    Note: The final elset has a too-low drag term and some of the recent
    perigee heights are suspect. I have this decaying over Tanzania on the
    following SatEvo-predicted rev:
    Atlantic Bird 2 Ariane 44P r                     547 x 89 km
    1 26928U 01042B   02223.59635397 2.83204287  62440+1  18344-2 0 93908
    2 26928   7.2716 313.5784 0341986 246.4714 109.8991 15.84571349  9656
    A decay one orbit earlier or later cannot be ruled out.
