Description On May 14, 2008, the Swift-BAT triggered on an X-ray flare from the unidentified ROSAT source 1RXJ173523.7-354013. Following the BAT detection, Swift observed the source with the X-ray Telescope (XRT), starting about 150s after the BAT trigger. A very bright X-ray source has been detected;a factor of about 1000 brighter than the ROSAT flux of 1RXHJ173523.7-354013, and it was displaying a rapid flux fading. In the following months the source reached a rather stable flux but at about 3 times higher than the ROSAT flux. By combining all the available Swift data to date, we found evidence for 41 minutes period in the light curve, which is most likely the binary orbital period. We ask for 30ks XMM pointing in order to unveil the nature of this enigmatic source, and confirm our period determination.

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.
