161. On 16 September your vessel's 0736 zone time DR position is LAT 27° 34' S, LONG 174° 49' E, when an azimuth of the Sun is observed. The chronometer time of the sight is 07h 38m 11s, and the Sun is bearing 079.8° per gyrocompass. The chronometer error is 01m 46s fast, and the variation in the area is 11.0° W. At the time of the sight, the helmsman reports that he was heading 252° pgc and 258° per magnetic compass. What is the deviation of the magnetic compass?
The magnetic compass deviation is 3 East. This is determined by reconciling the true heading derived from the gyro and Sun azimuth with the magnetic compass heading, variation, and deviation relationship.
