b) Explain method of determination of latitude by meridian altitude of Sun or Star

with neat labeled diagram.

B) The meridian altitude of the Sun’s lower limb was observed to be 41^{o}12’26” at a

place in longitude 72^{o}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^{o}38’52” N, increasing 7.46” per hour and in semi-diameter
