I went out on my back porch at 1912hrs and was looking up at the night sky (very clear skies and approx 58 degrees) when i saw a very bright object that was about the same size and 70-80% as bright as saturn. i live about 11 miles from downtown jacksonville so light pollution allows for only the brightest stars to be visible. it originally caught my eye because it was the brightest visible object, next to saturn, in the sky at that time. the other reason it got my attention was the speed it was traveling. it was moving about as fast as you would expect an airliner to cross the sky but i saw no external lights i.E. anti collision lights, strobes, red and green wingtip positional lights… just a bright point of light. i first saw it northwest of my house heading southeast and went almost directly overhead so i saw it "coming and going" and the point of light never changed brightness like you would see on an aircraft if you were to see the nose (landing light), and as it passed, see the dimmer the tail light. it stayed the same level of brightness the entire duration of the event. from my perspective it passed about 10° to the east of orion's belt. i live approx 6 miles due east of jacksonville naval air station and see a lot of military aircraft and this was not an aircraft. i also was an army aviator, flying uh-1's and oh-58's (a and c models).I attempted to take a picture and video with my iphone 4s but the distance and size of the point of light wouldn't allow my phone to capture anything.
