House Ingresses Study
A transit entering a new house shifts the area of life it acts on, and a House Ingresses study gives you those crossing dates for whichever house system you work in.
The study generates an event each time a transiting body crosses a natal house cusp. Every event records the transiting body, the cusp it crossed, the house it entered and the moment of the crossing.
Create a House Ingresses Study
To add a House Ingresses study to the current workspace:
- Click Transit Studies → House Ingresses on the menu bar.
Alternatively, click the Ingress Studies drop-down button on the toolbar and select House Ingresses from its flyout.
The new study appears at the bottom of the Studies list and is selected automatically, so its settings open immediately. It takes its name from the study type.
What This Study Finds
House Ingresses is a transiting study rather than an activation study, and the distinction decides what counts as an event. The cusps the transiting bodies are watched against belong to the natal record you select, so the natal record is what defines the event: without one there are no cusps to cross. An activation study, by contrast, looks for an event that transiting bodies form among themselves in the sky while one of them is in contact with a natal body.
Because a cusp crossing is an exact moment rather than an approach, the study carries no orb of its own. What it does need is a house system, since different systems place the cusps differently and therefore produce different crossing dates from the same natal record.
The settings column carries a single tab control with an Ephemeris tab, holding the shared ephemeris settings panel, and a Natal Data tab holding the natal record fields and this study's House System drop-down. Beneath the tabs sits the Transiting Bodies selection list.
Choose the House System
The house system states how the natal positions are divided into houses, and so which cusps the study reports crossings of. The drop-down is available while the study is unlocked. The cusps themselves are derived from the natal record on the Natal Data tab, so the system you select only produces events once a record has been selected there.
To choose the house system:
- Click the Natal Data tab in the study's settings tab control.
- Select a system from the House System drop-down.
The drop-down offers twelve systems, listed alphabetically by name:
- Alcabitus
- Campanus
- Equal (Ascendant)
- Koch
- Meridian (Axial Rotation)
- Morinus
- Placidus
- Porphyry
- Regiomontanus
- Topocentric (Polich/Page)
- Vehlow Equal
- Whole Sign
Events Table Columns
The events table shows the columns below. Several columns are hidden by default, as the table notes. Right-click any column header to show or hide a column, as described in Choose Events Table Columns. The headers of the coordinate columns follow the study's Reference Plane: they read Longitude and Latitude in the ecliptic plane, and Right Asc and Declination in the equatorial plane. The ecliptic-plane header text is listed here.
