Comparison of solar minimum and maximum
Images in the visible light spectrum from NASA's Solar Dynamics Observatory (SDO), showing the appearance of the Sun at solar minimum (left, December 2019) compared to the solar maximum (right, August 2024). Sunspots are associated with solar activity and are used to track the progress of the solar cycle. During the solar minimum, the Sun is often devoid of spots.
