    SpaceCom has added a second 1970's rocket to the list of objects for
    which decay notices are being posted. I have updated my Decay watch page
    for the following ...
    _____________________________________________________________________
    Object: #4392 = 70- 34 B = Mao 1 Long March 1 rocket

    Note: The latest elset shows this running 10 sec late against my
    previous prediction. I show this decay slipping further into the 29th
    when it may re-enter southbound over the SE Pacific. There are some
    transits across the USA on earlier revs
