Swift observations of a bright outburst of the SFXT IGR J17544-2619
Abstract
The Swift Burst Alert Telescope (BAT) triggered on a new outburst from the Supergiant Fast X-ray Transient (SFXT) IGR J17544-2619 on 2010 March 04 at 23:13:54 UT (image trigger=414875). Swift immediately slewed to the target, so that the narrow field instruments started observing about 395 s after the trigger. Using the BAT data set from T-119 to T+183 sec we see a broad peak of approximate duration 150 seconds starting from ~T-50 relative to the start of the image trigger.
