What are the 4 features of our sun that change over short periods of time?

The sun exhibits several features that change over short periods, including sunspots, solar flares, prominences, and coronal mass ejections (CMEs). Sunspots are temporary dark spots on the sun's surface caused by magnetic activity, while solar flares are sudden bursts of energy that release radiation. Prominences are large, loop-like structures of plasma that can rise and fall over days. CMEs are massive bursts of solar wind and magnetic fields rising above the solar corona or being released into space, often occurring over hours to days.
