Running the calculations again, it appears that you are correct. When
I get to my nav notebook, I will check my work and see where I went wrong.

I've just finished working the exercise and all the results are in good
accordance with yours except for the deviation calculated at sunset.
Sun's amplitude according to my calculation is 23,9 which gives an azimut of
293,9, thus gyrocompass error is 0,8 W.
The ship was then steering 179,2 true and given a variation of 1,3 E this
yields a deviation of 9,9 E (almost 3 deg less than yours).
Am I wrong?
