Around July 11 (45 days prior to this writing) a sunspot was seen.
Almost 80% of 2009 has had no sunspots visible.
We call them sunspots, but dark and cool are relative terms. A sunspot is dark only relative to the surrounding solar surface, but still intensely bright compared to your common household light bulb. It's cooler than the surrounding solar material, but still hot enough to vaporize a spaceship and anyone inside it in a fraction of a second.
Dark spots on the Sun are called sunspots. (You knew that was coming, didn't you?)
Dark spots that appear on the surface of the sun are called sunspots. They are areas of reduced temperature caused by interactions with the sun's magnetic field.
They are sun spots. Sun spots are cooler than the rest of the sun. They have strong magnetic field and usually occur in groups or in pairs. When they are in pairs one sun spot usually means the north pole of a magnet while the other means the south. Sun spots can sometimes be bigger than earth. The eleven year cycle of sunspots is the number of sunspots increasing and decreasing again. Hope that answered all your questions about sun spots.
The scientific name is a "parhelion". It's when there are bright spots in rings (formed by ice crystals) around the Sun in the sky. It's not seen too often, but usually it's seen best just before sunset. Sometimes it's called a "mock Sun" and I think that gives a better idea of what the phenomenon looks like.

Sunspots are areas that are cooler.
Sunspots are dark spots visible on the sun that are caused by intense magnetic activity and causes the area where the sunspots are seen to cool the temperature at that area.

sun spots are cooler parts of the sun
the sun spots like black little spots on the sun that explode every 11 years
Saturn may or may not have Saturn spots. Only the sun has sun spots.

Sun spots are not permanent, therefore it depends.
Sunspots. Do not look at the sun directly. You will be blinded. Answer 2: They are called Sun's dark spots. The new study reports that Sun's dark spots seem to form when uranium fission lifts away a large chunk of Sun's core material along with fission fragments into nuclear fallout. A large crater formed at the site of fission appears as Sun's dark spot since no emission takes place from the site, while the remaining Sun's disk show very low intensity at Bharat Radiation, UV and visible light wavelengths.
Sometimes they can be bigger that earth. I have seen some numbers on the internet:50,000 km85,000 kmSomewhere in that range
