Mundane Arcs Study
The Mundane Arcs Study generates an event whenever a transiting body has traveled a whole-number multiple of an arc value listed in the Arcs table. Use the study to track multiple-of-X-degree progressions for any body and arc length you choose.

To add a new Mundane Arcs Study to the active workspace:
- Click Mundane Studies on the menu bar.
- Click Longitudinal Studies, then click Mundane Arcs in the submenu.
You can also create a Mundane Arcs Study from the toolbar by clicking the Arc Studies drop-down button and selecting Mundane Arcs.
Events Captured
A Mundane Arcs event occurs when a transiting body's longitudinal travel reaches a whole-number multiple of an arc value defined in the Arcs table. Each arc value is a degree count; the study reports the moment the body has traversed each multiple of that arc.
Events Table Columns
The events table for a Mundane Arcs Study contains the following columns:
| Column | Description |
|---|---|
| Date Time | Date and time of the arc event. |
| Body | Name of the body crossing an arc multiple. |
| 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. |
| Body Distance | Distance of the body from the coordinate origin. |
| Body Speed | Daily motion of the body. |
| Arc | The arc value (subdivision in degrees) being crossed. |
| Factor | The numeric factor associated with the arc (cycle divisor). |
| Arc Multiple | The multiple of the arc reached (e.g., 1st, 2nd, 3rd multiple). |
| Event Interval | Time interval since the previous arc event. |
