Videos and Photos of 2013 Space Weather actuals and predictions for Sun Storms, Solar Flares, Solar Coronal Mass Ejections and more ...
Space Weatherincluding solar flares and CMEs are not a danger to humans on Earth's surface, as the planet's magnetic field (magnetosphere) and atmosphere deflect and absorb the solar energy and particles. The sun storms can pose some risks to astronauts, and they can upset the electronics and transmissions on science, military, and communications satellites. Closer to Earth's surface, solar activity can cause disruptions of radio signals (particularly HF), provide a small dose of radiation to passengers on high-latitude flights, and provoke auroras (northern and southern lights). Note the brightening of the solar surface as gas was superheated and magnetically supercharged. By the third (right) image, a stream of solar material is seen flowing off into space above the hot spot, likely solar protons and a coronal mass ejection.

Fast-moving protons from a solar energetic particle (SEP) event cause interference that looks like snow in these images from the Solar Heliospheric Observatory taken on January 23, 2012.
