A Colorado witness reports a "black triangular object with three lights on two sides moved north to south with no sounds" and then directly overhead on October 18, 2011, according to October 19, 2011, testimony from the Mutual UFO Network (MUFON) witness reporting database.

"It moved slightly bearing southeast," the witness stated. "It passed between two trees. I then saw the side - three orange coloured lights - then it changed angles. I was able to see two sides with three lights each. It made no noise as it faded into the horizon at great speed."

The witness also reports an odd look to the bottom of the craft.

"There were no lights on the bottom at all. There was a strange haze around the ship like a magnetic field around it."

No town name was mentioned in the public portion of the MUFON report. No images or videos were included with the report. The above quotes were edited for clarity.

Another case from the same date was covered recently: Colorado: 'Triangular-shaped blob' morphs shape.
