Approx 9:00 PM or 21:00 hours. Clear evening, no clouds, temps in the mid 30's. Went out to have a smoke and noticed a movement to my right peripheral side vision in the star filled sky. Saw what appeared as a fuzzy outline of a V formation or triangle craft directly above. Hard to discern it as it appeared slightly lighter then the dark background sky, fuzzy edges with a translucent appearance. Very difficult to see unless looking right at it. No lights, no sound and its glide path was to the South SE. Watched it for 5-6 seconds before it faded from view. Speed looked like around 200 MPH at say 3000 feet altitude, just a guess thou as I could not tell it's size. When first overhead it would have been the size of my hand at arms length. Object did not reflect from the moon that evening and for a lack of better words, appeared to cloak it's self somehow to the background. Very strange. I had my cell phone out however there was not enough time to capture it as I was wondering what it was in the first place. I am knowledgeable in earth sciences,known aircraft and consider myself an amateur astronomer. It matched the dark sky so much, I doubt a photo would have shown it unless during the day. Again this object flew silently down/above main street in a city of 40,000 + citizens and no one else saw it? Another UFO sighting page shows the same object about 20 Minutes before in the community of Ames,approx 70 miles away on the same evening. This at least gives my report a little more substance. Thank You.
