Where do we see sunspots ?
Sunspots Sunspots are dark spots on the surface of sun, which are 2,000 degrees centigrade❗❗but cooler than the rest of the surface of sun . The coolest bit of the sunspots is the dark center called umbra . There is the penumbra around it . Some sunspots appear as mere specks on the sun's surface . They also appear in groups , which can be ten times the size of the earth❗❗😱😱 . Sometimes they measure 200,000 miles in length .
