    SCC has posted a decay warning for FSW-3 1, but still nothing for SNOE
    or for the Astro 4 rocket, which is closer to decay than either of the
    others. Here is a summary of the updated notices on my Decay Watch page;
    check the page for predicted elsets.

    Note: SCC has yet to post decay warnings for this. It enters eclipse
    southbound near 24 deg S in the evening and leaves eclipse northbound
    near the equator before dawn.

    Note: Although SCC has posted a decay warning for this, this might be
    in line for another manoeuvre which would render the predictions
    invalid. The object enters eclipse while northbound near 35 deg N
    in the evening sky, with eclipse exit southbound near the equator
    before dawn.
