What is Usually seen on clear winter nights in an array of shapes and colors near the earth magnetic poles?

What is usually seen on clear winter nights near the Earth's magnetic poles are the auroras, specifically the Aurora Borealis (Northern Lights) in the Arctic and the Aurora Australis (Southern Lights) in the Antarctic. These natural light displays occur due to the interaction of solar winds with the Earth's magnetic field and atmosphere, creating stunning arrays of shapes and colors, primarily green, pink, and purple. The phenomenon is especially vibrant in winter due to longer nights and clearer skies.
