    Subject: Lower branch transits of moon?

    > Why does the Nautical Almanac include data for lower branch moon transit?

    Take a look on page 153... (and all odd pages until 253) right down !

    Lat = 180° - (Zd + d)

    Zd= zenithal distance, 90° - alt.
    d = déclination of the moon at time of lower transit.
