| Abstract | The deep minimum state of AGNs is characterized by a strongly suppressed or evenabsent primary continuum. As the continuum disappears weak spectral featureslike relativistic iron lines or narrow.. soft X-ray emission lines fromionised plasmas become highly significant and their parameters can bedetermined. Therefore deep minimum states offer unique possibilities toinvestigate in detail the physics of the reprocessed components in AGN,including the immediate vicinity of the supermassive black hole. Applying ourexperience (successful trigger of a long deep minimum observation) we proposetwo triggered 10ks-short snapshot observations and one 80ks-long follow-upobservation of an AGN in deep minimum state. We will identify deep minimum states based on Swift and XMM-Newton slew 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. |
