    That is exactly it.  The Sun-satellite-observer angle can make a big 
    difference.  The sunlight reflected off the satellite behaves just like the 
    light reflected from the Moon.  When the Moon (satellite) is between you and 
    the Sun you only see a thin crescent and hence it's not as bright; when 
    you're in between the Sun and Moon the Moon (satellite) is nearly full and 
    hence bright.  The best satellite passes are those that are in the sky 
    opposite the Sun.
