The revival of solar activity after Maunder minimum in reports and observations of E. Manfredi

We present information, published here for the first time, concerning observations of sunspots made at the beginning of the XVIIIth century. The information has been taken from specola's archives in Bologna. It concerns the years just after the end of the Maunder minimum. The data confirms the presence of a double maximum in 1704–1707, and shows a high asymmetry in sunspots latitude distribution, possibly related to the abnormal Sun activity in the second half of XVIIth century.
