Swift/BAT detects a hard X-ray burst from AXP CXOU J164710.2-455216
Abstract
The Burst Alert Telescope (BAT) on Swift has detected a faint outburst from the anomalous X-ray pulsar (magnetar) CXOU J164710.2-455216 in the cluster Westerlund 1 (Campana et al, ATEL #893). This pulse was 20 msec long starting at 01:34:52 UTC Sep. 21, 2006 and shows a FRED profile. The best fit position is RA, Dec 251.749, -45.918 (J2000), +/- 3 arcmin (radius, sys+stat, 90% containment). The Chandra position of the AXP is just outside the error circle, at 3.3 arc minutes from the best position.
