Scientific paper

The Swift satellite has observed a new outburst from IGR J17544-2619, a Supergiant Fast X-ray Transient discovered in September 2003 with INTEGRAL (Sunyaev et al., ATel#190). The Swift Burst Alert Telescope (BAT) triggered on March 31 at 20:50:45 UT, (trigger=308224). Swift immediately slewed to the target, so that the NFI onboard Swift started observing it about 162s after the trigger. The BAT mask-weighted light curve shows a long lasting plateau emission from about T-107 s to T+553 s, with an approximately 8 s long peak centered at 546 s.
