    Is there any web almanac for  them, to
    practice in longitude from Jupiter satellites?
    (I imagine that  timing their ocultation will be hard
    with my 10x50 binocular, but I would  try)."
    
    [this time for the list] There is a great little Javascript  calculator on
    skyandtelescope.com that displays the current positions of the  moons and
    upcoming occultations and other events. It's very nice. Go  here:

    By  the way, you need much higher magnification to see occultations. That me
    ans a  long focal length telescope which is why the method was found to be
    impractical  at sea.
