Years ago, I think the correction was more like 17 degrees in New England.  I did some work on the geomagnetic field some years ago, and remembered getting magnetic variations for London, England over the last few  centuries. The pole really does move.

Hello Frantisek and others,

I wonder how much the magnetic pole has shifted.

I have been reviewing the operation of the Brunton Pocket Transit here. It has 
an adjustment for declination - the angular difference between the magnetic 
North Pole and the true rotational axis North Pole.

Here in Western Massachusetts it has been about 15 degrees East for a very long 
time. I wonder if that is changing.

Hi Bob,

did you take in mind  increasing magnetic  pole (and accompanied  aurora oval) 
eastern shift  from Canada towards Siberia ?
