    This is an excellent naked eye object - I believe that this is the 
    first Centaur in many years to have both apogee and perigee in LEO; I 
    would imagine that as time goes by, the very light Centaur will drop 
    both apogee and perigee, making it a spectacular object. I believe 
    that I noticed a slight copper color, but this may have been an 
    artifact of my knowledge of the color of the insulation covering the 
    upper stage.
    The 7 second "flare" was quite noticeable.
