The NA60 experiment has measured the production of muon pairs and charged particles in In+In collisions at a beam energy of 158 A GeV. For invariant dimuon masses below the φ, the spacetime averaged ρ spectral function was isolated by a novel procedure. It shows a strong broadening but essentially no shift in mass. The production of J/ψ was measured as a function of the collision centrality. As in previous experiments studying Pb+Pb collisions an anomalous suppression is observed, setting in at approximately 90 participant nucleons. Using the charged particles, the reaction plane was reconstructed. The elliptic flow of charged particles increases with pt showing a saturation for pt > 2 GeV/c. For the first time, azimuthal distributions for J/ψ are shown.
