The sun was observed to have a north polar distance of 69°36'37" and a zenith distance of 46°12'10" when the theodolite was brought tangent to its upper limb. The index error was found to be 10'30", whereas the parallax and astronomic refraction were measured as 32" and l’13” respectively. The sun's semi-diameter was given as 26'. The observation was made at 1:25:30 PM where the hourly variation was found to be -36.2". Determine the azimuth of the sun.
