  1. SOLAR FLARES AND ERUPTIONS Lyndsay Fletcher University of Glasgow

  2. Sunspots - hotbeds of solar activity

  3. Solar minimum, solar maximum

  4. An active region seen by Hinode

  5. Winding up the magnetic field Gas at the solar equator has a higher speed than that at the poles. This ‘winds up’ the magnetic field - like stretching a rubber band

  6. Magnetic Loops

  7. Twisted loops images:TRACE/NASA

  8. A Solar Flare An explosion in the Sun’s corona cause by magnetic energy build-up

  9. Start of a coronal mass ejection A billion tonnes of ionised gas, moving at a million kilometers per hour

  10. Coronal mass ejections seen by SOHO

  11. Coronal mass ejections seen by SOHO During solar maximum, the Sun produces about 3 big mass ejections per day

  12. We live inside the atmosphere of a star! How do flares and eruptions affect Earth?
