Silent huge dark blob blending in with the night sky.I was going for an early morning walk; this time is my favorite for star gazing. I often see many different varieties of ufos whenever I take a moment to look up at the night sky. This instance was the most unusual sighting. The sky was clear except for the residual chem trail mist, pre-sunrise, still dark,the stars were fairly bright. Out of the corner of my eye I saw movement, I focused on it slowly moving from north to south west. It was like a dark blob/oval-ish...the weirdest thing, and the only way I could tell it was up there was how the edges kind of fluttered. They gave the appearance of pixels all around the edges. I said, "What the hell is that?" It hovered a few seconds about 200 feet up, and then continued southwest. No sound. Very very big. No lights. Just the "pixel blending" effect on the edges allowed it to be seen at all. Kind of like when the cable signal is bad..but it blended itself completely into the background. It was very hard to describe, as I have never seen anything like that...
