Fellow Shadow Watchers, While querying current magnetic variation at a UK location I was directed to
The British Geological Survey Homepage which others might find useful. http://www.geomag.bgs.ac.uk Click on 'Navigation Models & Charts' Click on 'Grid Magnetic Angle Calculator' Insert correct references in the boxes: 'Grid East Value < ? > (0-700,000) 'Grid North value' < ? > (0-1,300,000) and a recent figure for magnetic variation at that location is generated. As Latitude and longitude are my preferred mode I last used OS map references when doing A level geography with my classmate Prince Henry the Navigator.....well.....it seems as long ago as that :-). Things now are not as I seem to recall them. 'UK Streetmap' on the WWW returns the following values for a client's location OSX 35XXXX (blanked for confidentiallity) OSY 67XXXX Am I correct in thinking that: OSX the 'Grid East Value' and OSY the 'Grid North Value? in this context? O-) Thanks in anticipation. Tony Moss -
