Since we have a recent post and some discussion of checking the compass at sea, here is an example of a afternoon Azimuth of the sun I shot while underway from South Korea to Saipan, CNMI: Azimuth of the Sun On 11 November 2006, a ship was in position Latitude 17 deg 38.6� North, Longitude 142 deg 22.7� East. At 04h 17m 31s UTC, a gyro bearing was taking of the sun. The observed gyro azimuth was 223.0 degrees. The ship�s heading was 125 deg per gyro compass, and 110 degrees per magnetic compass. Local Variation was 0.2 deg West. Determine the Gyro compass error, magnetic compass error and deviation of the magnetic compass at that heading. As usual, I will standby for any questions and will post my reduction in a day or two. Please note how you came about your answer. Did you use tables, if so, which ones? Was it a calculator, computer etc? Thanks, and have fun!
