265. On 23 October in DR position LAT 21° 13.0' N, LONG 152° 18.0' E, you observe an amplitude of the Sun. The Sun's center is on the visible horizon and bears 259° psc. The chronometer reads 07h 21m 46s and is 01m 32s slow. Variation in the area is 5° E. What is the deviation of the magnetic compass?
The Sun's true bearing was calculated as 258.1T, which, when compared to the observed compass bearing of 259 and accounting for a 5E variation, yields a compass deviation of 5.9W.
