A dermatologist may excise a suspicious skin lesion from a patientâs ear for a pathologistâs review. The procedure code depends on the definitive diagnosis.

Best Answer: Sunset - the time the sun sets. Dusk - the minutes immediately after the sun sets. Twilight - the fading light of day - usually around 8 minutes as this is the time it takes for light to travel from the sun to earth.
There are three kinds of twilight defined: civil twilight, nautical twilight, and astronomical twilight. For computational purposes, civil twilight begins before sunrise and ends after sunset when the geometric zenith distance of the center of the Sun is 96 degrees - 6 degrees below a horizontal plane. The corresponding solar zenith distances for nautical and astronomical twilight are 102 and 108 degrees, respectively.
