Hoping someone can help me calculate/understand my magnetic variation (v A r) setting on my ST60 auto pilot. I have calculated my variation/declination as show below using the NOAA calculator with my lat/long coordinates.
Date Declination
2021-06-06 9° 28' W ± 0° 24' changing by 0° 1' E per year
Where I am getting confused with whether this 9°W is a plus or minus (+/-) input. Reading online i am seeing the following:
By convention, declination is positive when magnetic north is east of true north, and negative when it is to the west.
Am I West of magnetic north or is West of me?
Anyone have any experience with this?
