    I'm not aware that colour can be used to differentiate between satellite
    reentries and meteors, either the object itself or its train. Meteoric
    fireballs are much more numerous than reentries and come in all colours.
    Indeed personal perception plays a role, too, with the same object being
    described as different colours by different observers.

    Sorry, I don't have sufficient records/elsets for this period. I'd hoped
    someone else might come forward on this one. You don't quote a duration
    for the event which, remember, is an important indicator of a satellite
    vs a meteor.
