Sunspot Umbra ~3,500 - 4,000 The dark, central core of the sunspot. This layer has a temperature of approximately 5,500 degrees Celsius at its base, cooling as it extends outward.
Identifying Sunspots in the Photosphere Layer
Impact on Solar Activity. Comparing Temperatures and Brightness The temperature of the photosphere averages around 5,500°C, but the central region of a sunspot, known as the umbra, is significantly cooler, dropping to about 3,500°C to 4,000°C.
It is the opaque layer that prevents us from seeing deeper into the solar interior. The Solar Atmosphere Structure The Sun is composed of several distinct layers, each with unique properties and dynamics.
Identifying Sunspots in the Photosphere Layer
The Lifecycle of a Sunspot Sunspots are not permanent fixtures; they are dynamic regions that evolve over time. This magnetic energy is generated by the motion of charged particles in the plasma.
