Level and length of cyclic solar activity during the Maunder minimum as deduced from the active day statistics
J. M. Vaquero, G. A. Kovaltsov, I. G. Usoskin +2
The Maunder minimum (MM) of greatly reduced solar activity took place in 1645-1715, but the exact level of sunspot activity is uncertain as based, to a large extent, on historical…
