A Pennsylvania witness watched a slow moving object under 600 feet that silently crossed the sky with "four large, bright white lights and two blinking lights" on December 15, 2010, according to testimony from the Mutual UFO Network (MUFON) witness reporting database.

The object was first observed moving about 5 mph and was "about 200 yards up" in the sky.

The witness stated that the object was larger than a plane.

"There were four large, bright, white lights and two blinking lights - one blue, the other red," the witness stated. "It continued to move very slowly and silently across the sky and as it approached the highway it sped up effortlessly to around 50 mph or so."

No town name was mentioned in the public portion of the MUFON report, which was filed on December 20, 2010. No images or video were included with the report.

The following is the unedited and as yet uninvestigated report filed with MUFON.

Pennsylvania, December 15, 2010 - Strange lights, object moving very slowly and silently across sky. MUFON Case # 27051.

I turned left off of Auction Road went through the covered bridge, turned right and saw an object in the sky. I thought at first a plane... looked a little harder and thought hhmmmm don't remember a cell tower being out here.

Got to a stop sign right by the Spooky Nook Golfplex and I sat there staring in the sky at the lights wondering what it was because they were too bright to be a cell tower's lights.

Sat there for a minute or two then the object began moving in my direction. Slowly, too, like 5 mph. Couldn't of been much faster than that at about 200 yards up or so (about the height of a cell tower) as it got closer I took out my cell phone but it's a piece of junk so I couldn't record anything. I cracked the window to see if I could hear anything but there was no sound ZERO noise and this was a large object, too wide to be an airplane.

There were 4 large bright white lights and two blinking lights one blue the other red. It continued to move very slowly and silently across the sky and as it approached the highway it sped up effortlessly to around 50 mph or so.

I just sat there shaking my head trying to figure out what in the hell that could of been! All I know is no known man-made aircraft can move THAT slowly and with no sound across the sky.

Very very bizarre and I wish there was an answer for what that thing was other than U.F.O. I've never seen anything like that and I wasn't on drugs, drunk or hallucinating at the time either!!

I was relieved to hear that other sightings had occurred earlier that day but I haven't seen anything about lights at night.
