    I have updated my Decay Watch page with the final notice for yesterday's 
    decay of Iridium 9.

    Final elset:
    Iridium 9 tum    4.0  1.8  0.0  6.5 d   10       153 x 145 km
    1 24838U 97030C   03070.00432100  .30640144 -10971-5  67398-3 0  3204
    2 24838  86.4222 315.2893 0006442 225.1811 135.0798 16.46418872308010
    
    Note: The final elset shows this running 2.4 sec late against my
    previous prediction. I estimate that this decayed northbound to
    the west of North Korea on the orbit after this. It is possible,
    though, that it survived to decay near the next southbound equator
    crossing over north-western Brazil in line with SCC's analysis.
