Situated at Sanae, Dronning Maud Land, on the continent of Antarctica, 71 40' 10" south and 2 48' 4" west, this sundial is believed to be the most southerly in the world and the only sundial on that continent. It is 400mm square. The dial was a gift from South Africans to the Sanae 43 team of intrepid engineers and scientists who spend a year in that lonely and isolated place. It stands next to the South African National Antarctic Expedition Base and is longitude corrected for its position in the Greenwich Meridian Time Zone. It bears the Equation of Time so that to obtain the legal time only the Equation must be applied to any reading. Being so far south and at the peak of summer it is able to be read for 24 hours per day and is calibrated for that. It is accurate to within 30 seconds. The dial is constructed from solid unleaded brass throughout and is mounted on a central pillar because expansion and contraction make corner mountings impractical. The dial is designed to withstand wind speeds of
250 k.p.h. and temperatures from +6C to -80C and has already withstood wind gusts of 163k.p.h. and -38C.
It bears the logos of the sponsoring companies and the 'Proudly South African' logo plus the Sanae 43 team logo.
