true moon's place amongst the constellations at mean sunrise, stated in 10,000ths of the circle. The moon's place in degrees, minutes, and seconds can be found by Table XLV B, Vol. XIV
Thus, by the figures in Example 4 :
0 x 10 = 7070 Constant +7226

Nakshatra-index =5627=(Table LXVIII,colo. & 8,10)Visakha, by all systems.
nl This is approximately correct. (B) Greater exactness can be obtained by using the decimals, thus
cx 10 =7068-3930 Constant + 7226-3542

+1448-2272
5626-7925
There is here a little difference in the resulting nakshatra-index, which may in some cases be as great as nearly 10 unitu owing to the roughness of the earlier method.
(C) The value of at mean sunrise of the day in question enn also be obtained easily by my Tables for the sun's true longitude for each day of the solar year given in Vol. XIV above. The following shews method of work
! - In the present case the serial Dumber of the day in question was 241. True Meshsamkranti took place (868 Example 3) on Day 84 at 3h 55m after mean sunrise. The day of our date was (241-84) the 157th period (each of 24 horas) after the moment of true Mesha sankranti. On this 157th day at 3h 55 after mean sunrise the sun's true longitude, was, in 10,000ths of citele, 4182:0049 (Table XLVIII A, Vol. XIX above, p. 32.col. 9). Deduct the values for 3 hours (Tabla XLIX, p. 54, sun's true motion on that: 157 th duy) and 55 (Table L, maari motion in minutes), viz., respectively, 3-3852 and 1.0457, total, 4:4209..*
4182-0049
At wagn sunrise #34177574086 X V This is the value of . at mean sunrise of the 29 August, of onr date, and added to t (4137:57:40 +1448-2272), it gives us the correct nakshatra-index 5625-8012, shewing a slight difference of 0-0087 in regtilta.
