Abstract	We propose a deep 200 ks NuSTAR observations of the nearby (z = 0.005) repeatchanging-look AGN NGC 1566 as it returns to quiescence, simultaneous with a 10ks XMM-Newton exposure, to complete the X-ray picture of this unique source.With this observation, we will follow the properties of the X-ray corona as thesource transitions back to a Seyfert 2, combining this with Swift monitoring totrack the evolution of the accretion disk.

Mission Description	The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
