From time to time, tremendous explosions on the Sun known as solar flares happen and are classified as X-ray class B, C. M, or X according to their X-ray peak flux. Class B and C are minor flaring events, Class M are moderate, and anything above M6 is consider a major flare. X-class flares are the most powerful.
Note: Currently (16 September 2016) the Sun is very quiet with only a small cluster of three spots (AR 12592) rotating into view. We have passed maximum solar activity several years ago and are well on our way to solar minimum. Never look directly at the Sun without proper eye protection.
