This spherical incandescent light appeared between some trees in a valley near La Roche-en-Ardenne, Belgium. The light was stationary and the fact that it got weaker when viewed from a slightly different angle, indicates that it was caused by sunlight reflecting off a mirrored surface. Unfortunately, it was impossible to found out what precisely caused this reflection.
