    Final elset:
    Diamant B r                                      177 x 168 km
    1 04802U 70109B   01356.65800809  .12117115 -27810-4  11173-2 0  6626
    2 04802  14.9929 308.4082 0006604 281.0595  79.0731 16.37512122683982
    
    Note: Although my analysis suggests that this might have decayed
    on a pass over Colombia and Venezuela, the near-circular equatorial
    orbit means that this could have re-entered almost anywhere around
    its final orbit. No elsets were issued during its final five hours
    or more but I predict the following for the start of its final rev:
    Diamant B r                                      149 x 144 km
    1 04802U 70109B   01356.84017104  .44323315  17828+1  90930-3 0 96622
