%X An angular analysis of the decay B0→ K*0mu+mu- is performed on a data set from LHCb Run 1 corresponding to a total integrated luminosity of 3 fb-1. A complete set of CP-averaged angular observables and their correlations are determined simultaneously in intervals of the dimuon invariant mass squared, q². Special care is taken to separate the two contributions in which the kaon and the pion either originate from a spin 1 or a spin 0 resonance.    The measurement reveals a good agreement with Standard Model predictions. However, observables S5 and S6s show small discrepancies with respect to the predictions in the q² region 1-6 GeV². The measurement is also performed in a second angular basis, confirming a previously observed local deviation in one of its observables, P'5. The agreement between the measurement of P'5 and predictions in the q² region 0.1-8 GeV² corresponds to a p-value of 8.2 10^-4 only. The observations are compatible with theoretical models which predict additional physics contributions at the TeV scale.
