Description We have discovered an increasing but highly variable X-ray activity in the direction of a small, but optically extended, object that we believe to be a galaxy at redshift about 0.45. Analysis to within the limits of the current data suggest that the X-ray activity is most likely due to the tidal disruption of a giant star with a long rising phase by the supermassive black hole within the galaxy. Confirmation of such an event would be unprecedented and indicate a new class of high-energy outbursts. We propose to have a joint monitoring of such a rare event with XMM-Newton and Swift immediately, which is required to measure the energetics and understand the physics behind the extreme environment of such an event.

Mission Description The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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.
