Study Types

There are 25 study types available, each generating a list of specific astronomical/astrological events. Every event will include at least one date/time and corresponding body position. Here's a brief overview of each study type:

Mundane Studies​

  • Mundane Aspects: Generates an event when a pair of bodies form an aspect with each other.
  • Grand Trines: Generates an event when three bodies form a 120° aspect with each other with none of the bodies conjunct another.
  • T-Squares: Generates an event when two of three bodies are in opposition and the third one is square the other two.
  • Yods: Generates an event when three bodies form two quincunx (150°) aspects to a focal planet, and the two planets forming the quincunx aspects are sextile (60°) to each other.
  • Stelliums: Generates an event when three bodies are conjunct.
  • Mundane Parallels: Generates an event when a pair of bodies form a parallel or contra-parallel aspect to one another.
  • Mundane Stations: Generates an event when a body stations retrograde or direct.
  • Retrograde Cycles: Generates an event when a body stations retrograde. Event data includes the exact times, locations and time periods for the retrograde station, direct station and when the body leaves the shadow zone.
  • Hotspot Transits: Generates an event when a body forms an aspect to a fixed longitudinal degree on the zodiac (hotspot or critical degree).
  • Speed Extrema: Generates an event when a body reaches a maximum or minimum longitudinal speed.
  • Mundane Arcs: Generates an event when a body has traveled a whole number multiple of an interval that is specified in degrees of longitude.
  • Nodal Transits: Generates an event when a body transits its ascending or descending node.
  • Latitude Extrema: Generates an event when a body reaches a minima or maxima in latitude/declination.
  • Solar Eclipses: Generates an event when a solar eclipse occurs.
  • Lunar Eclipses: Generates an event when a lunar eclipse occurs.

Transit Studies​

  • Aspect Activations: Generates an event when a pair of transiting bodies are aspecting each other while at least one of the transiting bodies is conjunct a natal body.
  • Transiting Aspects: Generates an event when a transiting body forms an aspect to natal body.
  • Conjunction Activations: Generates an event when a pair of transiting bodies are conjunct while forming an aspect with a natal body.
  • Grand Trine Activations: Generates an event when three transiting bodies form a Grand Trine with at least one of the transiting bodies conjunct a natal body.
  • T-Square Activations: Generates an event when three transiting bodies form a T-Square with at least one of the transiting bodies conjunct a natal body.
  • Yod Activations: Generates an event when three transiting bodies form a Yod with at least one of the transiting bodies conjunct a natal body.
  • Stellium Activations: Generates an event when three transiting bodies form a Stellium with at least one of the transiting bodies conjunct a natal body.
  • Transiting Parallels: Generates an event when a transiting body forms a parallel or contraparallel aspect to a natal body.
  • Solar Eclipse Activations: Generates an event when a solar eclipse occurs that is aspecting a natal body.
  • Lunar Eclipse Activations: Generates an event when a lunar eclipse occurs that is aspecting a natal body.

These study types allow for a wide variety of event tracking and analysis in both astronomical and astrological contexts.
