    SpaceCom has posted the first decay notice for #26625, the Anik F1 
    Ariane 44L rocket. I have updated my Decay Watch page for this and for 
    two other interesting decayers, NASA's EUVE satellite and the tumbling 
    Iridium 27. Here is a summary of the page:

    and leaves eclipse while northbound near 13 deg S before dawn.
