An Idaho witness watched a triangular-shaped object "with a border of lights that seemed to flash" in the night sky on April 15, 2010, according to testimony from the Mutual UFO Network (MUFON) database.

While the border was visible, the witness could not make out the body.

"The center was not lit up and couldn't tell if it was solid or open," the witness stated. "It was so much larger and brighter than anything else in the sky that I noticed it as soon as I began viewing the night sky."

The witness observed the object several times during the evening and commented that it appeared to be 50 times the size of a passing plane.

"This time I noticed an aircraft flying below it and could compare sizes somewhat. The triangular object was much larger, perhaps 50 times larger."

Idaho, April 15, 2010 - Spotted large triangular object in sky. It was bordered with lights that seemed to flash. MUFON Case # 22870.

Standing on the back porch looking at the stars, I noticed a large triangular object with a border of lights that seemed to flash, although it may have been due to the distance.

The center was not lit up and couldn't tell if it was solid or open. It was so much larger and brighter than anything else in the sky that I noticed it as soon as I began viewing the night sky.

I wondered if it was something projected from the ground, but it was much too high in the sky for that. Nor could it be a light projection from the earth to sky. It was located in the upper southwest quadrant. It remained stationary for over 15 minutes.

I returned to the house, but came out an hour later. It was still there. This time I noticed an aircraft flying below it and could compare sizes somewhat. The triangular object was much larger, perhaps 50 times larger. I watched for another 15 minutes. The object remained stationary.

An hour later I returned to look but it was gone. I hoped the triangular object was being viewed by the aircraft and that I might read about it in the newspaper, but it was not. I felt confounded by the object, trying to make sense of it, but could find no explanation for what it might be and concluded that it was a UFO.
