Introduction

What are sunspots?

A sunspot is a temporary spot on the Sun that appears relatively dark. These spots are caused by magnetic “storms” that prevent convection from distributing heat evenly over the surface of the Sun. This results in relatively cold areas of the Sun. These spots may be as large as fifty thousand miles in diameter, such that they can be visible from Earth even without a telescope (but that doesn’t mean you should look at the Sun).
