Abstract

The observations of lithium were carried out with the TST-2 telescope at CrAO on August 15–20, 2006. A sunspot model was calculated for the dates of observations. The lithium abundance in a sunspot and in the undisturbed photosphere was determined. It is log(N Li) = 1.35 for the sunspot and log (N Li) = 1.05 for the undisturbed photosphere.
