We investigate the pattern of asymmetries in the colour-octet model forinclusive production of charmonium with polarised initial state hadrons andphotons. We find that singly polarised asymmetries vanish. The double polarisedasymmetry for J/psi involves a new combination of long-distance matrix element.We also investigate the asymmetries for eta_c, chi_c and Upsilon production.The asymmetries distinguish well between different models of charmoniumproduction.Comment: LaTeX source, 18 page
