Large red-orange disc moving at steady speed on 5/20.At 23:30, moon was full. Two witnesses observing the full moon noticed a large (1cm at arm's length) deep orange-red circle moving slowly and steadily from 270 degrees to 90 degrees. The lights did not modulate, fade, change or blink. The object was larger than an aircraft.No noise was noted. This was in a rural area and noise pollution is minimal; visibility is quite good. The object did not deviate from its course, change speed, appear to move closer or farther away.The transit of the object was too slow to match a typical satellite, was in the wrong part of the sky for solar reflection and was a color that witnesses have not seen on aircraft, meteorites, satellites or any other common phenomena. The object took no less than 3 minutes to transit 90 degrees of the sky.((NUFORC Note: Witness elects to remain totally anonymous; provides no contact information. PD))
