Suns eclipsed in a lab library

by Claudine Vanbauce, Université de Lille / Laboratoire d'Optique Atmosphérique, Lille, France

During the solar eclipse January 4, 2011. Partially eclipsed sun cast on a wall (Laboratoire d'Optique Atmosphérique library) through an openwork blind which acts as a stenope.
