    Here is another summary from my updated Decay Watch page, now including 
    the first notice for the Progress M-47 rocket.

    Note: While there is a chance that this might survive into the final
    SatEvo-predicted rev, above, I favour a decay following perigee on
    the penultimate orbit. This puts it southbound over the S Atlantic.

    Note: I have this decaying southbound over the Democratic Republic of
    the Congo, Africa, on the orbit given by the final elset, above.

    Note: It is very odd that the latest elset for this is 14 hours old.
    I have this decaying following the southbound equator crossing in
    the orbit given by my final predicted elset above. This puts it over
    the western Pacific.
