Abstract

Spectra of sunspots in the region of the lithium 6708 Ǻ line and some FeI and CaI lines have been obtained. The observations were carried out with a CCD-camera on January and August 2011 at the telescope TST-2 of the Crimean Astrophysical Observatory. The sunspot models were calculated using the observed profiles of FeI and CaI lines. The lithium abundance was obtained using the calculated spot models and observed LiI 6708 Ǻ line profiles. The value is log (NLi) = 0.98 and 0.95 (in the scale log A(H) = 12.0).
