The litium abundance in sunspots
The observations of lithium were carried out with TST-2 at the Crimean observatory on August 15–20, 2006. The spot model for observation dates was estimated. The lithium abundance in a sunspot and in the undisturbed photosphere was detected. It equals Lg(NLi) = 1.35. for the sunspot and Lg(NLi) = 1.05 for the undisturbed photosphere.
