- Description:
- An 8x36 inch polar noon meridian dial of wood and steel pipe. The dial face is inclined at the latitude angle and the shadow-casting 36-inch gnomon pole is perpendicular to the dial face, pointing at the local meridian on the celestial equator. The gnomon pole shadow shows the declination of the sun, with the shadow extending below the gnomon in spring and summer, and above the gnomon in fall and winter. Short rods at the tip of the gnomon cast a cross-shaped shadow on the dial face, marking the date on the nail head analemma on the dial face. At local noon the gnomon shadow is vertical; the face and gnomon size are selected to allow the shadow to always fall on the dial face at noon throughout the year. On the equinoxes, the cross shadow bisects the gnomon base. This dial is on private property but may be seen from the public sidewalk. For closer inspection, the owner may be contacted.
