Swift/XRT observations of an outburst of the SFXT IGRJ17544-2619
Abstract
Swift 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 it on 2009 June 06 at 07:48:59 UT (image trigger=354221). Swift immediately slewed to the target, so that the NFIs started observing about 164s after the trigger. The initial Swift/XRT data (WT mode, 170-446 s since the trigger) show a decaying light curve with a count rate that started at about 20 counts/s.
