Bochum Twinned Rainbow

On June 9, 2009, another twinned rainbow appeared in the skies over Bochum, Germany. The phenomenon only lasted less than a minute, and I could watch the “twin ettect” move from left to right through the rainbow.

This picture has been processed to make the effect more obvious, but here is another picture showing how it really looked (1).

Just after the “twin effect” had disappeared, the rainbow reached a stunning brightness making supernumeraries visible as well as Alexander´s Band (2).
