Birth Moment · calculated astronomy
The texture of your moment.
Local light at Ruston, plus the Moon’s distance and the planets’ apparent motion as viewed from Earth’s centre.
Sun centre above horizon
Sun 34.4° above the geometric horizon.
A calculated light band, not a visibility or weather report.

How we build this layer · birth-context-v1
Uses the Sun’s centre and an airless, level geometric horizon. Bands are split at 0°, −6°, −12° and −18°; 0° is not the observed sunrise or sunset boundary. Weather, refraction, terrain and sky brightness are not assessed.
Distance is between the centres of Earth and Moon. Approaching/receding uses a centred one-hour distance sample. “Nearly steady” means under 1 km/day in that sample, not a confirmed perigee or apogee. Phase times are calculated events, not predictions about a person.
Retrograde is apparent motion in geocentric ecliptic longitude. The existing chart’s turning flag compares the preceding and following 12 hours. Planets do not physically reverse their orbits; these flags do not imply effects on people.
Light selects the first prompt; lunar distance direction selects the second; an apparent turn, otherwise retrograde presence, otherwise direct motion selects the third. This creative rule never changes your constellation placements.
