Heliacal Rising of Canopus in Indian Astronomy (2016)

unapi

In the present paper we discuss briefly the phenomenon of heliacal rising and setting of stars in general and of Canopus in particular. The importance of star Agastya (Canopus), apart from its religious significance, lies in its becoming circumpolar for different latitudes during different periods, usually in intervals of thousands of years. In this paper, we show how star Canopus which became circumpolar for an extreme North Indian latitude, attained some status after a couple of thousands of years for a lesser North Indian latitude. Thus, the course of circumpolarity of Canopus moves southwards reducing the terrestrial latitude successively until it reaches a southern limit. Then, the star reverses its course moving northward until it reaches the northern limit of terrestrial latitude.
