Построена зависимость асимметрии солнечной активности от номера 11-летнего цикла на период 1745-2018 гг. Зависимость показывает, что за последние два цикла произошел резкий спад активности Солнца, возможно, предваряющий глубокий минимум.
We have constructed the dependence of asymmetry of sunspot activity upon the number of 11-year cycle for the 1610-2019 years period. This dependence shows the abrupt sunspot fall during two last cycles of solar activity. Presumably this fall appears to be a precursor of a deep minimum.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
