The Campbell-Stokes sunshine recorder at the South Pole measures sunshine using a glass sphere to amplify the sun’s intensity to burn a line into paper.

Meteorologist Jeff DeRosa took this photo during the 4 December 2021 partial solar eclipse.

The gap in the burn line indicates when the sun's rays were not intense enough to burn the paper.

At the start of the eclipse, the South Pole temperature was -26.5 °F / -32.5°C. When the sun was partially covered, the temperature dropped to -35.5 °F / -37.5°C.
