Our Sun is near its peak activity in a 11 year cycle, and recently aurorae were visible on Long Island. Why does this happen? And what happens if a more energetic stream of particles from the Sun were to hit earth? In this lecture, we'll discuss the Sun's magnetic activity, its quiet and active phases, and look at some historical solar outbursts that have impacted Earth.
