Rainbows are always seen in the direction opposite the sun, and of course so are anticrepuscular rays. These sun-rays are like the ones you sometimes see emanating from a cloud, or a sunset, but located on the side of the sky opposite the sun. Rainbows and anticrepuscular rays aren’t related, but – since both are seen on the side of the sky opposite a sunset or sunrise – it’s entirely possible to see them together. That was the case for Karl Diefenderfer in Quakertown, Pennsylvania on October 9, 2017, who said he caught them:
… as the remnants of hurricane Nate left southeastern Pennsylvania.
Thank you, Karl!
By the way, we featured another image similar to Karl’s recently, from Canada.
Bottom line: Photo of a rainbow with anticrepuscular rays.
