Three mysterious lights were seen hovering over the western part of Phoenix, Arizona, on the night of Sept. 18.

The lights were captured on video by Tony Aguilera, a photographer from Phoenix, around 11 p.m. He posted the footage on YouTube, referring to the lights as “orange orbs” in the video description.

Aguilera said his neighbor knocked on the door and pointed out two orange lights in the sky, but before Aguilera could start filming them, they vanished. They reappeared in a different spot a few minutes later, and this time he was ready with a camera.
