Sunspots are darker areas that can be seen on the surface of the Sun if projected on to a piece of card through a telescope.
How they are caused?
They are caused by the regions of the Sun’s visible surface becoming trapped in twisted areas of magnetic fields. The numbers of sunspots varies over an eleven-year cycle.
Sunspots are associated with other events on the sun, such as solar flares, when vast amounts of high-energy particles are ejected from the sun. If these head towards the earth , they can bump into the earth’s magnetic field.
Dark patches present in the photosphere on the surface of the Sun. Temperatures in the dark centers of sunspots drop to about 3700 K compared to 5700 K
