A Detailed Reconstruction of Solar Activity During the Maunder Minimum

Besides its decadal modulation, the solar cycle presents long-term secular changes in the amplitude of adjacent cycles that drive long-term changes in the heliospheric environment and have been suggested to drive long-term changes in terrestrial seasonal weather. The best well known of these secular changes is the Maunder Minimum (1645-1715), which coincided with an interval of very cold winters in Europe. Unfortunately, this period is characterized by a significant lack of telescopic observations and thus suffers from a very high level of observational uncertainty. In this presentation we will discuss recent efforts to increase the observational reliability of observations during the Maunder Minimum, by taking advantage of observational redundance, the analysis of these observations to place strict constraints on solar activity during the Maunder Minimum, by comparing with modern observations, and the implications these results have for our understanding of the solar dynamo.
