As a result, the energy flux from the Sun's interior decreases, and with it, surface temperature, causing the surface area through which the magnetic field passes to look dark against the bright background of photospheric granules. Sunspots initially appear in the photosphere as small darkened spots lacking a penumbra.
A black spot on the sun struck me as being a very painful image, and I felt that was my soul up there on the sun. It's just projecting your state into the world of symbolism, which is what poetry's all about, really."
Apelles is wrong to say that sunspots are much darker than dark spots on the Moon; the spots are in fact not as dark as the area immediately around the Sun which is most strongly illuminated by it, and this area is itself so bright that the Moon would be invisible if we tried to observe it in that position.

Sunspots are relatively dark areas on the Sun's radiating 'surface' (photosphere) where intense magnetic activity inhibits convection and cools the Photosphere. Faculae are slightly brighter areas that form around sunspot groups as the flow of energy to the photosphere is re-established and both the normal flow and the sunspot-blocked energy ...
A coronal hole at the Sun's north pole observed in soft X-ray. Coronal hole size and population correspond with the solar cycle. As the Sun heads toward solar maximum, the coronal holes move closer and closer to the Sun's poles. [4] During solar maxima, the number of coronal holes decreases until the magnetic fields on the Sun reverse.
Sometimes, that happens unevenly, which produces spots or patches of pigmentation, like sun spots. People tend to notice sun spots starting in their 20s and 30s, Lamb says, and they become more ...
These appear as dark spots on the Sun's surface, known as sunspots. Thus, sunspots tend to occur under coronal loops, and tend to come in pairs of opposite magnetic polarity ; a point where the magnetic field loop emerges from the photosphere is a North magnetic pole , and the other where the loop enters the surface again is a South magnetic pole.
