    Re: Working a lunar. was: lunar distance in Wikiped ia

    George and other doubters,

    I'm sorry to say that my most recent Lunar effort came out to withing 4-minutes of Longitude on the first working. As I intimated in my post, this degree of accuracy is rather astounding and I am going over all my figures to search out any flukes before posting the numbers.

    George, you are well aware that this is not my first effort, as previous posts have spoken of much earlier efforts, before the publishing of distances, at least to my knowledge, and the advent of the internet, when I found it necessary to calculate the true distances for the time frames involved and based on almanac data available.

    My real concern is, that should the accuracy attained in this latest effort be repeatable, then the Lunar Distance might well, as far as I am concerned at least, become a viable tool for use in emergency situations necessitating a recourse to celestial navigation in cases where accurate time be not available. This was my original intent in beginning work on Lunars in the 1940's and early 50's, but as, again to my state of knowledge at the time, there were no readily available tabulations of Lunar Distance against GMT, discontinued my efforts due to the amount of calculation necessary.

    Again regards to all,

    Henry
