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

When Mastodon Collections are more widely rolled out I'll plan to make at least one.
I had created a net/sec ops/rd list a few years ago. It is out of date. Obviously and sadly so when you see who was the first to add themself to the list after me.
Feel free to add yourself to the original list if you want and don't despise a Google form enough. Looking forward to the collections feature.
