Abstract	Intermediate-mass black holes (IMBH, virgul10^2-10^5 msun) have been long soughtafter because they are associated with several important astrophysicalprocesses. The best IMBH candidates are hyperluminous off-nuclear X-ray sources(HLXs) with LX>10^41 erg/s, but very few are known. We have identified a new HLXcandidate (LXvirgul10^43 erg/s), at an offset of 11.6 (12 kpc) from the center ofits host galaxy (D_L=247 Mpc). We request a deep (60 ks) XMM-Newton observationof the source in AO17 to measure its flux and spectral evolution while it is inthe decay phase of a prolonged outburst, in order to demonstrate its IMBH natureand confirm our tidal disruption event explanation for the outburst. An HSTorbit is also requested to confirm that our source is in a star cluster.

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.
