Let's say I am in Brasilia (latitude = 15.78°S). This is obviously south of the equator but north of the tropic of capricorn. So on the summer solstice I know that the Sun's declination is +23.26°. Does this mean that the sun will appear directly north at solar noon? Thanks.
The Sun at solar noon (meaning that it is on the meridian) will be in one of these directions:
- Due south if the declination of the Sun is less that your latitude. (For Brasilia, that occurs from Nov 6 to Feb 5, approximately)
- Directly overhead (at the zenith) if the declination of the Sun is the same as your latitude. (For Brasilia, that occurs Nov 5 and Feb 6, approximately)
- Due north if the declination of the Sun is more than your latitude. (For Brasilia, that occurs from Feb 7 to Nov 4, approximately)
