We propose to use XMM-Newton to pin down the nature of the newly discoveredINTEGRAL transient IGR J17331-2406. Following the announcement of the discoveryof the source, we triggered our Target of Opportunity programme with the NordicOptical Telescope and obtained images in the U, B, V, R and i filters over twoconsecutive nights, with an additional third night during the following week.However, the INTEGRAL error circle is 2., and as the source is towards theGalactic Centre, there are thousands of potential counterparts. With XMM-Newtonwe propose to identify X-ray sources within the INTEGRAL error circle andcorrelate them with viable counterparts in our NOT images. In addition,XMM-Newton will provide crucial clues to the soft X-ray nature of IGR J17331-2406 which is still unknown.

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.
