The Sun may appear smooth and brilliant. But often is scattered with dark spots. Sunspots are areas that appear dark on the surface of the Sun. They appear dark because they are cooler than other parts of the Sun’s surface, about 6500 degrees. Solar flares are a sudden explosion of energy caused by tangling, crossing or reorganizing of magnetic field lines near sunspots.
It is possible to catch them with a normal camera but (VERY IMPORTANT!!!) with an Energy Rejection filter that reduces the energy of the sun light. If you point the camera directly to the Sun serious injuries may occur to the eyes and of course to the camera!
