#ARCTIC. #SIBERIA. THIS IS TAIMYR. Today, at the latitude of Norilsk, the polar night has come, which will last until January 13, according to the generally accepted diagram drawn up by Nikolay Urvantsev. The last daylight hours in Norilsk this year were observed on November 29 – its duration was only half an hour: the sun peeped out over the horizon from 12.32 to 13.02.
The polar night is a consequence of the Earth slope to the plane of the ecliptic, which is approximately 23.5 degrees. It is noteworthy that the polar night does not necessarily mean complete darkness during the day – the main feature is that the sun does not rise above the horizon.
Most of all polar nights on the planet are observed by Russia residents. In open sources it is noted that more than two million people remain without sunlight – this is more than half of all those who live in the Arctic Circle in the world.
The polar night often turns into drowsiness for Norilsk residents. Doctors recommend eating more vegetables and fruits, as well as vitamins A and D. Also, northerners are advised to increase the brightness of lighting in apartments, observe the daily routine and go to bed no later than 11 pm.
By the way, experts have been discussing the date of the beginning of the polar night for many years. Last year, we told that, according to the former teacher of physics and astronomy Alexander Vasyanovich, the polar night in Norilsk begins on December 2 and ends on January 11.
As a reminder, from January 13 to March 27 the Norilsk residents will observe the change of day and night. Then twilight nights will begin at our latitude (30 days), and from April 26 – white ones. Then, from May 19, a polar day will come to Norilsk for 68 days. Then everything will be repeated in the reverse order: on July 25 white nights will begin, on August 15 – twilight, from September 15 there will be a change of day and night, and on November 30 the polar night will again come.
