In addition to a historical overview and general information, major advances
and problems of solar paleoastrophysics are described, including the data obtained by
means of cosmogenic isotopes (14C, 10Be), nitrates (NO3- ion), and historical observations.
The most recent proxy-based paleoreconstructions of sunspot numbers and sunspot
area, covering time intervals from 150 to 10 000 years, are presented. Possible sources
of time variations of the concentration of 14C, 10Be and NO3- ion in terrestrial archives
are considered.
