    Re: A Jupiter lunar etc.

    Peter, you wrote:
    " To my surprise both the calculated and measured lunar distance came to 14d 05.1'! (See the two yellow cells in the attached screen capture and their gray companions just below.) Definitely fortuitous, nevertheless pleasant to see, so I figured I'd share this with NavList. :-)"

    These things do happen sometimes! :)

    If you want to get some more interest from that set of observations, you might want to try varying the altitude of Jupiter OR the Moon by, let's say, 6' to see what happens to the cleared results. Then try varying BOTH altitudes by 6' and check again.

    In my experience with Davis plastic sextants, I expect a typical standard deviation (for lunars) of about two to three minutes of arc. But that doesn't mean you won't get lucky again... ;)
