Astral Arcadia

As the ethereal glimmer of twilight overtook the sunset last Tuesday evening (21.07.09) noctilucent clouds once again danced across the sky above Stenhousemuir. This was a beautiful display that extended it’s fibrous like body at least 60° to 70° across the north eastern horizon.

Having had a chance to study the two photographs I managed to take more closely I’d say that this was a Type 5 formation featuring what looks like Type P (waves crossing a band), and Type IIIb (waves with undulations) structures. A combination that made for a breathtaking sight.

    I finally realized what these look like: glowing spider webs! Beautiful images, Ewan!

    Thanks Aaron. This was to be — at least for me — the last NCL display of the summer, and what a display! It really was a wonderful sight.
