My wife and i were outside smoking,when we saw the object. we have seen this on more than one night. it appears to be navigation lights of standard aircraft (solid white light with blinking red and green), but with no discernable movement. it will hover in the same spot, possibly several miles due west of elsberry, missouri, sometimes disappearing,other times moving off slowly to the south. i observed the object through binoculars, and though i couldn't see a shape,it didn't appear to be a star. google sky map didn't show any high magnitude celestial objects in that position. i don't know if it was a conventional aircraft or not, but i can't see why anyone would hover a helicopter in the same spot for so long at night.
