83. On 11 May in DR position LAT 28°13.7'N, LONG 168°36.3'E, you observe an amplitude of the Sun. The Sun's center is on the celestial horizon and bears 283°psc. The chronometer reads 07h 13m 19s and is 02m 56s slow. Variation in the area is 13°E. What is the deviation of the standard magnetic compass?
The deviation is 5.6W. The true bearing of the Sun (290.4T) minus the observed compass bearing (283psc) and the variation (13E) equals the deviation.
