VI. 14 VI. VĀS.-PAUL. SIDDHĀNTA – LUNAR ECLIPSE 171 See how close this is to the time calculated, viz. nā. 5-46. The Moon’s orbit does not touch the circle of totality. Therefore there is no total obscuration, as already found by calculation. The arc in the figure from the east point of place to the first point of contact gives the direction of the point at the beginning, and the arc from the west-point of place to the point of last contact gives the direction at the end. We have amended matena into yutona, nabahu into Rāhu, ekachanoni into ekasthānāni, yāmasabū into śaśāṅka and pūrvāparayośca into pūrvāparāyāśca as necessitated by the context and proximity of the lettering. [रविचन्द्रग्रहणयोर्भेदः] स्वे भूच्छायामिन्दुः स्पृशत्यतः स्पृश्यते न पश्चार्द्धे । भानुग्रहेऽर्कमिन्दुः प्राक् प्रग्रहणं रवेर्नाऽतः ॥ १४ ॥ Lunar and solar eclipses – Differences 14. In the lunar eclipse, the Moon, (moving eastward), contacts the earth’s shadow. Therefore the ‘first contact’ (occurs at the eastern limb of the Moon, and so) does not occur at the Moon’s western limb. In the solar eclipse, the Moon meets the Sun, and therefore, (the Sun being contacted as its western limb), the first contact does not occur at the eastern limb of the Sun. The Moon’s motion being more than thirteen times that of the Sun or the Shadow, (whose motion is the same as that of the Sun), it moves eastwards relative to the Sun or Shadow and con- tacts them at their western limb, and its own eastern part. As the lunar and solar eclipses are with reference to the Moon and the Sun, respectively, the first contacts are at the eastern and western limbs, respectively. It need not be mentioned that the last contacts are, respectively, on the western and eastern limbs. 14. Quoted Utpala on BS. 5.12 C. स्पृशति तथा स्पृशति दृश्यते पश्चात् । 14a. U. स्वं.
