-
Sunspots: Dark spots that are visible on the surface of the sun that are caused by intense magnetic activity that disrupts convection forming areas of reduced surface temperatures.
-
Solar Flare: A magnetic storm on the Sun which is a very hot, bright spot that usually occurs near sunspots; an explosion that releases huge amounts of high-energy particles and gases and are ejected thousands of miles from the surface of the sun.
-

-
Aurorae: These are visible effects of the Sun's activity on Earth's atmosphere. It results from the interaction of the solar wind, a continuous flow of electrically charged particles with gases in the upper atmosphere of the Earth at altitudes above 50 miles.
