We present cross sections for e+e-→hadrons, e+e-, and μ+μ- near 3095 MeV. The ψ(3095) resonance is established as having an assignment JPC=1 - . The mass is 3095 ±4 MeV. The partial width to electrons is Γe=4.8±0.6 keV and the total width Γ=69±15 keV. Total rates and interference measurements for the lepton channels are in accord with μ-e universality.
