On 29th of October we could observe the last sunset this year at the Polish Polar Station in Hornsund. After around two weeks of civil twilight we entered a period of continuous night, which will last until the end of January, with first apparent sunrise taking place on 12th February.
- Why does length of day and night depend on latitude?
- How dark is polar night at different locations within the Arctic Circle?
- What do reindeer have in common with the Earth’s rotation angle?
We will answer these questions during the lesson broadcast from the Polish Polar Station, covering rotational and orbital motion of Earth and their consequences, with focus on high latitudes.
