B) Explain method of determination of latitude by meridian altitude of Sun or Star with neat labeled diagram. CO3 12 The meridian altitude of the Sun’s lower limb was observed to be 41°12°26” at a place in longitude 72°20°45” W to determine the latitude of the place. The Sun was to the south of the zenith. The declination of the sun at GAN on the day of observation was 19°38°52” N, increasing 7.46” per hour and in semi-diameter 16°14°24”. Determine the Latitude of the place.
