Opposition Aspect
The 180-degree axis, alternation, and negotiated awareness. This guide gives a reproducible rule, worked example, illustrative near miss, and explicit limits.
Overview
An opposition centers on 180° and places two factors across an axis, inviting comparison, alternation, projection, or negotiated awareness. The page separates calculation from interpretation and keeps this worked result conditional: separation 178° establishes a 2°-orb opposition; the decision log tests how the axis is lived without assigning either pole to another person. Verification follows this declared method: Compare 3° Aries with 1° Libra, calculate 178°, record a 2° orb, then identify both ends of the axis without assigning one to another person automatically.

Definition and exact scope
an opposition centers on 180° and places two factors across an axis, inviting comparison, alternation, projection, or negotiated awareness
Calculation or decision rule
compare 3° Aries with 1° Libra, calculate 178°, record a 2° orb, then identify both ends of the axis without assigning one to another person automatically
Worked case and illustrative near miss
♀ 3°♈ and ♂ 1°♎; exact target 180°; orb cap 7°; a six-week decision log distinguishes alternating initiative from negotiated turn-taking. separation 178° establishes a 2°-orb opposition; the decision log tests how the axis is lived without assigning either pole to another person.
Illustrative near miss: Assigning Libra to a partner and Aries to the native without directional evidence turns a measured axis into projection and erases possible alternation.
School and variant boundary
Exact angles are geometry; orb choices, priority, and symbolic language are declared practitioner conventions.
Product, safety, and verification boundary
OpenFate can connect Opposition Aspect to the natal chart and reading flow where supported; the connection supplies evidence, not a guaranteed life result. Verification retains failed measurements and uncertainty, then revises interpretation rather than the receipt. Opposition Aspect cannot diagnose a person, remove consent, or guarantee an event.
