The highest point of the sun in Port Moresby

Port Moresby,

the capital of the country, is located at a southern latitude of φ = 09 ° 30 ‘, i.e. in the tropics.

If the declination of the sun has the value 09 ° 30 ‘S and the image point of the sun is thus exactly above the city, the sun is vertically above the city. This happens exactly twice a year, roughly 37 days before March 21st and 37 days after September 21st.


If the image point of the sun and thus the declination δ is north of the latitude of Port Moresby, 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.
