Abstract
Calculate the gnomon and shadow of the Moon in the above manner. From these calculate the dṛkkarṇa in terms of yojana-s. Using the dṛkkarṇa-yojana calculate the minutes of the corresponding lambana. The minutes of lambana of the Sun and Moon are to be applied, respectively, to the (true longitudes of) Sun and Moon. When the resulting true longitudes of the two are the same, that will indicate the time of the middle of the eclipse.
