    In general (very general), the ones that drift to the west 
    (the great majority of drifters) flash some minutes later 
    from one night to the next.  Usually if one flashed a 
    couple of nights ago, it will again.  Right now the rapid 
    southward motion of the Sun (well, the changing tilt of 
    the Earth, of course) means in general that the reflections 
    are moving north from night to night, so that could have 
    some effect, but it depends on the path of the flashes on 
    the ground.  It's all very technical, and I don't get a lot
    of it.  But I know usually within days you can see one that 
    you saw before.  A rough guess is from five to 15 minutes 
    later per night.  But Superbird A is only about a minute 
    later per night.
