Solar Storms and Space Weather Solar Flares o Intense eruptions of magnetic field, emitting up to 10% of total energy of the sun in a view seconds o Flares caused by release of magnetic energy through “reconnection” of magnetic field lines Coronal Mass ejections – send bursts of energetic charged particles out through the solar system o Happen when there is a lot of solar activity taking place o Can distort the earth’s magnetic field – if you are at high latitudes you can see auroras Auroras: charged particles from solar wind and CMEs interacting with Earth’s magnetic field where the field lines converge (north and south magnetic pole) Earth in the Way Solar wind, CMEs and flares dump enormous amounts of charged particles and high energy radiation on earth o Particles get directed by earth’s magnetic field Particles end up spiraling around field o Collision of charged particles with atoms in earth’s atmosphere generates light: aurorae o High energy particles and radiation can deposit
