    We have a new decayer as the Molniya 1T Platform moves begins its final 
    few revs. The following is adapted from my updated Decay Watch page.

    with eclipse exit northbound close to the equator before dawn.

    Note: I estimate that this will decay southbound over SW China
    on the last of these SatEvo-predicted revs. That orbit takes it
    eastwards across N Europe from Shetland at 20:12 UTC.
