The discovery of transient Anomalous X-ray Pulsars (AXPs) and outbursts from known AXPs has opened a new perspective in the magnetars field. This proposal is aimed at gathering new insights on the physics of magnetars through the study of the multi-band spectrum of the initial phase of their outbursts. We ask for one 200 ks ToO INTEGRAL observation to be triggered within 10 days following a X--ray flux increase (> than a factor of 10) from a sample of known AXPs and from possible new sources. This observation is aimed at discovering (or study the variability) of the hard X-ray emissionduring magnetars outburst activity. [truncated! Please see actual data for full text]
