Altostratus spreading across the sky over Bilbao, Spain
A wide range of contrails and dispersement as a result of varying atmospheric conditions, such as humidity, temperature, wind shear, and atmospheric and aircraft-induced turbulence. The clouds that are formed are done so via homogenitus and are dispersed wider in conditions of high humidity and high wind shear. This expansive display was captured by Ted Burrows over Lexington, Virginia, US.

Cirrus fibratus, which reminded Barbara that 'in moments of transition, perhaps it is best to keep your head in the clouds and follow the path provided. A straighter, truer course may not exist elsewhere.' This mesmerizing view was spotted over Black Mountain, Deming, New Mexico, US.
