Nocturnal Hemisphere
From Astrowiki-en
The hemisphere of the horoscope below the Ascendant/Descendant axis in a standard graphic depiction of a horoscope. The nocturnal hemisphere contains the first six houses and the first and second quadrants and its central point is the Imum Coeli.
The nocturnal hemisphere is considered to be the more introverted hemisphere of the horoscope. Signs and planets in this hemisphere reveal an individual's more inner or unconscious qualities. Its counterpart is the diurnal hemisphere of the horoscope.
The Ascendant/Descendant axis divides the horoscope into a diurnal and nocturnal hemisphere.
