We summarize a study of optical, UV and X-ray light curves of the nearby changing look active galactic nucleus in the galaxy NGC 1566 obtained with the Neil Gehrels Swift Observatory and the MASTER Global Robotic Network over the period 2007-2019. We also report on optical spectroscopy using the South African Astronomical Observatory 1.9-m telescope between Aug. 2018 (Oknyansky et. al 2018, 2019) and Mar. 2019. A substantial increase in X-ray flux by 1.5 orders of magnitude was observed following the brightening in the UV and optical bands during the first half of 2018 year (Kuin et. al 2018, Ferrigno et al. 2018, Grupe et al. 2018a, Kein 2018, Oknyansky et al. 2019, Parker et al. 2019). After a maximum was reached at the beginning of July 2018, the fluxes in all bands decreased with some fluctuations (see Event1 and Event2 at the Fig.2 and Grupe et al. 2018b, 2019). The amplitude of the flux variability is strongest in the X-ray band and decreases with increasing wavelength. Low-resolution spectra (2 Aug. 2018) reveal a dramatic strengthening of the broad emission as well as high-ionization [FeX]6374 lines. These lines were not detected so strongly in the past published spectra. The change in the type of the optical spectrum (Oknyansky et al. 2018, 2019) was accompanied by a significant change in the X-ray spectrum. For the last spectra (30 Nov. 2018 -- 28 Mar. 2019) we see dramatic changes compared to Aug 2018, accompanied by the fading of broad emission lines. Effectively, two changing look (CL) cases were observed by us for this object during past year.
