Astronomy Picture of the Day -- A Full Circle Rainbow over Australia
NASA ^ | September 30, 2014 | (see photo credit)

Explanation: Have you ever seen an entire rainbow? From the ground, typically, only the top portion of a rainbow is visible because directions toward the ground have fewer raindrops. From the air, though, the entire 360 degree circle of a rainbow is more commonly visible. Pictured here, a full circle rainbow was captured over Cottesloe Beach near Perth, Australia last year by a helicopter flying between a setting sun and a downpour. An observer-dependent phenomenon primarily caused by the internal reflection of sunlight by raindrops, the 84-degree diameter rainbow followed the helicopter, intact, for about 5 kilometers. As a bonus, a second rainbow that was more faint and color-reversed was visible outside the first.

I saw one once from a high rise office building. The circular rainbow was about 1/2 mile away or less.
It was very cool — once in a lifetime stuff.

Not just a full-circle rainbow, but a double! Magnificent.

Yep. In a helicopter over Sumatra, Indonesia - we flew thru it. The rainbow encircled us. Back in the mid 70s.

It’s not bad at all, and I”m not a fan of these terrestrial shots in APoD.
