Rainbow Over The Rip

Summary Authors: Phil Thomson; Jim Foster
The photo above shows a rainbow that seems to have it all; vibrant colors, primary and secondary bows, supernumerary bows, and even faint anticrepuscular rays. It was taken on July 29, 2012, after a mid-morning rain shower swept across the waters of The Rip at Queenscliff (Port Phillip Heads) on the Bellarine Peninsula, Victoria, Australia. This is the winter season down-under, so the Sun is fairly low in the sky at mid-morning. Once the showers passed by, a high arching bow soon took shape. Rain showers having the biggest drops produce the richest colors. It's evident that clouds were both opposite the Sun, as they must be for a rainbow to appear, and in the immediate vicinity of the Sun, as they must be to give rise to anticrepuscular rays.
Photo details: Pentax K5 camera; 1/25 sec. exposure; f13; ISO 100; Pentax 18-55 mm lens; two RAW images edited in ACDSee Pro5 then stitched together in Panorama Maker Pro4.
