Description:
  • This analemmatic sundial is painted on concrete. It is similar to John Carmichael's human sundial at Flandrau Planetarium at the University of Arizona. The orange background was painted by hand with acrylic paint on top of the blue acrylic court surface. Lettering and other markings were painted with Rustoleum spray enamel using stencils from Stencilease.com. Final touch up painting was done by hand. It took a three man team ten days to paint. It's quarter hour time marks are longitude corrected and shows Standard Time when readings are adjusted using the Equation of Time. It includes a central Date Line for standing, using monthly and weekly marks. There is a Solar Noon mark, and Bailey Points to indicate the direction of sunrise and sunset.
