  We present 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 - 2018. We also report on our optical spectroscopy at the South
African Astronomical Observatory with the 1.9-m telescope on the night 2018
August 2-3. 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 last
year. After a maximum was reached at the beginning of 2018 July the fluxes in
all bands decreased with some fluctuations. The amplitude of the flux
variability is strongest in the X-ray band and decreases with increasing
wavelength. Low-resolution spectra reveal a dramatic strengthening of the broad
emission as well as high-ionization [FeX]6374 A lines. These lines were not
detected so strongly in the past published spectra. The change in the type of
the optical spectrum was accompanied by a significant change in the X-ray
spectrum. All these facts confirm NGC 1566 to be a changing look Seyfert
galaxy.
