    OIG/SPACECOM exchanged the labelling of Iridium 11 and Iridium 20 on
    January 29, 2004.
    This does not mean any change in the Iridium constellation.
    The object being tracked under catalog number 25577 remains part of the
    active constellation, but is now known as "Iridium 20" rather than
    "Iridium 11", while the object with catalog number 25578 remains spare in
    a lower orbit, but is now known as "Iridium 11" rather than "Iridium 20".
    This addresses a long-standing mislabelling of these objects. It would
    appear that these objects got interchanged by Spacecom at some stage
    before one of the satellites (known to the operators of the Iridium system
    as "Iridium 20") was raised to operational altitude in 1999.
