Abstract: We present results of recent optical spectroscopic variability campaigns for HE 1136-2304 and NGC 1566 which exhibited X-ray outbursts in July 2014 and June 2018, respectively. We show that the broad line region (BLR) structure in the changing-look AGN HE 1136-2304 is similar to that of non-changing-look AGN and that the BLR kinematics is dominated by Keplerian accretion disk (AD) rotation. Furthermore, we present an optical spectrum of NGC 1566 taken only a few weeks after its X-ray outburst, clearly showing drastic spectral changes.
