The period of the Maunder minimum (1645–1715) is well known due to the observations of astronomers at the Paris Observatory: Picard, father and son La Hire, Cassini and their students. Thanks to their drawings of the solar disk, we know the pattern of the spatio-temporal distribution of sunspots from 1670 to 1719. As we digitize and analyze the historical drawings of sunspots made by other observers during the Maunder minimum, we have a unique opportunity to supplement the catalog of Hoyt and Schatten and compare the observations of Parisian astronomers with those of their contemporaries. We present the results of reconstructing the parameters of solar activity from the archives of Georg Christoph Eimmart.
