- Abstract
A spectrum of a sunspot in the range of the Li I λ 670.8 nm line and some lines of Ca I, Ti I, Al I, and Na I was measured. Observations were carried out with the TST-2 telescope of the Crimean astrophysical observatory on August 21, 1981. A model of the spot was calculated from the observed profiles of the Ca I, Ti I, Al I, and Na I lines. From the calculated model and the observed profile of the Li I λ 670.8 nm line, the lithium abundance was estimated as log( N) = 0.78 (in the scale of log A(H)= 12.0).
