| Description: |
- Analemmatic sundial 16' x 10' (4.8m x 3m) painted as a full ellipse on the driveway to a house. Shows local solar time. Time corrections to obtain civil time (Equation of Time and longitude offset) are given for the first of each month on the Zodiac Walkway. Sunrise and Sunset sighting points (seasonal or "Bailey" points) are provided for a theoretical horizon, but are not useful as the dial site is within a valley. The perimeter of the ellipse is marked with great circle navigation directions for a selection of historical solar and celestial observatories, especially for North America, but all historically inhabited continents are represented. A QR code is provided for a link to a website with instructions for the dial, reference links on sundials (including NASS), and links for the selected observatories on the perimeter. The 2 degree slope of the driveway was not compensated for in the sundial layout, but the dial is unshaded from roughly 9:00 am to 5:00 pm in the summer.
