The case backwards, which has been stated to be the most frequent, is facilitated by the direction of the convex articular surfaces of the scaphoid, lunar, and cuneiform bones, which slope more backwards than forwards.]

* (nautical, navigation) An observation of a lunar distance (“the angle between the Moon and another celestial body”), especially for establishing the longitude of a ship at sea.
** 1859 October, Henry Toynbee, “A Few More Words on Lunars”, in The Nautical Magazine and Naval Chronicle: A Journal of Papers on Subjects Connected with Maritime Affairs, volume XXVIII, number 10, London: Simpkin, Marshall and Co. […]; and J. D. Potter, […], →OCLC, page 511:[Y]oung beginners cannot be too often cautioned that a single lunar is of little or no value until the observer knows the usual difference between his lunars taken on opposite sides of the moon; and these should be taken with the same instrument, using the same screens and telescope, for he must remember that they may be expected to differ. My star lunars differ from three to four minutes, or say fifty miles of longitude; my sun lunars from one to two minutes, or say twenty minutes of longitude.
** 2007, John Karl, “Lunar Distance Sights”, in Celestial Navigation in the GPS Age, Arcata, Calif.: Paradise Cay Publications; Wichita, Kan.: Celestaire, →ISBN, pages 96–97:With cheap quartz watches (several, for reliability) we can do all the modern celestial navigation we could want. But learning and practicing lunars gives us deeper insight into celestial navigation; an appreciation for their historical importance and difficulty; and perhaps most significant of all, after conquering lunars we can appreciate the great convenience of St. Hilaire sights and modern quartz watches. Moreover, in the rare event of losing UT, with lunars and only a poor watch we can still be confident of finding our longitude at sea (well, OK, to within 30′).
