If Si and Mj denote the longitudes of the Sun and the Moon at sunrise on the day following full moon, then Sun's longitude at the time of opposition of the Sun and Moon =Si" pratipad-riadls treated as minutes of arc, and Moon's longitude at the time of opposition of the Sun and Moon ^M^pratipad-riedis treated as minutes of arc -[Mi — (^+6 signs}]; and if 'SJ and M/ denote the longitudes of the Sun and the Moon at sunrise on the day following new moon, then Sun's longitude at the time of conjunction of the Sun and Moon —5^' ^pratipad-riadls treated as minutes of arc, and Moon's longitude at the time of conjunction of the Sun and Moon s= M t ' —pratipad-riadls treated as minutes of arc By parvariadls is meant "the riddis of the full moon or new moon tithi (called parva) which are to elapse at sunrise on that day". Similarly, by pratipad-riadls is meant "the riadls of the next tithi (called pratipad or pratt- pada) which elapse at sunrise on that day." The above rule gives only an approximate result because it is based on the assumption that the Sun travels at the rate of one minute of arc per riadl, but for practical purposes it is good enough. Mean distances of the Sun and the Moon in terms oiyojanas : 2, 459585 is (myojanas) the (mean) distance of the Sun and 34377 that of the Moon. 1 A rule for finding the true distances of the Sun and the Moon in terms oiyojanas : 3. These (above-mentioned mean distances of the Sun and the Moon) multiplied by their true distances in minutes
- The same distances are given in MBh, v. 2; and SiDVr, I» iV. 4.
