The Sun
By Samantha Kline
Occurring when there is an explosion on the sun, solar flares take place when stored energy in twisted magnetic fields is suddenly released. The are three categories to define solar flares are x-class flares, m- class flares and c-class flares. X-class flares are rather large and can result in worldwide radio black outs and extreme radiation storms. M-class flares are medium sized and sometimes cause minor radio blackouts in Earth's polar regions. The smallest of the three, C-class flares usually result in very few noticeable effects on Earth.
