Nodal Transits Study

The Nodal Transits Study generates an event whenever a transiting body crosses its ascending or descending node (the points where a body's orbital plane intersects the ecliptic).

Create a Nodal Transits Study

To add a new Nodal Transits Study to the active workspace:

1. Click Mundane Studies on the menu bar.
2. Click Declination Studies, then click Nodal Transits in the submenu.

You can also create a Nodal Transits Study from the toolbar by clicking the Declination Studies drop-down button and selecting Nodal Transits.

Events Captured

A Nodal Transits event occurs when a body crosses its own ascending node (the body moves from south of the ecliptic to north) or descending node (the body moves from north of the ecliptic to south). Both subtypes are reported in a single events table, distinguished by the Event Type column.

Events Table Columns

The events table for a Nodal Transits Study contains the following columns:

Column	Description
Date Time	Date and time of the nodal transit event.
Event Type	Type of nodal transit (e.g., crossing the ecliptic ascending or descending).
Body	Name of the body crossing the node.
Body Longitude	Ecliptic longitude (or right ascension) of the body at the event.
Body Sign	Zodiac sign (with degrees) of the body.
Body Latitude	Ecliptic latitude (or declination) of the body (zero at the node).
Body Distance	Distance of the body from the coordinate origin.
Body Speed	Daily motion of the body.
Event Interval	Time interval since the previous nodal transit event.
