Description	We report on optical absorption and EPR spectroscopy studies of low Er doped (50 ppm) SrTiO3 single crystals. In the region of 400–650 nm a set of optical intra-configurational f–f transitions from the 4I15/2 ground state to the excited 4F9/2, 4S3/2, 2H11/2, and 2H9/2 Stark sublevels of the Er3+ impurity ions were observed and identified. At T=2K the number of registered optical transitions evidences the presence of only one type of Er3+ centers with non-cubic symmetry. The system of the energy levels for Er3+ excited states is determined. The X-band EPR spectra at 5.2 K revealed the rhombic symmetry of Er impurity centers. The components of a rhombic g-tensor were defined. It was suggested that Er ions substitute Sr ions in A-sublattice sites.
