    Note : for number crunching eyes only ...

    Dear Paul,

    Once again, I keep really enjoying your computation skills.

    Since on my side, I had to tackle and did solve - albeit in a different manner - this same problem (initially for Transits on the Sun disk) I am submitting to NavList in this attachment an algorithm which also derives the time and distance of minimal geocentric distances between 2 moving celestial bodies.

    To the best of my understanding : although both methods are related, this one method here differs somewhat from the one published by Jean Meeus in the early 90's.

    I am not claiming that I am the first one or the only one to have devised this specific one, because it might very well have been published earlier or elsewhere (by whom, when and where ?).

    Best Regards to all,

    Kermit

    What is NavList?

    NavList is a community devoted to the preservation and practice of celestial navigation and other methods of traditional position-finding. We're a group of navigators, navigation enthusiasts and hobbyists, mathematicians and physicists, and historians interested in all aspects of navigation but primarily those techniques which are non-electronic.

    To post a message, if you are already signed up as a NavList member, start a new discussion or reply to any posted message and use your posting code (this is a simple low-security password assigned when you join). You may also join by posting. Your first on-topic messsage automatically makes you a member, and a posting code will be assigned and emailed to you for future posts.

    Uniquely, the NavList message boards also permit full interaction entirely by email. You can optionally receive individual posts or daily digests by email, and any member can post messages by email (bypassing the web site) by sending to our posting address which is "NavList@NavList.net". This functionality is similar to a traditional Internet mailing list: post by email, read by email, reply by email. Most members will prefer the web interface here for posting and replying to messages.

    NavList is more than an online community... more about that another day.
