We identify some features as likely being He II 4686, H beta, He I 5876, and H alpha in emission. All lines have FWHM of ~12,000 km/s. Using a distance modulus of 34.4 mag to the host galaxy and correcting for MW extinction, the discovery magnitude corresponds to M = -18.5 mag, similar to other TDEs, but more luminous than most SNe II. From the confirmation image, the transient appears coincident with the nucleus of its host galaxy. ATel 11865
