Sunspots

The blemishes you see here on the photosphere of the sun are called sunspots. They are dark, because they're relatively colder and darker than the places around it. These phenomena move about the photosphere, and can die out at any time. A few days to a few months are the most common times, though. Concentrations of magnetic field flux cause these spots to occur.

Prominence

A prominence is a large, bright, gaseous feature extending from the photosphere, usually in a loop shape. They are anchored to the photosphere, and extend outwards to the corona. These can last for a few years, at most.

Solar Flare

Solar flares occur when magnetic energy in the sun's atmosphere that has built up over the years is suddenly released. The energy released is in the form of accelerated and heated particles. These are the largest explosions that have happened in our solar system. Flares on other suns can be 1000 times more powerful, and last more than a week.

Aurora

An aurora is a natural light display in the sky usually seen near the poles. They appear when the magnetosphere is disturbed by solar winds from the sun. They appear in Earth's thermosphere and exosphere.
