Eruptive events on the sun can be wildly different. Some come just with a solar flare, some with an additional ejection of solar material called a coronal mass ejection (CME), and some with complex moving structures in association with changes in magnetic field lines that loop up into the sun's atmosphere, the corona.

OMG. Is it the end of the world? Is everyone we love and care about soon to be incinerated by a massive radioactive blast from the sun? Will my iPhone still work?

This image, take by NASA's Solar Dynamics Observatory, is actually a mid-level M-class flare, and one of several that have occurred in the same spot over the past few days. They are harmless and can't pass through the atmosphere, according to NASA, but stronger flares have been known to affect GPS and communications on Earth.

There was a streak of more intense X-class flares during the last week of October, which the Space Weather Prediction Center is calling "one for the history books."
