TL;DR: In this article, the authors revisited all existing evidence and datasets, both direct and indirect, to assess the level of solar activity during the Maunder minimum, and concluded that solar activity was indeed at an exceptionally low level during this period.

TL;DR: In this paper, a revised collection of the number of sunspot groups from 1610 to the present is presented, based on the work of Hoyt and Schatten (Solar Phys. 179, 189, 1998).

TL;DR: In this article, the authors revisited all the existing pieces of evidence and datasets, both direct and indirect, to assess the level of solar activity during the Maunder minimum, and concluded that solar activity was indeed at an exceptionally low level during this period.

TL;DR: In this paper, the results of an international numerical benchmark study based on two-dimensional axisymmetric mean field solar dynamo models in spherical geometry are presented, which can help in further development and validation of numerical codes that solve such problems.

TL;DR: Using the newly recovered solar drawings by the 18-19th century observers Staudacher and Hamilton, the authors constructed the solar butterfly diagram, i.e., the latitudinal distribution of sunspots in the 1790s.
