Abstract On September 2006 an intense (10^39 ergs) and short (20ms) burst was detected bySwift from the candidate Anomalous X-ray Pulsar CXOU J164710.2-455216. A Swiftobservations carried out 13 hours later found that the AXP entered in a rareoutburst phase and measured a flux level 300 times brighter then that inquiescence. Subsequent Swift, Chandra, XMM and SUZAKU follow-up observationsmonitored the initial phases of the source outburst allowing to infer veryimportant information for this source. Both the spectral and timing propertiesof CXOU J164710.2-455216 drastically changed and are still evolving after oneyear. The present proposal is aimed at following the evolution of the mainspectral/timing parameters of the second confirmed bursting transient AXP.

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.
