What happens at Local Apparent Noon?

At Local Apparent Noon, the sun reaches its highest point in the sky for that specific location on Earth. This phenomenon occurs when the sun is at the meridian, which is the local longitude of the observer. At this moment, the sun appears to be directly overhead if one is at the Tropics, and it is at its zenith for that latitude. This is crucial for navigation and timekeeping, as it can be used to determine local time based on the sun's position. Understanding this term is essential for mariners and navigators who rely on celestial navigation techniques.
