On 2006 September 21, the candidate AXP CXOUJ1647 entered in an outburst phase.Since then XMM has monitored the decay of CXOUJ1647 allowing us to study itsspectral and timing properties and their evolution. Until the latestobservation, the timing and spectral parameters were evolving and smoothlyapproaching the 2006 pre-outburst values. However, the latest observationsuggested that either the spectral model used for the quiescent emission iswrong or the 2006 bursting activity has modified the emission properties ofCXOUJ1647. This proposal is aimed at completing the XMM monitoring of CXOUJ1647and studying and comparing the spectral/timing parameters as it approaches toits (new) quiescent state with those of the previous quiescence state.

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.
