Yesterday's mystery #cloud has been ID'd as #cirrocumulus (or perhaps altocumulus) but in any case of the rather rare #undulatus variety, with the waves caused by wind shear at different altitudes: https://cloudappreciationsociety.org/october-2023/ comes somewhat close; see https://cloudappreciationsociety.org/cloud-library/undulatus/ and https://cloudappreciationsociety.org/cloud-library/cirrocumulus/ for details. h/t https://scicomm.xyz/@drlucyrogers@mastodon.social
