How to use Harmonic explorer

Reveal a natal aspect family by multiplying each selected ecliptic longitude by harmonic number h and wrapping the result into 0–360°. Conjunctions in the transformed chart can reveal separations of 360°/h and its multiples in the source chart. Astrodienst chart documentation

Inputs: Source planetary longitudes in a stated zodiac/frame; harmonic number; planet selection and aspect tolerance. If derived from birth data, retain its time quality. Only include transformed angles when their source time and the method support them.

  1. Choose the source chart and an integer harmonic, such as 5.
  2. Generate the transformed wheel and positions table.
  3. Select a conjunction or pattern and compare it with the natal angular separations.
  4. Read both the harmonic-chart orb and its source-chart equivalent.
  5. Compare another harmonic while retaining the natal chart beside it.
Teaching example · invented coordinates

Planet A at longitude 10° and B at 82° are 72° apart. At h = 5, A becomes 50° and B becomes 410° mod 360° = 50°: an exact conjunction. Change B to 82.2° and its transformed position is 51°, leaving a 1° harmonic-chart orb. That corresponds to a 0.2° natal deviation from 72°. Multiplication method, first-party harmonic dictionary

The fifth harmonic is not automatically the fifth house. A conjunction in h = 4 could derive from a natal conjunction, square or opposition. A harmonic chart is a mathematical transformation, not the sky at another time. A close pattern in a high harmonic is more sensitive to source-position uncertainty. State whether the mode accepts integers only, fractional harmonics or an age-derived value. Default this guide to aspect exploration; interpretation of transformed signs and houses requires a separately named convention. Do not treat a Western h = 9 analysis as interchangeable with a Jyotish Navamsa reading merely because related arithmetic is involved. Preserve the original aspect and any lower-harmonic relationship in the inspector.

Sources and conventions

History & development

Cosmobiology is particularly associated with Reinhold Ebertin's publishing and teaching. The Kosmobiologische Akademie's institutional history records earlier uses of the name and Ebertin's subsequent conferences and publications. Its claimed research orientation is part of the movement's identity, not itself evidence that its interpretations have been scientifically established.

Mythology & symbolic world

Midpoint schools translate planetary combinations into symbolic themes, often using compact descriptions rather than extended mythic narratives. The mathematically named 'cosmogram' remains an astrological representation; it is not a biological measurement.

Provenance: where the rules come from

A midpoint calculation can be shared across schools, while an Ebertin-style combination dictionary requires an explicitly identified edition. This wiki does not infer an entire doctrine from a generic midpoint output.

How it is calculated

Two midpoint branches and custom angular relationships.

Uses & use cases

  • Inspect three-point angular patterns systematically.
  • Compare the same pattern in a full wheel and a reduced dial.

Interpretation methods

Method 1

Midpoint audit

Calculate both opposite midpoint branches, record the original separation, and examine which third points fall within a preselected tolerance.

Study example

For 350° and 10°, the short-arc midpoint is 0°, with the opposite branch at 180°. Ordinary averaging gives the opposite branch, so the branch must be labeled.

Disagreements & limits

  • A dense midpoint list needs a selection rule to avoid choosing only memorable matches.
  • The reviewed institutional history does not independently verify every rule in the school's interpretive handbook.

Sources & evidence

Practitioner sources describe their own systems. Historical and astronomical sources support different kinds of claims. Reading exercises are editorial teaching examples.
