This is the inverse of the previous problem. Navigators often know a star's altitude and azimuth but need their own position (latitude) or the star's celestial coordinates.
a=90∘−67∘55′=22∘05′a equals 90 raised to the composed with power minus 67 raised to the composed with power 55 prime equals 22 raised to the composed with power 05 prime ✅ The star's altitude is approximately . 2. Circumpolar Stars Problem: At what geographic latitude ( ) is the star Castor ( ) circumpolar (never sets)? spherical astronomy problems and solutions
Astronomers use the to find the angular separation ( ) between two points The Formula: This is the inverse of the previous problem
Apply corrections in order: Measured altitude → refraction → parallax → semidiameter → true altitude. spherical astronomy problems and solutions
