Solar maximum

Definition

Solar maximum is the period during the solar cycle when the Sun's magnetic activity is at its peak. This phase is characterized by an increased number of sunspots, solar flares, and coronal mass ejections.

5 Must Know Facts For Your Next Test

1. Solar maximum occurs approximately every 11 years as part of the solar cycle.
2. During solar maximum, the Sun exhibits a higher number of sunspots compared to solar minimum.
3. Increased solar activity during this period can enhance space weather phenomena, affecting satellite operations and communications on Earth.
4. Solar maximum can lead to more frequent and intense auroras due to interactions between solar wind and Earth's magnetosphere.
5. Observations of historical solar maxima have provided insights into patterns of space weather and its potential impact on modern technology.
