AstroSignature Forecasts & AstroSignature Research: of aspects to planet nodes, perihelion, and aphelion: In Sirius you can include in AstroSignature research and AstroSignature Forecasts aspects to the geocentric or heliocentric North Node, South Node, Perihelion, and Aphelion of Sun, Moon, Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto.
(Technical note: for Moon this is perigee and apogee rather than aphelion and perihelion, and nodes do not exist for the Sun). These points are used by some astrologers and are now available in these parts of Sirius.
