I don't recall this being discussed in the
past on Navlist but we have discussed the similar method of getting a
star fix and then adjusting the assumed time to make a moon line pass
through the star fix. This method will provide a longitude and GMT
(which is better than nothing and may be good enough) but the objection
was that the precision of the derived GMT/ longitude suffers due to
observational errors and also due to the slow change in the position of
the Moon. This method would suffer from some of these same
problems and would lack the accuracy of the traditional Lunar but also
may be "good enough." gl --- On Sun, 5/6/12, Alexandre E Eremenko <eremenko@math.purdue.edu> wrote:
