Spherical Astronomy Problems And Solutions [extra Quality] -

At rising or setting, the altitude h = 0° (ignoring refraction and semi-diameter). However, the center of the Sun or Moon is slightly below the horizon due to refraction (typically +34' correction).

Below is a guide to fundamental spherical astronomy problems, their mathematical solutions, and the logic behind them. 1. The Basics: The Sine and Cosine Rules spherical astronomy problems and solutions
