SUNSET:

Sudan has lost the sun below the horizon resulting from the rotation of the earth. The sun will set the west exactly as the spring and autumn equals, each of which only happens once.

The sun is separated from Twilight, which has three stages, the first tower to twelfth, which begins once, when the sun disappears below the horizon, and as long as it reaches 6 degrees below the horizon; the second step is the nuclear Twilight, horizontal is between 6 and 12 degrees; and the third fluorometric twilight, which is when the sun is horizontal between 12 and 18 degrees below.
