biscay variation

[Guest]

Could some kind person with a chart of Biscay give me the variation at position 50deg. 28 min N, 01deg. 14 min W as I need this to complete an excercise for my Yachtmaster and I don't currently have access to the correct chart.

There's something a bit funny here. 50 deg 28' N and 001deg 14' W is nowhere near Biscay. It is SSE of St Catherine's light on the IoW. The mag varn there was 4deg 35'W in 1990 and dec 10'E. So for this year it will be in the order of 2deg 45min W.
