PROBLEM OF COORDINATE SYSTEMS

1. In a place of latitude 48◦ N, a star of declination 60◦ N is observed. What is its zenith

distance at upper and lower culmination?

2. The zenith distances of a star at upper culmination (south of the zenith) and lower

culmination are 24◦ and 74◦ respectively. Calculate the latitude of the observer and the declination of the star.
