dc.descriptionSingle Spin Asymmetries (SSA) $A_N$ measured in the two reactions at the Protvino 70 GeV accelerator are presented. $A_N$ in the reaction $p+p(pol)->π^0+X$ in the central region is close to zero within the error bars. SSA in the reaction $π^- +p(pol)->π^0+X$ in the polarized target fragmentation region is equal to $(-15 \pm 4)%$ at $|x_F|>0.4$. There is an indication that the asymmetry arises at the same pion energy in the center of mass system.
