Grand Forks North Dakota USA Armillary Dial 282
A large brass and cast iron armillary dial with full equatorial and equinoctial colure rings, two tropic rings and Arctic and Antarctic circle rings. The sphere is tilted so the central gnomon points to celestial north and is mounted in a four-legged stand. The gnomon includes a nodus that casts a shadow on a plate with engraved date analemma.
