What are the three best times of the day to take a sun sight for Sun Run Sun?

Taking a sun sight during navigation is crucial for accurately determining a vessel's position. The best times of day to take these sights benefit from optimal angles and conditions that enhance accuracy. Mid-morning and mid-afternoon are advantageous because the sun is generally high enough in the sky that its position can be clearly observed without excessive distortion from atmospheric conditions. This also means that the sun is positioned well for taking several readings with clarity. When the sun passes through the meridian of longitude, it is at its highest point in the sky for that location, also known as solar noon. This time offers a particularly stable reference for determining latitude because the sun's position changes at the slowest rate, allowing navigators to obtain the most accurate readings. Collectively, taking sun sights at all these times capitalizes on the variations in sunlight and the position of the sun in relation to the earth, ensuring that navigators can triangulate their position with a high degree of certainty. This comprehensive approach helps in obtaining clearer and more accurate data for navigational calculations.
