The Seyfert Galaxy NGC 1566 was detected in an X-ray outburst by INTEGRAL in June 2018 and triggered several observatories with follow-up observations including the Neil-Gehrels Swift Observatory. This source saw a second, smaller flare in the summer of 2019. I will report on the long and short term X-ray and UV/Optical light curves and how we can explain this outburst by an accretion disk instability. I will also discuss some spectroscopic modeling done with Cloudy. Interestingly, optically NGC 1566 is a 'changing look' AGN which changes its optical spectroscopic classification from a Seyfert 1.5 type to a Seyfert 1. Highresolution X-ray spectroscopy also suggests the presence of outflowing gas with velocities of 500 km/s.
