A ship is in position Lat 15 deg 14.0�N and Longitude 145 deg 40�E. The sky was partly cloudy and an ex-meridian sight of the sun was taken at local zone time 12h 08m 46s (ZD -10). Hs (lower limb) was 85 deg 22.0�, IE was 1.0� off the arc, height of eye was 106 ft, temperature was 90 deg F, and the barometer read 1010 mb. Calculate Latitude by ex-meridian. Challenge: reduce the sight as a regular sunline and plot both lines and see what, if any, difference there is. If you choose to post, please let us know how you at your �a� and �C� values for the correction.
