Have you seen a moonbow before? Tuesday, 11 August 2009 2:06 pm

NASA’s Astronomy Picture of the Day for yesterday (8/10/09) captures a moonbow, several rainbows, the starry sky visible in 2009 February over Patagonia in Chile.  I’ve never seen a moonbow before, have you?

Had stayed in Honolulu for almost 5 years before moved to mainland, I’ve seen plenty of rainbows (you’ll see a lot if you stay on the campus of the Univ of Hawai’i at Manoa).  As you can see, moonbows are lit by the moon just as rainbows are lit by the sun.  Both rainbows and moonbows are created by light being scattered inside small water droplets, typically from a nearby rainfall.  It’s still fascinating to see it … even in a video.
