ACTIVITIES ON THE SUN

• Solar Wind


  Stream of high-energy particles sent into space which causes the light displays:

  • "aurora borealis" if seen fr. Northern Hemisphere
  • "aurora australis" if seen fr. Southern Hemisphere
• Prominences


  Storms that look like huge arches extending outward the Sun's surface that could last for several days.
• Solar Flares


  More intense than prominences and last for only about 15 minutes.
• Sunspots


  Dark, cooler parts of the Sun's surface caused by changes in the sun's magnetic field.
