Reflection Rainbow at the Dutch isle Terschelling
It is not the brightness of this reflection rainbow that it makes special, but rather it is the almost complete absence of a normal rainbow: of the latter, only the base is visible. Just before this picture was taken, the photographer Günther Können saw both the reflection bow and the normal rainbow. By the time he got his camera ready the normal rainbow had gone. A cloud had blocked the direct sunlight to the rainshower. Reflected sunlight was still illuminating raindrops via a path under the cloud. The reflecting surface was a small lake about 200 m across and 1100 m from the photographer. The picture was taken on 18 Nov 2005 at the Dutch isle Terschelling, 16:05 CET. Solar elevation: 3 deg.
