How hot are sun spots?
Question Date: 1999-05-27
Answer 1:

I found some info about sunspots on the web at


Here's what I found, in a nutshell: Sun spots typically have a temperature of 3900 degrees Celsius, while the photosphere has a temperature of about 5500 degrees Celsius. The sunspots are thus darker than the rest of the surface of the sun.

Answer 2:

Sun spots are actually cool spots on the surface of the sun that are associated with large magnetic fields. The surface of the sun has a temperature of 5800 Kelvin (what is that in Celsius or Fahrenheit?). A sunspot is typically 1600 Kevlin cooler.

Answer 3:

Sun spots are about 4000 Kelvin or over 7000 degrees Celsius.

Answer 4:

Sun spots are magnetically disturbed areas on the surface of the sun that are actually cooler than the surrounding surface. The temperature of the sun's surface is about 5700 K or 9800 degrees Fahrenheit whereas the temperature of sunspots is closer to 4000-4500 K or 6740-7640 degrees Fahrenheit. Even though sun spots are cooler than other parts of the sun, they are still much hotter than anything on Earth! Why do you think sunspots are darker than the rest of the sun?
