Walnut Hill Treated To Rare Full Double Rainbow

March 29, 2008

Walnut Hill was treated to a complete double rainbow Saturday just before 6:00 pm.

Complete double rainbows that stretch across the horizon are actually considered to be rare, according to the Wikipedia. With a double rainbow, a secondary rainbow is seen, which is a second, fainter arc, outside the primary arc. In the second rainbow, the colors are in the opposite order, that is, with violet on the outside and red on the inside.

It is hard to see in these photographs, but the event included another even more rare phenomenon called a complete Alexander’s band…a darker area of sky between the two complete rainbow arcs. Light reflected in the rain in this area is reflected at such an angle that the observer is unable to see it all, creating the dark band.

We have also had emails that the rainbows were at least partial visible from Davisville, Bratt, Byrneville, Century, Atmore, Nokomis and Canoe.

We missed photographing the entire rainbow from side to side across the horizon. On a 35mm camera, it takes a 19mm or less lens; we only had a larger lens with us at the time. Scroll down for more photos. NorthEscambia.com exclusive photos, click to enlarge.
