    Re: Error in taking lunar distance
    From: George Huxtable

    My recent message needs a correction. When I wrote-
    "For the rest of the month, Sun-lunars are available, and indeed preferred
    many observers", that was wrong.
    For a period of about 10 days in each month, around Full Moon, the Sun-Moon
    lunar distance exceeds 120 degrees, putting it outside the range of a
    sextant. During that period a navigator has no option but to use night-time
    star-Moon distances, if he needs a lunar distance.
    So all told, star lunars are quite a lot more available that Sun lunars, and
    a navigator who restricts himself to daytime lunar distances to the Sun has
    much fewer opportunities to get his longitude.
