    to the best of my knowledge there are a few programs available and a website 
    or two which can handle this problem. I use my very own program, SatCal, 
    which apart from transits does a few other useful things like flare 
    calculations and launch orbits. It's Open Source Freeware and identical 
    versions exist for Windows and Linux. I still have to put it properly on a 
    website for download (only a fairly ancient version - Windows exe only - 
    exists on www.aaw-darmstadt.de/download) but I'm happy to e-mail the latest 
    version to whoever is interested.
    
    Of course - no matter what program you use - you have to get into the habit of 
    regularly checking  for such transits. I have caught myself often enough to 
    ignore it for months at a time until all of a sudden I seem to remember these 
    kind of observations!
