Abstract: The ATLAS detector at CERN-s LHC is preparing to take data from the firstproton-proton collisions expected in the next few months. We report on theanalysis of simulated data samples for production of heavy Quarkonium statesJ-psi and Upsilon, corresponding to an integrated luminosity of 10 pb^-1 withcenter of mass energy of 14 TeV expected at the early ATLAS data. We reviewvarious aspects of prompt Quarkonium production at LHC: the accessible rangesin transverse momentum and pseudorapidity, spin alignment of vector states,separation of color octet and color singlet production mechanism andfeasibility of observing radiative decays Xi c and Xi b decays. Strategies ofvarious measurements are outlined and methods of separating promptly producedJ-psi and Upsilon mesons from various backgrounds are discussed.
