Abstract
Several observations of some Ap stars have been made at the ESO, Nordi c and Crimean telescopes in 1996. Interesting results have been found for the roAp star HD 83368 = HR 3831 in the Li spectral region. These have shown the presence of two almost diametrically opposed spots of L i or of the element responsible for the ''Li'' blend, which cause stro ng variations in the profile and position of the Li blend at 6708 Angs trom.
