Abstract
The paper describes the first reconstruction of the annual values of the total area and magnetic flux of sunspots, as well as the Wolf index, on the 2000-year time scale. The procedure was performed by combining data on solar cyclicity amplitudes obtained from a decadal reconstruction (Usoskin et al., 2014) and data on its phases acquired from the numbers of auroras, which is contained in catalogs by Křivský and Silverman.
