254 PAÑCASIDDHĀNTIKĀ XIII.23 Visibility of the Sun 20. At any latitude, the equatorial Sun is bent so many degrees south at mid- day, as the north pole is raised up from the north point of the horizon. 21. Going north from Ujjain, 373 1/3 yojanas, the stellar sphere, (marked by the 27 asterisms of the ecliptic rising in an order) becomes discontinuous, (i.e. the order in the rising is disrupted). Note. At 66° North latitude, which is 42°, (i.e. 66° – 24°), north of Ujjain, peculiarities occur in the rising of the signs of the ecliptic, duration of day-time etc. 42° = 373 1/3 yojanas. (षष्टिर्नाड्य)स्तस्मिन् सकृदुदितो दृश्यते दिवसनाथः | परतः परतो बहुतरमा षण्मासादिति सुमेरौ || २२ || योजनपञ्चनवांशां स्त्र्यधिकांश्च चतुःशतीमुदगवन्त्याः | गत्वा न धनुर्मकरौ कदाचिदपि दर्शनं व्रजतः ||२३ || 22. At that latitude, the Sun can be visible even throughout a day. North and north of this place, the Sun may not set more and more than one day, until at the north-pole it will not set for six months at a stretch. 23. At a distance greater than 403 5/9 yojanas north of Ujjain, the signs Dhanus and Makara can never be visible. Note. The Dhanus and Makara segments of the ecliptic have a south declination greater than 20° 36'. In the north latitudes 90° – 20° 36' (= 69° 24') and beyond, the zenith distance of these signs becomes greater than 90°, and so they are not visible in those latitudes. 69° 24' is 45° 24' north of Ujjain, i.e. 45° 24' × 8 8/9 = 403 8/9 yojanas north. 20-29.
