Abstract	We have discovered a BH recoil candidate offset by 800 pc from a nearby dwarfgalaxy. The object, SDSS1133, shows offset broad lines and strong variability.While originally classified as a supernova because of its non-detection in 2005,we detect it in observations over 63 years. Using high-resolution AO, weconstrain the emission region to be <12 pc. We request a 24 ks XMM observationto decide whether this is a recoiling black hole or an unprecedented 50 yearoutbursting LBV star (e.g. Eta Carina) followed by a unique long duration SN IInwith rebrightening. SDSS1133 has recently undergone a 1.3 mag rebrightening inPanSTARRS imaging that is unprecedented for a late time SN (>10 yr) and suggeststhat the coming year is a critical time to observe this faint source at maximum.

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.
