It's called 'distrail'.
Not cirrus, but a supercooled water cloud. eg. altostratus.
Thanks for the clarifications.
Lots of contrails over the French Alps on Tuesday, including several loops. I didn't get a good look at what was making them as it was was often hidden behind the mountains. Maybe Airbus test flight again? In the first pic if you zoom in you can see the more distant loops to the left of the mountain.
There were circles and spirals in the sky for much of the middle of the day.
Nice day at Sierra at Tahoe today. Good day for contrails at various altitudes. Been up the last two days with very few visible contrails. Weather has been crystal clear and warm. Seems like a pressure change and some temp drop on the way. Weather forecasted in the next few days. Hope you aircraft trackers have fun identifying these flights. Mostly just air traffic on a day where conditions make it look sinister?
Lots of contrails this morning, and some striking shadows where the trails lined up with the rising sun.
Edit to add screenshot showing the high humidity over much of the UK this morning. I'm in the red circle:
There was an almost identical photo (bottom left) posted on Chemtrails Global Skywatch yesterday from someone living in Bracknell:
Interesting to see the same trails from a slightly different perspective:
Contrail shadow from my back garden a few minutes ago. The clouds are moving quite fast so it was only aligned to make the "beam" for 20-30 seconds.
Aligned perfectly with the sun:
Some stonking great trails the evening!
Stopped on the way to the station this morning to grab this photo of two long trails and a short one:
I didn't have time to ID the flights there and then but have just checked it out:
The photo was taken from the red dot in Farnborough, looking just south of west (the front of the house faces pretty well due east). The two persistent trails are BY1360 and DY4275, at 35,000ft and 34,000ft respectively, and the non-persistent one is DL411, at 37,000ft.
Not much height difference needed for a big change in the appearance of the contrails.
I think this is a distrail ?? on the edge of some clouds. the sun is setting so I think if it was a shadow it is on the wrong spot ?? (the dirt smudges are either my window or something with the camera up against the window)
Looks like a distrail, but there's also a contrail there - so it's more like the gap left by a contrail (probably aerodynamic) forming in or above a layer of clouds. It's in a very thin layer round the sides, so it gives the illusions of looking like it forms one edge of the cloud layer.
This contrail last night spread out in quite an unusual way.
Separate names with a comma.
