    Re: The "Death to the Intercept Method" revisited?

    Hi Tony,
    I'm no expert, but have been using this for some time (pre-programmed on a 
    Casio fx-3650P. I use it to quickly check my sun/moon fixes (using lunars for 
    time) which is my eccentric hobby. )
    You do not need simultaneous H1 and H2 as far as I know. The GHA and H (and I 
    suppose Dec) vary with time anyway.
    I do use "simultaneous" H1 H2 for my moon/sun fixes, but that is because I 
    like to use a lunar generated GMT (no clock method). I then get my 2 Hcs to 
    get my fix.
    The 2 body time sight fix does not need that as far as I can see. 
    Anyway, it seems to work fine with me. Just enter the H1 H2, decs (+N, -S) and 
    GHAs as they are. Should work.
    Hope that is correct. Apologies if I have it wrong.
    No doubt one of the real experts will know.
