    However, good locations for observing the last passes would be, for the northern hemisphere
    (evening observation), between about latitude +25 N deg and +37 N deg, and for the
    southern hemisphere (morning observations), between about latitude +53 S and 41
    S deg, close to the ground track:

    Anyone hearing of visual passes in the last 6 hours or so?  (There haven't been many opportunities).
    
    Trying to track down at least one observation to re-peg the TLE files.
