Abstract	We have recently discovered the first SGR with a low magnetic field (Rea et al.2010, Science, 330, 944), SGR 0418+5729, discovered in outburst after it emittedbursts similar to those of magnetars (B<7.5x10^{12} G). This discovery had largeimplications not only for the magnetar model, but for the pulsars population ingeneral. We have now a tentative measure (at 2.8sigma level) of its periodderivative resulting in a B-field =7.1x10^{12} G). We ask now for a final 75ksXMM observation to confirm this detection at >5sigma. This will lead to have afinal measure of SGR 0418+5729 dipolar magnetic field, crucial for tuning themagnetar model as well as predict how many hidden magnetars there might bewithin the pulsar population.

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.
