    Howdy SeeSatters!
    Here's a silly question.
    If one had a good view of the terrain around them (e.g. from a high 
    point), and if the actual dead center ground track of an Iridium 
    reflection passed very close nearby, could one literally see a bright 
    spot moving across the ground?
    I realize we're talking about a FAST moving reflection!  If, for 
    example, I could see about five miles of ground track at one time 
    from my high perch, I figure it would traverse from one end to the 
    other in about one second, but that seems to me to be perceptible.
    Just how illuminated is the ground from a -8 flare?  Does anyone know 
    if there's a concentrated spot of light right down the track?  How 
    big would the spot be?
    Like I said - a silly question?
