The event occurred at 9:30 p.m. on August 30, 2018.
“I was looking at the sea from my house, when suddenly on the horizon I saw three white lights forming a triangle in ascending path from south to north,” the witness stated. “The separation of the lights was like the size of more than one coin. The three lights rotated together slowly as if they were a single, triangular object until reaching almost above my city. The triangle became smaller and smaller, rotating and becoming a unique object light above the clouds until it was totally covered, and I stopped seeing it.”
MUFON CAG Investigator for Portugal, Ken Pfeifer, closed this case as an Unknown Aerial Vehicle.
