The functional principle of the HELIOS Subsolaris, the projection of sunlight onto a globe-shaped screen, allows the simultaneous display of Middle European Time, the date and the apparent migration of the Sun, all with the highest possible degree of precision. The zenith position, daily migration, seasons, solstice, equinox – the Sun itself makes these natural phenomena visible on the screen.
