The surface of the Sun, called the photosphere, is at a temperature of about 5800 K. Sunspots are "cool" regions, only 3800 K (they look dark only by comparison with the surrounding regions). Sunspots can be very large, as much as 50,000 km in diameter. Sunspots are caused by complicated and not very well understood interactions with the Sun's magnetic field.
A small region known as the chromosphere lies above the photosphere

Hi. The surface is covered with Earth sized 'bubbles' of hot gas. http://sohowww.nascom.nasa.gov/data/realtime/realtime-update.html# As your first answer correctly explained, there are sunspots, in addition to prominences, flares, and some pretty dynamic eruptions of other types. This is a cool site! http://science.nasa.gov/headlines/y2007/21mar_chromosphere.htm?list189652
