  journal={Solar Physics},
Measurements of 10Be concentration in the Dye 3 ice core show that magnetic cycles persisted throughout the Maunder Minimum, although the Sun's overall activity was drastically reduced and sunspots virtually disappeared. Thus the dates of maxima and minima can now be reliably estimated. Similar behaviour is shown by a nonlinear dynamo model, which predicts that, after a grand minimum, the Sun's toroidal field may switch from being antisymmetric to being symmetric about the equator. The presence… Expand

The extension of sunspot number series and auroral observations backward in time is of considerable interest for dynamo theory, solar activity and climate research. It was known that the MaunderExpand
Solar cycles during the Maunder minimum
We have obtained new consistent versions of the 400-yr time series of the Wolf sunspot number W, the sunspot group number G, and the total sunspot area S (or the total sunspot magnetic flux Φ). WeExpand
Sunspot and Auroral Activity During Maunder Minimum
The extremely low sunspot activity during the period of the Maunder minimum 1645–1715 was confirmed by group sunspot numbers, a new sunspot index constructed by Hoyt and Schatten (1998a,b). NeitherExpand
Intense Geomagnetic Storm during Maunder Minimum Possibly by a Quiescent Filament Eruption
The sun occasionally undergoes the so-called grand minima, in which its magnetic activity, measured by the number of sunspots, is suppressed for decades. The most prominent grand minima, since theExpand
The Maunder Minimum and the Solar Dynamo
Based on archival observations of solar activity, we suggest a scenario for the Maunder minimum, and compare to what extent this is reproduced by dynamo models of Grand minima. In particular, weExpand
A possible explanation of the Maunder minimum from a flux transport dynamo model
We propose that the poloidal field at the end of the last sunspot cycle before the Maunder minimum fell to a very low value due to fluctuations in the Babcock-Leighton process. With this assumption,Expand

Modeling the Sun's Large-Scale Magnetic Field during the Maunder Minimum
We use a flux transport model to simulate the evolution of the Sun’s magnetic dipole moment, polar fields, and open flux under Maunder minimum conditions. Even when the rate of active regionExpand
Solar cyclicity during the Maunder minimum
A multifaceted statistical study of all available data on solar activity during the Maunder minimum (1645–1715) is presented. The data include European telescope observations, Asian sunspotExpand
Erratum to: The Maunder Minimum and the Sun as the Possible Source of Particles Creating Increased Abundance of the 14C Carbon Isotope
The Maunder Minimum was the time during the second part of the 17th century, nominally from 1645 to 1717 AD, when unusually low numbers of sunspots were observed. On the basis of numerous recordedExpand


Estimating the Sun's radiative output during the Maunder Minimum
The coincidence between the Maunder Minimum of solar magnetic activity from 1645 to 1715 and the coldest temperatures of the Little Ice Age raises the question of possible solar forcing of theExpand
The solar sunspot cycle in the Maunder minimum AD 1645 to AD 1715
We present a unique collection of quantitative sunspot observations recorded at the Observatoire de Paris from 1660- 1719. These data contrast significantly with that of earlier observers whoExpand
Use of 10Be in polar ice to trace the 11-year cycle of solar activity
A DETAILED knowledge of the history of solar magnetic activity is important in several respects. From satellite data there is increasing evidence that solar magnetic activity and solar irradiance areExpand
Stellar Luminosity Variations and Global Warming
The levels of solar activity required for this to occur are not observed in carbon-14 and beryllium-10 records over the past several millennia, which indicates that such an increase in amplitude of surface magnetism-driven variations in solar luminosity is unlikely in the present epoch. Expand
How well was the Sun observed during the Maunder Minimum?
In this paper we examine how well the Sun and sunspots were observed during the Maunder Minimum from 1645 to 1715. Recent research has given us the dates of observations by Hevelius, Picard, La Hire,Expand

Long-term solar brightness changes estimated from a survey of Sun-like stars
THE brightness of the Sun varies during the 11-year solar cycle, typically by less than 0.1% (refs 1, 2), and a larger brightness variation is thought to have occurred during the Maunder minimum,Expand
