Time is intimately linked to Earth's rotation. Solving positional problems requires a clear understanding of different time systems. The most important ones are:
Solving problems in spherical astronomy requires a firm grasp of the coordinate systems used to map the heavens. The two most common are:
Determine the celestial coordinates (right ascension, declination) of a star located at an altitude of 60° and an azimuth of 120° at a latitude of 30°.
aupper=90∘−ϕ+δa sub upper end-sub equals 90 raised to the composed with power minus phi plus delta
