Required the Lagna Sphutam, that is, the Longitude of the Ascendant at 39 gh. 30V. gh. from Sunrise on Friday the 28th May 1886, for a place whose Latitude is 11°.

From the Almanac we find that the Sun entered Taurus at 56 gh. 40V. gh. on the 12th May, and quits the sign at 12. gh. 27V. gh. on the 13th June.

Therefore time taken by the Sun to move through sign Taurus, = 3 gh. 20V. gh. + 31 days+ 12 gh. 27V. gh. = 31 days 15 gh. 47V. gh. = 1, 12, 500V. ghs. Time from Sun - rise on the 28th May to the end of the Sun's course through Taurus = 16 days 12 gh. 27V. gh.

- 58,327V. ghs.

Time of Oblique Ascension of

=

5 gh. 6v. gh.

Taurus for Latitude 11°

=

306V. gh. (vide Table A).

Therefore, time of Oblique ascension of the portion of Taurus to be passed over by the Sun on the morning of the 306 x 58,327

28th =----------------- 2gh. 39V. gh.

1,12,500

Subtracting this from 39gh. 30v. gh. we get time of Oblique Ascension of signs from Gemini =39 gh.30v.gh. - 2gh. 39v - gh = 36 gh. 51v. gh.

From table B we find that time of oblique ascension of signs for Gemini to Scorpio = 31 gh. 36V. gh.

Therefore time of Oblique Ascension of portion Sagittari that has risen above the horizon.

= 36 gh. 51v. gh. - 31 gh. 36V. gh. = 5 gh. 15v. gh. = 315v. gh.

Time of oblique ascension of the degrees of Sagittari for Latitude 11°, is 5 gh. 21v. gh. (Vide Table A) - 32r.v. gh.

Therefore portion of Sagittari that has risen above the 30 x 315

horizon =------------ 290 26', Sagittari being the 9th sign from 321 Aries.

Lagna Sphutam required is 8s 290 26'. The Bhavasphutam process is too complicated to be given here. The Reader is referred to Baskaracharya's work on Astronomy.
