Explanation

The Sun is directly overhead at “high-noon” on the equator twice per year, at the two equinoxes. On the Arctic Circle, the Sun does not set at all on the Summer Solstice which occurs on 21st June. On that oneday, the Sun traces a complete circle just above the horizon as the Earth rotates.
