Sunspots are phenomena on the Sun's photosphere that appear as temporary spots that are darker than the surrounding areas. They are regions of reduced surface temperature caused by concentrations of magnetic flux that inhibit convection. Sunspots appear within active regions, usually in pairs of opposite magnetic polarity. Their number varies according to the approximately 11-year solar …

WebSep 8, 2024 · A sunspot has mainly two portions which are umbra, penumbra, and there is another external part which is spicules. The temperature of umbra is 4300 K which is cooler than the surface of sun, and this difference is the cause of being dark of sunspots. Sunspot cycle is basically periodic 11-year solar magnetic activity cycle.
Sunspot numbers over the past 11,400 years have been reconstructed using carbon-14 isotope ratios. The level of solar activity beginning in the 1940s is exceptional – the last period of similar magnitude occurred around 9,000 years ago (during the warm Boreal period).
