Abstract

An analysis is carried out of methods for solving a certain class of problems in spherical astronomy related to calculating the altitudes of celestial bodies at culmination. An original method for solving problems of this type using the construction of a “latitude–declination” diagram is presented. Examples of problem solutions are considered.
