Mundane Parallels Study
The Mundane Parallels Study generates an event whenever a pair of transiting bodies form a parallel or contraparallel aspect. A parallel occurs when two bodies share the same declination on the same side of the celestial equator; a contraparallel occurs when they share the same declination magnitude on opposite sides.
Balanced Parallels Study
The Balanced Parallels Study generates an event whenever two transiting bodies are exactly parallel while being equally distant (within orb) from the 90° axis on the zodiac, on opposite sides of the 90°-270° axis. Use the study to find moments of declinational symmetry around the cardinal axes.
Midpoint Parallels Study
The Midpoint Parallels Study generates an event whenever two transiting bodies are precisely parallel or contraparallel and the near midpoint of their longitudes is conjunct (within orb) a third transiting body. The study identifies declinational sympathies that are activated by an arriving body.
