A plage is a bright region in the chromosphere of the Sun, typically found near sunspots. Think of it as a solar beach ποΈ, a bit brighter and more active than its surroundings. Plages indicate areas of increased density and temperature in the Sun's atmosphere. They're like the sun's way of flexing its muscles πͺ. These regions are associated with the emergence of magnetic flux. They can last from a few hours to several days. Imagine them as the sun's version of a heatwave π₯.
