    At 1840-1845 Ut December 16, I had my first chance to observe ISS
    since the new solar cell array had been added. It was a nearly
    overhead ( 86 degrees) pass in the morning twilight( 20 minutes after
    beginning of Nautical twilight), clear sky,
    numerous bright stars for comparison ( Sirius, Canopus, Alpha Cen,
    Rigel, Betelguese and Alpha Centauri). 
    I reckon at is brightest,(60 degrees elevation in the NW)
    it was distinctly brighter than
    Sirius, so my estimate  magnitude is -2. At zenith and as it moved into the 
    bright sky in the SE, it was orange. It was my distinct impression
    that this colour was less prominent near maximum brightness in the NW,
    which is probably what one expects looking at the underside of the solar
    cell array.
