At high latitudes in summer, the sun's arc becomes so shallow that it never dips far enough below the
horizon for the sky to stop glowing. Civil twilight requires the sun to be 6° below the horizon. In some
cities it never reaches that threshold, so the sky stays bright all night.
As you move further from the equator, the sun's path across the sky becomes shallower. This means it
takes longer to cross the horizon, extending twilight before sunrise and after sunset.
