Summary
| Description | Top view of an equatorial sundial. The hour lines are spaced equally about the circle, and the shadow of the cylindrical gnomon moves uniformly about. The height of the gnomon is 2.5 units and the outer radius of the dial is 6.0 units. This animation depicts the motion of the shadow from 3 a.m. to 9 p.m. on mid-summer's day, when the sun is at its highest declination. Sunset and sunrise occurs at 3am and 9pm on that day near the latitude 57.5°, roughly the latitude of Aberdeen or Gothenburg. Made 15 January 2008 by me using Blender. |
