Cool Tool

Equinox coming, equinox coming. Weather permitting, perhaps on next Monday can get a nice reassuring experience of "Yes, by golly, the sun rises in the (exactly) east and sets in the (exactly) west."

My old sighting compass does not hold its declination setting anymore, and I have to keep resetting it. So what is it (exactly) at the moment, here? Estimated Value of Magnetic Declination. "Declination = 17° 35' E changing by 0° 10' W/year". Thank you, NOAA.

PS Note to self: used the lat/long of the airport, Latitude: 48.11888888; Longitude: -123.49361111.
