Strange formation is a sun spot and fairly common.The number on the surface correlates with how active the sun is . Spots occur when magnetic fields causes surface temperature to reduce , making a section stand out . Have temperature of up to 4,200°C ( 7,590°F ) , compared to 5,500°C ( 9,930°F ) of the surrounding solar material . Gordon Ewen captured the unique photograph using a large telescope at the bottom of his garden in Letchworth .
