Interpreting Solar & Lunar Ingresses

(Updated 8/18/16.)

A strategy has evolved for tabulating information we want to assess in interpreting a solar or lunar ingress for a particular location. The interpretation itself is a mixture of science and art, resting first on correctly identifying the operative factors. I recommend the following approach - but, first, some definitions...
"Angular," for this purpose, shall include all foreground planets (within 10° of the meridian or horizon as measured in PV longitude); conjunction or opposition to the Eastpoint (within 3° as measured in Right Ascension); or square the Ascendant (3° by longitude) or Midheaven (2° in longitude; 3° seems excessive in practice).

"Dormant" means that no planet is within 3° of the horizon or meridian (in PV longitude), or 2° (if a single planet) or 3° (if two or more planets together) from the secondary angularities as listed above.

Aspect used are conjunctions, oppositions, and squares. Generally the top effective orb in these ingresses is 3°, though for conjunctions and oppositions this can be stretched closer to 4°. Other than Moon aspects, the only aspects considered are between foreground/angular planets.

1. MOON ASPECTS. Identify conjunctions, oppositions, or squares of Moon to another planet within an orb of 3° (or, for conjunctions and oppositions, as much as 4°). These may be ecliptical or mundane aspects.

2. SCREEN FOR DORMANCY. Based on criteria given above, determine whether the chart is dormant. If so, stop reading it: its predecessor ingress flows through and continues to operate. If the chart is active (non-dormant), continue.

3. ANGULAR PLANETS. Determine which planets are angular. (These, and planets aspecting Moon, are the only planets you will consider in reading the chart.) As discussed previously, a planet is angular if within 10° of the horizon or meridian in Prime Vertical longitude (i.e., in the mundoscope), within 3° of Eastpoint or Westpoint in Right Ascension, within 3° of square Ascendant in celestial longitude, or within 2° of square Mid-heaven in celestial longitude.

4. ASPECTS. Identify conjunctions, oppositions, or squares between angular planets within a 3° orb (for conjunctions and oppositions, up to 4°). Consider ecliptical and mundane aspects equally.

5. MIDPOINTS TO ANGLES. Of the angular planets, identify pairs that are equidistant from angles by checking for midpoints to angles within 1°. Measure these in the same framework as the angularity (Prime Vertical for horizon and meridian, longitude for ecliptical squares to the angles, RA for Eastpoint/Westpoint).

This provides the raw mathematical information on which sound assessment rests. Chapter 6 of SMA gives interpretations for planetary angularity and aspects.
