It was a glowing, dull yellow/green, silent, three dimensional horizontal triangle. with verticle cylinders on the end.One object sited passing inderectly over my house, heading north/north east slowly and at an extremely low elevation. I viewed it from my back patio as it passed over. The time was right about midnight. My best guess would be that it was atleast two or three hundred feet in elevation. It's shape, as near as I can explain it, was a three dimensional horizontal triangular shape which ended in vertical cylinders in a wide U shape. The entire object glowed a dull greenish/yellow with no flashing lights, and moved rather slowly. I didn't see any "exhaust trail" or anything indicating an engine exhaust at all. I discounted it's being a blimp, since I never heard any noise from the object. The object maintained it's speed, elevation, and direction for as long as I was able to view it.
