Bright triangle-shaped was caught on tape in the sky above Piotrków, Poland on 7th December 2020.
Witness report: Submitting on behalf of my friend, who’s also a trainee pilot and his partner. Object spotted by his partner first, who thought there’s something burning, then thought its a moon, but excluded that possibility after observing moon on a different spot in the sky. Object hovered for a long time, pulsating slightly. At some point blinked and disappeared. then reappeared again with its twin for a moment (there were two of them at the same time for a brief moment) and just disappeared for good after another 20 min or so of hovering there. Aerial map of the spot attached.
