Of the satellite picture Solar Dynamics Observatory, there is activity on the surface of the star and film material, which measure usually hundreds of thousands of kilometers.
Risks on Earth after the eruption
Although very beautiful, these eruptions are of particular danger eruption emits radiation (gamma rays, X, radio waves …) and a cloud of charged particles which provides one to three days to reach the Earth. And disrupt communications, the GPS signal, some electronic devices may cause magnetic or damage to the electricity distribution networks thunderstorms.
In space, the radiation levels that follows increases suddenly, which could make disused satellites or shuttles and even hurt the astronauts.
Finally, they are responsible for the northern lights visible in the sky at high latitudes, mainly near the Arctic and Antarctic. And indeed, a series was captured on December 22, less than three days after the eruption in question:
