Abstract Swift-BAT triggered today on several Galactic short bursts (Krimm et al. GCN 8311, 8312), which were claimed to come from a new Soft Gamma Repeater SGR 1550-5418. However, given the positional coincidence of this new putative SGR 1550-5418 with the Anomalous X-ray Pulsar (AXP) 1E1547.0-5408 (Gelfand & Gaensler 2007; Camilo et al. 2008; Halpern et al. 2008), and the enhanced X-ray flux observed from promptly downlinked XRT data of this source (Krimm et al. 8311), we now identify the source of these bursts being the AXP 1E1547.0-5408.
