    John Stetson got a great pic of the ISS passing very close to a sunspot:

    Evidently calsky now shows current sunspots when you ask for sun crosser 
    predictions for the ISS.  I don't know how accurate calsky is but imagine having 
    to move only about 300 feet north or south to get a sunspot eclipse.  I don't 
    think TLEs are that accurate.
