The period of greatest solar activity in the Sun's approximately 11-year cycle, characterized by the highest number of sunspots, solar flares, and coronal mass ejections. During this time, the Sun's magnetic field is most complex and dynamic.
From Latin 'solaris' meaning of the sun and 'maximum' meaning greatest. The term developed in the 19th century as astronomers recognized the cyclical nature of sunspot activity and established that solar activity peaks and valleys follow a regular pattern.
Solar maximum is when our star throws its biggest temper tantrums! During these peak activity periods, the Sun can unleash magnetic storms so powerful they can disrupt satellites, create aurora at tropical latitudes, and even affect power grids on Earth.
