For inhabitants of the northern hemisphere, the winter solstice process becomes most noticeable around December 1 when the sun appears to “move” south and get smaller. By the day of the actual winter solstice, the sun has reached its lowest point in the sky at -25.5°. Once it has reached this lowest point, an interesting thing happens: the sun appears to stop moving south for three days. After this, the sun moves 1° north, announcing the coming of spring. It will continue to move northward until the summer solstice, when it reaches its highest point.
