The scientific name for Midnight Sun is Polar Day, the opposite is Polar Night. As the upper edge of the solar disc disappears below the horizon the Sun has set, and there's no longer Midnight Sun. The moment the solar disc again becomes visible above the horizon, it's sunrise.ne of the reasons that the Midnight Sun doesn't end directly on the polar circle, but can be seen a little south as well, is refraction; The fact that light bends when it hits the Earth's atmosphere. Refraction makes the Sun visible above the horizon several minutes before it actually gets there.
