    Coincidentally just before I read Bjorn's message I was in the process of 
    doing exactly that using the time and coordinates given.
    
    34839 Yaogan 6 is the closest candidate though about three minutes out.
    
    If he had stayed there a few minutes longer he might have picked up a couple 
    of other nice transits!
