The methods of taking photos of the sun over months of time, called Solargraphy, was presented by Art Paque, and then there were talks on the operation of cylindrical sundials, sundials that can show standard time, an update on the Mars sundial, and discussions on solar alignments, heliodons and stair shadows.

Helmut Sonderegger, this year’s recipient of the Sawyer Dialing Prize discussed the Rheticus Memorial sundial designed for Georg Joachim Rheticus, the first Copernican.
