    Hi Roger,

    But these can't be PERFECTLY accurate because the shadow's size varies slightly from one eclipse to another, for unknown reasons.

    That's interesting.  If both shadow-ingress and shadow-egress observations are available, then taking the mean should remove this bias.

    Visual photometry is one thing, but I've wondered how well eclipses of Jupiter's moons could be timed with, say, webcam photometry.  The same question would apply to lunar craters I guess.

    Cheers,
    Peter
