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.
