Abstract	AGN can be obscured by gas streams close to the black hole that shield remoteregions from ionising radiation. We witnessed such an event in NGC 5548 and NGC3783 where 90% of the soft X-rays are blocked by a dense gas stream close to theBLR. Our joint observations with XMM-Newton, NuSTAR and HST/COS showed UV broadabsorption lines associated with the X-ray absorption and allowed us tocharacterise this unique obscuration event completely. We propose to investigatea similar event in another Seyfert 1 using the same instruments. Swiftmonitoring (98 ks) will be used to find the event, which will be characterisedby joint ToO observations with XMM-Newton (150 ks), HST/COS (4 orbits) andNuSTAR (50 ks).

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.
