    Note: The latest elset shows this running 103 sec early against my 
    final pre-decay prediction. I estimate that decay was most likely near 
    perigee on the rev described by the final elset above. However, it 
    remains possible that it survived to decay near perigee on the next
    orbit, at 01:44 UTC near 56.8S/173.0W (close to SpaceCom's decay 
    point). Both decay points lie over the southern Pacific. My 
    SatEvo-predicted elset for this later rev is:
    Molniya 3-26                                     534 x 63 km
