WebSunspots are dark, planet-sized regions that appear on the surface of the Sun. They are caused by twisting, chaotic magnetic fields from within the Sun’s convective zone.These powerful magnetic disturbances produce active regions on the Sun, which can often create solar flares and coronal mass ejections (CMEs).

Why Low Sunspot Activity Portends Prolonged Climate Chill
WebJan 22, 2024 · The April 22, 2024 Jupiter/Neptune conjunction, for instance, corresponds to the 2024 low in sunspot numbers. Although certain planetary cycles have corresponded with sunspot cycles in a remarkably close fashion, a few out-of-step periods appear in the record. The last time this occurred was between 1770 and 1800. WebApr 26, 2024 · Generally, sunspot reports from observatories calculate sunspot numbers whereby each sunspot group counts as 10, and every umbra within each spot group is individually considered as 1. Therefore, no sunspots on the visible Sun would be considered as zero; while the next possible number can only be 11 or higher. spirit lamp chemistry
