View in the direction of Chamrousse on this 21-july 2011, joyeuse fête nationale!
As the sun shifts west, the shadow of the mountains is spreading further and enlighting the tiny rain droplets slowly falling on the head of the people in the town. The light scattered from the droplets gives rise to a few degrees of arc of two rainbows ( 2 orders :) ... unusual but nice!
do you see them both?
Video (accelerated x10) of the extinction of the rainbow as the sun shifts behind the mountains
