* Summer Solstice (December 21/22): The sun is at its highest point in the sky, reaching an angle of approximately 23.5 degrees above the horizon. This is the time of the 24-hour daylight period at the South Pole.
* Winter Solstice (June 20/21): The sun is at its lowest point in the sky, staying below the horizon for 24 hours. This is the time of the 24-hour night period at the South Pole.
* Equinoxes (March 20/21 and September 22/23): On these days, the sun is directly over the equator. At the South Pole, the sun would be at an angle of 0 degrees (on the horizon), meaning it would rise and set in a circle around the pole.
Important Note: These angles are approximate, and they vary slightly depending on the year.
