    We were clouded out for the first two passes of the STS-113 and
    ISS here in Edmonton. Just after the 6:35 p.m. pass the sky
    cleared and  I realised that the pass at 8:10 p.m. would be
    visible as it gained elevation in the west. I used buildings in
    Guide8's "Horizon Objects" to locate the azimuth exactly.
    
    So with Binos in hand I waited and at the expected time the ISS
    and then the Shuttle became visible. The fainter shuttle was situated
    just to the lower right only a couple of degrees away. They got up to
    about 8 elevation before fading as they entered the Earth's
    shadow.
    Was I  mistaken as  I  thought the brighter object
    (ISS) was the upper one of the two with the Shuttle following,
    but the ISS should be trailing in its higher slower orbit. Maybe
    perspective at that low altitude would reverse the appearance???
    Or had STS 113 maintained a higher orbit.?
    I would have liked to see the earlier pass, darn.
