    Study Notes

    Solar Cycle and Sunspots

    • The Solar Cycle is a periodic change in solar activity over approximately 11 years.
    • Sunspots are darker regions on the Sun's surface caused by magnetic activity.
    • Sunspots increase in number during the Solar Maximum phase of the cycle.
    • Sunspots do not change solar energy output.
    • Sunspots are caused by variations in the Sun's magnetic field.
    • A solar flare is a large explosion on the Sun's surface.
    • The average duration of the Solar Cycle is 11 years.
    • Sunspots can disrupt satellite communications.
    • Telescopes are primarily used to observe sunspots.
    • More sunspots do not necessarily mean more solar radiation, they are both related to the Solar Cycle, but not directly correlated.

    The Impact of the Solar Cycle on Earth

    • Increased sunspot activity during the Solar Maximum phase can disrupt satellite communications and cause auroras (Northern Lights) on Earth.
    • Solar flares and coronal mass ejections (CMEs) can impact Earth's atmosphere and technology, potentially causing power outages and disrupting radio communications.
    • The Solar Cycle influences Earth's climate and space weather, with significant implications for technology and life on Earth.
