Cirrus homogenitus as a result of aircraft condensation trails, also known as contrails, in the upper atmosphere. When these types of clouds persist and evolve towards a more natural appearance, its cloud classification changes from homogenitus to homomutatus. This example was spotted over Abergavenny, Wales.

Remnants of contrails that form into high level cirrus clouds via homogenitus, which is when clouds develop as a result of human activity such as from aircraft condensation trails; i.e., contrails. In this instance, it has taken on the look of "feathers" in this view near El Dorado Hills, California, US.
