Solar flares are created by the sun. They are large amounts of energy escaping out into space in the form of a beautiful stream of energy. A Corona, I believe is the halo of light that surrounds the sun when you look at it. You can see the corona during an eclipse. I'm not an expert on this, but those are just some answers.
