Twilight Phases in Surabaya
The sun times table above shows three twilight phases for Surabaya, each corresponding to how far the Sun is below the horizon:
- Civil twilight (0–6°) — Bright enough for most outdoor activities without artificial light. The horizon is clearly defined.
- Nautical twilight (6–12°) — The horizon is faintly visible. Named for sailors who used this light level to navigate by the stars.
- Astronomical twilight (12–18°) — The sky appears dark to casual observers. Faint stars and galaxies become visible for astronomers.
The daylight bar visualization uses graduated shading to show how these twilight phases transition from full darkness to daylight throughout the day.
