Dictionary term
Refraction Correction
Direct answer
Refraction Correction is the adjustment for Earth's atmosphere bending a celestial ray and raising the body's apparent altitude.
Refraction Correction is an atmospheric bending correction used in historical astronomy, timekeeping, or navigation.

The story behind Refraction Correction
Astronomers and navigators developed refraction tables as increasingly precise observations exposed systematic bending.
Refraction Correction in spiritual tradition
Refraction Correction rewards careful observation, explicit assumptions, and humility about the limits of every model or measurement.
The Great Almanac frames Refraction Correction with educational restraint. Mystical or symbolic language may be meaningful, but it should not be exaggerated into certainty, panic, or permission to ignore ordinary responsibility.
Refraction Correction in the Bible
This is a factual history-of-science, instrument, timekeeping, or navigation reference. It may support wonder and disciplined attention without becoming a claim of fate, worship, or private revelation.
Refraction Correction in numerology
Refraction Correction is not a numerology claim. Any numbers attached to it should retain their ordinary scientific, calendrical, navigational, or historical meaning unless a separate symbolic interpretation is clearly labeled.
Why Refraction Correction matters
Refraction Correction matters because refraction is strongest near the horizon and separates apparent direction from the vacuum geometric direction.
Example in a reading: A low star sight receives a larger refraction correction than a high-altitude sight.
Interpretive caution: Near-horizon refraction is variable and can be anomalous, so a standard table cannot remove every local effect.
How Refraction Correction is used in a reading
Use Refraction Correction by using the altitude range and atmospheric assumptions of the approved table or model.
Where interpretation stops
Refraction Correction is presented as sourced astronomy, calendrical, Earth-science, cultural, or instrument-history reference. Definitions should distinguish measured phenomena from civil convention and historical interpretation, preserve location and time dependencies, and avoid turning factual sky data into a deterministic personal claim.
Sources and editorial method
Research references used for this entry include:
- National Geospatial-Intelligence Agency: The American Practical Navigator - Official modern reference for navigation principles, celestial observations, sight reduction, and navigational tables.
- U.S. Naval Observatory: Astronomical and Navigational Almanacs - Official descriptions of the Astronomical Almanac, Nautical Almanac, and their tabular data.
The page starts with a direct definition, then separates use, example, caution, spiritual meaning, and historical context. For astrology, occult, demonology, curse, and spiritual warfare terms, the editorial rule is to explain the term without making fear-based, fatalistic, medical, legal, financial, or ritual-instruction claims.
