This was filmed in the sky above London, UK on 17th June 2018.
Witness report: Weird, looked like it could be drones/birds/bats…
Long Description of Sighting Report
1. Watching tv in the living room after dinner.
2. My neighbour shouting for me to come outside as they couldn’t really make out what they we seeing from thier angle of the backyard.
3. Drones with LEDs/ Birds/ Bats but the light eminating from them just couldn’t be explained as either.
4. Swarming, rising and falling almost like birds but not.
5. Wowed…
6. They seemed to merge into the background and disappear.Author (source: MUFON)
Most definitely birds with reflected light from the moon.
A setting sun is still shining above the horizon but only reaching things that are high in the air. The same mechanism as noctilucent clouds.
They look like a flock of birds catching the sun’s dying rays.
I saw this same phenomenon in Broomfield CO in April of 2017 at lunchtime. I thought they were birds. The sky was blue and cloudless. As they got more close I could see that they were groups of triangles rotating on multiple common axes. They parked in the sky right in front of me. One group of triangles started to change from white, to silver, to light grey, to dark grey, to black and then ceased to be visible. I seemed like each group could be part of a larger object but it was blue sky between each triangle. There was no noise what so ever. As one group disappeared another would go thru this monochromatic sequence. It was not birds, or drones, or skydivers or common everyday aircraft.
I saw this same phenomenon at lunchtime in Broomfield CO in April of 2017. The sky was perfectly blue cloudless.I thought they were birds. As they got closer I could see they were groups of triangles rotating on multiple common axes. They stopped rotating and parked in the sky right in front of me. A group of triangles started changing from white, to silver, to light grey, to dark grey, to black and then ceased to be visible. No noise what so ever. I got the impression that each group of triangles were part of larger objects although it was blue sky separating them. As one group of triangles would disappear another group would go thru this monochromatic sequence. It was not birds or drones or skydivers or aircraft.
