Aspect Pattern Scanner

Most aspect patterns are closed circuits between three or more chart bodies connected through aspects. The key word is closed: the same bodies keep feeding one another, so the pattern can become a useful chart-reading structure when its planets are active. Stelliums are the exception here: they are sign concentrations rather than aspect circuits.

Many charts contain at least one supported pattern. A T-Square or Stellium is common. A Grand Sextile is less common and highly settings-dependent. The scanner sorts results rarest first as a browsing aid, not because a rarer pattern automatically matters more.

Each supported pattern is defined by a specific set of relationships. A Yod needs two bodies in sextile and both of them quincunx a third. A Grand Trine needs three accepted trine aspects closing a circuit. The scanner walks your chart's aspect graph and finds each supported configuration that matches.

Golden Yods use the quintile family (72° and 144°), which many standard natal aspect tables skip. The scanner computes those from longitudes so they can be checked. Stelliums use sign occupation rather than aspects, and the scanner catches any sign with three or more eligible bodies.

The scanner runs each supported pattern detector against your chart. It finds Yods (sextile plus two quincunxes), Golden Yods (quintile plus two biquintiles), Grand Trines (three trines), Kites (Grand Trine plus opposing body), Grand Crosses (two oppositions plus four squares), T-Squares (opposition plus apex), Mystic Rectangles (two oppositions plus four supporting aspects), Stelliums (three or more bodies in one sign), plus Cradle and Grand Sextile. Major-aspect patterns use the natal chart service's accepted aspects, whose body-specific orbs are capped at 6°. Quincunxes and fifth-harmonic aspects are added from longitudes before pattern detection.

Eligible bodies are the Sun through Pluto, Chiron, and the Ascendant. Including the Ascendant lets the scanner surface ASC-anchored configurations that planet-only scanners miss. Lunar nodes, Midheaven, IC, and Descendant are not currently included in pattern detection. Results are sorted with rarer patterns first, but tightness, body involvement, and chart context still decide priority.

Running your chart through this scanner and another one and getting different pattern lists is common. Four drivers explain most of the disagreement. Orb settings are first: different tools use different defaults, and the same Grand Trine can appear valid in one and just miss in another. Quincunx and quintile inclusion is second: calculators that skip these aspect families never find Yods or Golden Yods, no matter how close the geometry is.

Angular inclusion is third: patterns involving the Ascendant appear in scanners that treat the ASC as a pattern participant (this one does) and vanish in scanners that do not. Scanners that also include the Midheaven, IC, Descendant, or lunar nodes may flag additional patterns this tool will not. Stellium definition is fourth: some tools require tight conjunctions, others accept any three planets sharing a sign. Pick one convention and stick with it; mixing results from tools with different defaults produces inconsistent readings.

Four priorities help rank which results to inspect first. First, tightness: patterns with all arms under 3° deserve more weight than loose formations. Second, Ascendant involvement can make a pattern more visible in presentation and body. Third, personal-planet content matters because patterns containing Sun, Moon, Mercury, Venus, or Mars are usually easier to connect to daily life. Fourth, repetition matters: patterns that share planets point to bodies doing more than one structural job.

Rarity matters too, but as a tiebreaker rather than a primary filter. A tight common pattern can outweigh a loose rare one. After identifying your priority patterns, open the relevant learn pages for interpretation. If a pattern you expected did not appear, the orb on one of its aspects may sit outside this scanner's accepted aspect set. Run your full birth chart and check the exact orb on each aspect to see whether the pattern is borderline rather than absent.

If the chart feels organized by subtler aspect families, run the harmonic chart calculator next. It is the cleaner follow-up for quintiles, septiles, noviles, and other structures that may not appear as a major aspect pattern in this scanner.
