Recent X-ray observations of the two Seyfert galaxies, GSN 069 and NGC 2617,establish outbursts of radio-quiet AGNs as an unexplored discovery space for AGNphysics with an enormous potential to learn. We propose three joint XMM-Newton /NuSTAR observations (start, maximum and 1/e) of the next suited AGN outburstwhereas an X-ray/optical/UV light curve will be established with short Swiftobservations. True AGN outbursts will allow us to trace accretion physics, X-rayspectral complexity connected with dramatic emission-line changes and possiblyelusive stellar tidal disruption events probing an even more extreme accretionregime. We will identify outbursts mainly based on Swift, XMM-Newton slew andGaia observations.

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.
