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 41o12’26” at a
place in longitude 72o20’45” 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 19o38’52” N, increasing 7.46” per hour and in semi-diameter
