Nocturnal means of or belonging to the night. In classical astrology, particular planets were classified as nocturnal or diurnal, no matter where they were in a horoscope. In contemporary astrology, planets are nocturnal if they are located below the horizon (in houses one through six). Many astrologers believe that planets above the horizon line show their influence more in the public sphere whereas planets below the horizon are more private, but this distinction clearly breaks down when considering planets in such locations as the twelfth house (a largely private house situated above the horizon). The expression nocturnal arc refers to the distance, expressed in degrees and minutes of a circle, that a planet traverses between its setting in the west and its rising in the east. Classical astrology also classified signs as diurnal (the masculine signs) and nocturnal (the feminine signs). Contemporary astrologers no longer use the expression nocturnal sign.
