    "... In order to see a satellite go from bright to dim (or invisible) to
    bright again, you need to be in one of two places:  along the path of
    totality, or within about a thousand mile semi-circle radius of the start or
    end point of an eclipse."
    
    Hi Rob,
    
    I hadn't considered the latter case- in any event, for the next total
    eclipse, it looks like only satellites in polar orbit will get to play:

    Antartica, and less than a month before the solstice!
