XMM-Newton observations of Seyfert galaxies established outbursts of radio-quietAGNs as a still poorly explored discovery space for AGN physics with an enormouspotential to learn\: NGC 1566, HE1136-2304 and NGC 2617 are rare and extremechanging-look AGNs tracing rapid changes in accretion and/or corona physicsincluding the launching of new outflows. GSN 069 very likely traces an AGNdisturbed by a tidal disruption event. We propose two 80ks simultaneousXMM-Newton(EPIC\RGS)/NuSTAR observations accompanied by optical spectroscopy ofthe next suited AGN outburst(s). They will allow tracing the accretion physics,the launching of winds and outflows, the spectral complexity connected withdramatic emission-line changes and possibly the elusive tidal disruption events.

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.
