Dusk in Ulan Bator, stage by stage

Nautical dusk follows at 12 degrees, when the sea horizon disappears, and astronomical dusk at 18 degrees, after which the sky is fully dark and the faintest stars appear. How long dusk lasts depends on Ulan Bator's latitude: near the equator night falls fast, while at high latitudes dusk can stretch for hours or, in high summer, never fully darken.
