# Analemma Desk Field Notes

Analemma Desk uses a compact solar-geometry model to turn each day of 2026 into a visible point: equation of time on one axis, local solar-noon altitude on another, with daylight duration and low-sun hours as supporting measures.

The reference latitudes are city-named bands rather than site surveys. Longitude, time zones, terrain, refraction detail, weather, and legal sunrise definitions are intentionally out of scope.

## Observations

- Largest daylight swing: Reykjavik band at 16.971 hours between shortest and longest day.
- Most accumulated low-sun daylight: Reykjavik band at 1492.162 model-hours across the year.
- Most even daylight band: Singapore band with only 0.15 hours of annual daylight swing.
- Equation-of-time drift spans 30.636 minutes in this model, enough to bend every latitude trace into the familiar uneven figure-eight.

## Reading The Curves

A vertical move on the main plot is seasonal solar height. A horizontal move is the difference between mean clock noon and apparent solar noon, expressed without longitude or time-zone corrections. The equatorial band has a small daylight swing but a tall noon-altitude loop; high-latitude bands flatten toward the horizon in winter and stretch into long summer light.

## Verification Notes

The run-specific verifier checks generated row counts, daylight bounds, summary consistency, publishable manifest paths, and the presence of the interactive data bundle in the HTML artifact.
