Did you see this rainbow-colored image in the sky on Thursday evening? A reader sent in this photo, taken in Amagansett, in the hopes of finding out what it was.
We asked George McKillop, a Westhampton resident and Deputy Chief Hydrologist for NOAA, and he said it's either a sundog or a sun pillar. It occurs because the sunlight is being reflected off ice crystals in the sky.
An atmospheric phenomenon, sun dogs create bright spots of light in the sky, as a colored patch of light to the left or right of the sun. Sun pillars are a visual phenomenon when light is reflected from crystals of ice and the light comes from the sun, usually lower on the horizon.
Tell us if you saw it or if you have a different opinion of what it is.
