Venus Rays & Shadows
Not the Moon but Venus.
Monika Landy-Gyebnar produced this animation. Look carefully above Venus to see cloud shadow rays sweeping anticlockwise as the cloud moves.
Solar and lunar 'crepuscular' rays are familiar - these from Venus are very possibly a photographic first.
The moving shadows and rays were visible by eye but Monika had to use
ISO 12500 to keep exposures short enough to capture them without much blurring. That added noise - The stills below were filtered through a noise reduction algorithm.

The shadows and rays are hard to see in stills - But they are there.
