The magnetic field flips when the Sun is at its most active, in a phase called the solar maximum. After the flip, our star calms down until it reaches the
Solar cycle
Because the solar cycle reflects magnetic activity, various magnetically driven solar phenomena follow the solar cycle, including sunspots, faculae/plage, network, and coronal mass ejections.

SOLAR CYCLE - BASICS Definition The solar cycle is the main source of periodic solar variation on Earth which drives variations in space weather and to some degree weather on the ground

Solar cycle, period of about 11 years in which fluctuations in the number and size of sunspots and solar prominences are repeated. Solar cycle 25 began in 2019 and will reach maximum in
Solar Cycle – Definition & Detailed Explanation
What is a Solar Cycle? The solar cycle is the approximately 11-year period of change in the Sun''s activity levels. This cycle is characterized by the rise and fall of sunspots,
14.1.3: The Solar Cycle
We now know that the Sun is in a perpetual state of change: its surface is a seething, bubbling cauldron of hot gas. Areas that are darker and cooler than the rest of the surface come and go.

The magnetic field flips when the Sun is at its most active, in a phase called the solar maximum. After the flip, our star calms down until it reaches the solar minimum and a new cycle begins.
The Solar Cycle
Individual sunspots come and go, with lifetimes that range from a few hours to a few months. If a spot lasts and develops, it usually consists of two

List of solar cycles
The following table gives the number of days so far in cycle 25 against the number up to the same point in cycle 24, which have passed various thresholds for the numbers of sunspots.
What Is the Solar Cycle? | NASA Space Place – NASA Science
The beginning of a solar cycle is a solar minimum, or when the Sun has the least sunspots. Over time, solar activity—and the number of sunspots—increases.
The Solar Cycle
Individual sunspots come and go, with lifetimes that range from a few hours to a few months. If a spot lasts and develops, it usually consists of two parts: an inner darker core, the umbra, and a
