbows are caused by single reflections inside raindrops; secondary bows are caused by double reflections.

It was a night to remember, indeed. 🙂
