I take the dog out for his nightly business at 2330hrs. i look up and moving slowly from north to south is an angle shape with dim white lights. at first i thought it might be some kind of spotlight reflecting off the clouds. problem was, there were no clouds. we live close to an airport so my next thought was some kind of plane. problem there, no port/starboard indicators, no sound. it moved slow to the southeast then faded straight up into the sky.
