Solar flares are giant explosions on the sun that send energy, light and high speed particles into space. These flares are often associated with solar magnetic storms known as coronal mass ejections (CMEs). The number of solar flares increases approximately every 11 years, and the sun is currently moving towards another solar maximum, likely in 2013. That means more flares will be coming, some small and some big enough to send their radiation all the way to Earth.
The biggest flares are known as “X-class flares” based on a classification system that divides solar flares according to their strength. The smallest ones are A-class (near background levels), followed by B, C, M and X. Similar to the Richter scale for earthquakes, each letter represents a 10-fold increase in energy output. So an X is ten times an M and 100 times a C. Within each letter class there is a finer scale from 1 to 9.

Who freaking cares?
Didn’t you get the memo from NASA, JayWill? The one that says they were very much wrong about the sun’s maximum, the one that turned out to be such a dud.
NASA did a panel in November 2012 that admitted that the sun is abnormally quiet and the sun is nothing to worry about.
What is the matter? Too many negative comments on your many Planet X or Nibiru stories? Going to fear monger about the sun when it means NOTHING instead?
