The paper discussed briefly the occurrence of auroras and comets and variations in the strength of the solar wind, during the period of 1645 to 1715, often termed as the “Maunder-Minimum” because of the perceived quietness of the Sun during this period. However, a more careful examination of all the available observations of these phenomena reveals regular cyclic activity of the Sun throughout this interval.
