SGR1935+2154 is the latest discovered member of the rapidly increasing class ofmagnetars and has been discovered due to its transient behaviour and theemission of short and intense (F_X > 10 Crabs) bursts. We have inferred theperiod of the source (3.2s) while the first period derivative is stillundetected preventing us to infer its main parameters. Moreover, unexpectedly wefound a diffuse emission component around the pulsar. This nebula might beeither the second strongest candidate for the elusive magnetar wind Nebula or adust- scattering halo. We request two pointings of 40 and 60ks aimed at: i)inferring the main pulsar parameters, ii) monitoring its decay, iii) looking forits quiescent state, and carry out a detailed study of the extended emission.

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.
