Swift observation of the AXP CXO J164710.2-455216 after a burst
Abstract
Swift performed a TOO observation of the anomalous X-ray pulsar (magnetar) CXO J164710.2-455216 in the cluster Westerlund 1 (Muno et al. 2006, ApJ 636 L41) following the burst detected by the BAT (Krimm et al., GCN 5581). This observation started Sep 21 2006, 14:30:02 UT, i.e. 12.4 hr after the BAT event. In the first dump of data (2.9 ks) we detect a bright source (about 0.6 c/s) at a position RA(2000) = 16 47 10.53 Dec (2000)=-45 52 14.3 with an error box of 3.6 arcsec (90% confidence, throughout the text).
