83m. 32s.—1h. 23m. 32s.
This represents the difference of sunrise due to latitude. That is to say, a place in 11° North latitude, and on the same meridian as Greenwich, would have its sunrise 1 hr. 24 min. later than Greenwich on the 13th May, 1912. Now the sunrise on this date at Greenwich was at 4 hrs. 13 min. a.m., and therefore at Kumbakonam the sunrise would be at 5 hrs. 37 min. a.m.
The longitude of Kumbakonam is 5 hrs. 18 min. east of Greenwich, and the equivalent Greenwich time of sunrise at Kumbakonam will be G.M.T., 0 hr. 19 min. a.m.
The Sun’s longitude at this time according to the Greenwich ephemeris is 1s. 21° 51´ 57´´, which we may call Taurus 21° 52´. This, therefore, represents the Indian estimate of the present value of Ayanámsha.
