    Note: Neither SCC's final analysis nor any further elsets have appeared.
    I show it decaying over the Atlantic following the northbound equator
    crossing at the end of this SatEvo-predicted orbit:

    Note: The final elset was very slow to appear but allows my
    re-estimate of the decay with reduced uncertainty. I now put the
    decay near a northbound equator crossing over the western Pacific,
    in good agreement with SCC's estimate. This comes at the end of the
    the following SatEvo-predicted rev:
    DRTS r Fairng1   3.0  3.0  0.0  3.5 v   10       170 x 167 km
