28 (4) the ८ara correction (i.e., the correction sional difference) In the case of the Moon, the same four following order: (1) the longitude correction, (2) the bltgantara correction, (3) the blujahala correction, (4) the ८ara correction. due to the Sun's ascen corrections are applied in the The correction for the euation of time due to the obliguity of the ecliptic has been neglected by the author of the present work, like all other early Hindu astronomers. This correction occurs for the first time in the works of Sripati (1039) and Bhaskara II (1150). Bhaskara II called it udayantara-satiskara and prescribed it for all planets. Lengths of day and might 21. (When the Sun is)in the northern hemisphere, the day increases and the might decreases by twice the 0.5us of the (Sun's) ascensional difference. (When the Sun is) in the southern hemisphere, the contrary is the case. What is meant is that when the Sun is the northern hemisphere length of day=30 ghaऽ+ twice the Sun's asc. diff. in usus, and length of might=30 ghatऽ- twice the Sun's ase. diff. 'in asus, and when the Sun is in the southern hemisphere length of day=30 gha! and length of might=30 gha ऽ+twice the Sun's asc. diff. in asu७ The truth of this can be easily seen from the celestial sphere The blugjantara correction for the Moon 22. The mean daily motion of the Moon multiplied by the Sun's blugjalala and divided by 21600 should be added to or subtracted from the mean longitude of the Moon (corrected for the longitude correction) as in the case of the Sun (i.e., ac cording as the Sun's mean anomaly is in the half-orbit commen cing with Libra or in that commencing with Aries).*
