    SkyMap can calculate this for you.  However, it is a fairly
    advanced feature that many may have difficulty setting up.
    I will try to put together a configuration file which when
    run shows the tracks of the largest/brightest satellites
    (assuming there are any) that dip into the umbra.

    Exactly the reason I added this feature to SkyMap in time
    for the August 11th eclipse through central Europe last
    summer!

    Very likely not.  I doubt anything with an inclination less
    than 65 degrees has a chance.
    
    Best,
    Rob

    My condolences to any of our French or German friends who
    might have had friends or family on that flight from Paris
    to New York.  Evidently this was a chartered flight of 100
    German tourists and 9 French crew.  At least 4 people on
    the ground (either in or near the hotel that was hit) were
    also lost.
