Definitions for "Sunspots"
Sunspots are cool, dark patches on the Sun's surface. They are caused by disturbances in the sun's magnetic field which make the sunspot about 2700°F (1500°C) cooler than the surrounding area. Sunspots occur where the sun's magnetic field loops up out of the solar surface. The number of sunspots follows an 11-year solar cycle; the current cycle had already peaked in late March 2001 where there was a really big solar flare. Sunspots are visible from Earth. (WARNING: do NOT look at the sun; it can damage your eyes permanently!)
These are temporary areas of magnetic field concentration on the Sun's photosphere (the visible surface of the Sun). In these areas the magnetic concentration prevents the heat from the core of the Sun escaping to the surface, which results in the area being cooler. This is why these areas appear darker in the images.
Temporary magnetic disturbances in the photosphere. They appear dark because temperatures are considerably lower than in surrounding areas. More about sunspots...
In economics, sunspots (sometimes a sunspot) usually refers to an extrinsic random variable, that is, a random variable that does not directly affect economic fundamentals (endowments, preferences, and and technology). “Sunspots” can also refer to the related concept of extrinsic uncertainty, economic uncertainty that does not come from variations in economic fundamentals.
