The highest point of the sun in Bairiki

Bairiki, the capital of the country, lies at a northern latitude of φ = 01 ° 20 ‘and thus in the middle of the tropics.

If the declination δ of the sun corresponds to the value of 01 ° 20 ‘N and thus the image point of the sun is exactly above the city, the sun is vertically above the city. This happens exactly twice a year, roughly 6 days after March 21st and 6 days before September 21st.


If the image point of the sun and thus the declination is north of the latitude of Bairiki, the sun is not in the south at noon, as in our latitudes, but in the north. In this case, the sun moves from east to north to west, where, like us, it sets.
