350. On 4 July your vessel's 1722 zone time DR position is LAT 34°30'S, LONG 174°48'E, when an amplitude of the Sun is observed. The sun's center is on the visible horizon and bears 282° per standard magnetic compass. Variation in the area is 17.2°E. The chronometer reads 05h 21m 48s and is 02m 01s fast. What is the deviation of the compass?
The compass deviation is 1.5W. The Sun's true bearing was calculated from its declination and latitude, then converted to magnetic bearing using the area's variation. The difference between the observed compass bearing and the calculated magnetic bearing indicates a west deviation.
