    | Is there any way to predict when the orbital plane of USA193 is over

    might give me an excuse to get out of the house...
    
    I've been working on a tool for a while now, mostly delayed due to last
    year's clouds over Texas for almost half the year. It doesn't tell you
    when you'll be able to see something like Heaven's Above does, but it
    will tell you how to point a telescope to follow an orbital plane as it
    comes up and sets.
    
    It's still rough. It doesn't do atmospheric correction, and everything
    is in Alt/Az (no RA/Dec yet). Also, it's on a very slow link and can
    make in excess of 400K of output at a go:

    I've only got a handful of IDs in the system at the moment. All of Mike
    McCants' daily updates are in there, but not on the list link, so you'll
    have to know what vehicle ID you're after.
