TITLE: GCN CIRCULAR NUMBER: 1432 SUBJECT: SGR-like Bursts from the AXP 1E 2259+586 DATE: 02/06/19 15:32:56 GMT FROM: Peter Woods at UAH/MSFC Bursts from the Anomalous X-ray Pulsar 1E 2259+586 V. M. Kaspi (McGill University/MIT), F. P. Gavriil (McGill University) and P. M. Woods (USRA/NSSTC) report: We have detected several short X-ray bursts from the direction of the anomalous X-ray pulsar 1E 2259+586, using the PCA aboard RXTE. The bursting behavior was detected during a routine 15-ks duration monitoring observation which began June 18, 2002 at 15:39 UTC. In this observation, ~45 bursts were detected, most of which had duration < 1-2 sec, reminiscent of those seen in soft gamma repeaters. The mean 1-s flux per burst is approximately 10{^-8} erg/cm^2/s (2-20 keV). The Chandra-determined position for this pulsar is J2000 RA 23 01 08.295, DEC +58 52 44.45 (uncertainty 0".60 in radius, 99% confidence; Hulleman et al. 2001, ApJ, 563, L49). Observations at other wavebands are encouraged.
