The Twilight is the effect produced by the illumination of the Earth’s lower atmosphere when the Sun itself is not directly visible because it is below the horizon so it happens before sunrise and after sunset.  There are multiple classifications: civil, nautical and astronomical and all of them differ by the angle of the geometric centre of the sun in respect of the horizon.
