160. At 2232 ZT on 14 July you are in DR position LAT 33° 52' S, LONG 150° 03' W, when you observe an amplitude of Jupiter. The planet is about one Sun's diameter above the visible horizon and bears 268.5° pgc. The variation is 15° E. What is the gyro error?
The computed true bearing of Jupiter is 269.5T, while the gyro compass indicated 268.5 pgc, resulting in a gyro error of 1.0 East.
