Scientific paper

INTEGRAL performed a ToO observation on the AXP 1E1547.0-5408, triggered by the intense outbursts detected on 2009-01-22 (GCN 8837, 8834, 8833). The still ongoing INTEGRAL observation started at 2009-01-24T15:31 and will last for 100 ks. Within the first 80 ks of the observation, the AXP is detected by IBIS/ISGRI with 14.6 sigma significance and a flux of 9.8±0.7 mCrab (20-40 keV). The 20-150 keV spectrum can be fit by a simple power law model with photon index 1.8±0.2 and a model flux of f(20-150 keV) = 2.6e-10 erg/cm**2/sec.
