  In 2015 the calculation of the International (Zurich) sunspot number was
cancelled, and it was replaced by a new "recalibrated" series. A new data
series was proposed also for the Group sunspot number. As a result, these two
series which originally differed mainly in their long-term trends, were
"reconciled", and the long-term trends in both of them were minimized. These
changes led to new reconstructions of the long-term variations of solar
irradiance, and to reconsidering the impact of the solar activity variations on
climate change. Here we use data for the number of sunspots and the number of
sunspot groups from a single observatory with continuous and homogeneous
observations in order to evaluate how justified these recalibrations are.
