    1998-051D (#25470) Iridium 79
    
    SPACECOM'S FINAL REPORT shows the decay on
                     29 November, 09:36 UTC +/- 38 minutes (27.5°N, 80.3°E)
    on an ascending pass over northern India.
    My preceding prediction delivered 
                     29 November, 09:45 UTC +/-07 minutes (69.95°N, 86.65°E)
    on the same pass over northern Sibiria.
    My calculations based on a predicted geomagnetic activity parameter (Ap) of
    025. The actual value for Nov 29 released today was 050 ! and caused as one can 
    expect an earlier decay. MPM + REENTRY shows now             
                    29 November, 09:38 UTC +/- 07 minutes (40.92°N, 80.81°E) 
    on the same pass over Central Asia.
