The residents of Utqiaġvik, Alaska (formerly known as Barrow), saw the final sunset for 2018 last Sunday. The city is currently in complete darkness until the sun rises on January 23, 2019, which is when residents begin to see touches of light over the horizon again (due to the refraction and scattering of the atmosphere).

Between November 18 and January 23, there is a decreasing amount of twilight each day (see illustration below) during the first half of the polar night, and on the winter solstice (around December 21 or December 22), civil twilight in Utqiagvik lasts for a mere 3 hours. By January 27 or 28, the sun rises completely over the horizon.
