Sunspots

  • Areas of gas on the Sun's surface that are cooler than the gases around them

  • Cooler gases don't give off as much light

  • Can be larger than the Earth

  • The # of sunspots varies in a regular cycle, with the most appearing about once every 11 years

  • Affects on Earth: Auroras, disruptions in power, radio, and satellites

Prominences

  • Huge loops of gas that often link different parts of sunspot regions

  • These loops of gas are anchored to the photosphere and extend to the corona

  • Can last for months

  • Can disrupt navigation systems, surges/blackouts in electrical systems, damage/disrupt satellites

5

Solar Flare

  • A release of magnetic energy that heats gas in the Sun's atmosphere and causes an eruption into space

  • Typically lasts for a few minutes

  • Can cause the loss of power and satellite

Solar Winds

  • Streams of electrical particles from the Sun

  • Solar flares can increase the amount of particles

  • Earth's magnetic field blocks the majority of solar winds except on the North and South Poles

  • At the poles, the particles create electric currents that cause gas in the atmosphere to glow (Northern Lights/Southern Lights)

  • Worst case scenarios: too many particles entering the atmosphere can cause magnetic storms and blackouts
