Abstract

A series of computer programmes have been developed which give various types of information about solar eclipses. The first programme evaluates the times of solar and lunar conction and at the instant of each conction finds out whether the condition of a solar eclipse is satisfied. The information obtained by the first computer programme is fed to a second programme which evaluates the Besselian elements of the solar eclipse for the eclipse day. Using the Besselian elements a third programme evaluates the beginning and end of partial or total phase at a given location. A fourth programme determines the path of totality of the eclipse which is a plot of latitude versus longitude where the condition of totality is satisfied. Paths of totality of all total or annular solar eclipses during 19871990 are presented.
