Hello Monica A solar flare is a rapid release of energy from a localized region on the Sun in the form of electromagnetic radiation, energetic particles, and mass motions. A coronal hole is an area of the corona which appears dark in X-rays and ultraviolet light. They are usually located at the poles of the Sun, but can occur other places as well. The magnetic field lines in a coronal hole extend out into the solar wind rather than coming back down to the Sun's surface as they do in other parts of the Sun. An aurora is an event which occurs when the atmospheric molecules discussed above are excited by incoming charged particles from the solar wind. They emit energy as they fall back to their ground state. Auroras generally occur at high latitudes, near the Northern and Southern magnetic poles. The chance of seeing an aurora has been shown to rise and fall with the number of visible sunspots. These spots were first observed by Galileo and have since then been shown to increase and decrease in number over an eleven year period.
