We calculated the color-octet contribution to the double spin asymmetry of$J/\psi$ hadroproduction with nonzero transverse momenta at fixed targetenergies $\sqrt{s}\simeq40$ GeV. It is shown that the color-octet contributionis dominant in the asymmetries. The expected asymmetries and statistical errorsin a future option of HERA with longitudinally polarized protons at HERA-$\vecN$ should allow one to distinguish between different parametrizations for thepolarized gluon distribution in the proton.Comment: 14 pages with 6 figures (epsfig), LaTeX; Some figures are changed and  misprint is correcte
