It is a singular event each orbit at the South Pole as a component of the great Polar day/night cycle.
The South Pole, where daily rotation is absent, turns through the circle of illumination and the Sun comes into view for the first time in 6 months. The surface rotation parallel to the orbital plane actually occurs for the entire surface of the planet so where the daily cycle meshes with the annual cycle ,we experience this as the seasons.
