Picture taken in August 2022. Fluctus, also known as Kelvin-Helmholtz wave clouds, form when wind shear causes instability in the (usually the upper) surface of a cloud. The formation is short lived and relatively rare. It can also only be seen well from the side like here. This video contains a good explanation of the physics involved here.
