Explanation:

Auroras (including aurora australis) are caused by charged particles from the Sun, carried by solar winds, interacting with Earth's magnetic field and atmosphere. Solar flares are intense bursts of radiation, sunspots are cooler regions on the Sun's surface, and prominences are large loops of gas on the Sun—none directly cause auroras like solar winds do.
