sunspot
This term is used primarily in the context of solar astronomy and astrophysics. It describes a localized region of reduced surface temperature, which appears dark only in contrast to the brighter, hotter surrounding photosphere. It is not a "spot" in the sense of a stain or a pigment, but rather a manifestation of intense magnetic flux.
In a broader scientific context, the term is often linked to the solar cycle. The frequency and distribution of these features are used as primary indicators to track the transition between solar minimum and solar maximum, influencing space weather and satellite communications on Earth.

A sunspot is actually hotter than the surrounding area but appears dark due to the contrast.
I wonder if that sunspot will trigger a solar flare today.
The number of sunspots typically peaks every eleven years.
He spent the afternoon sketching a sunspot for his physics project.
Magnetic fields are the primary cause of a sunspot.
