○ solar winds

Explanation:

Aurora australis (Southern Lights) is caused by solar winds. Solar winds are streams of charged particles (electrons and protons) released from the sun's corona. When these particles interact with Earth's magnetic field and atmosphere, they create the light displays known as auroras. Solar flares are sudden eruptions of electromagnetic radiation from the sun's surface. Sunspots are temporary phenomena on the sun's photosphere that appear as spots darker than the surrounding areas. Prominences are large, bright features extending outward from the sun's surface.

Answer:

solar winds
