Shown above is an impressive set of crepuscular rays captured above Turin, Italy on July 11, 2019. The Sun setting behind a curtain of cumulus clouds produced these fan-shaped rays. For such rays to be easily seen, the atmosphere must be rather dusty. Sunlight scattering off dust and other aerosols allows the projected rays to be readily observed. It’s likely that a high-pressure weather system over southern Europe in late June and early July played a role in keeping dust particles suspended in the atmosphere.
