Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. An Anticrepuscular Rainbow Fan Explanation: This is an unusual rainbow.
For one thing, the rainbow is not complete, appearing only in a sunlit fan — but that by itself is not very unusual. What is most unusual is the fake location of the Sun . The Sun appears to be toward the front, just below those hills — but it is not. That is not how rainbows work . Rainbows involve a backward reflection from falling rain , so that the Sun must really be behind you . In this case, gaps between clouds near the setting Sun allowed rays to cross the entire sky and appear to converge in front , an unusual phenomenon called anticrepuscular rays . The photo was taken with a phone last week at sunset in Presenzano , Italy . The seemingly reverse rainbow was noticed when hanging up laundry .
