On 2008 October 3rd, Swift-BAT triggered on several short bursts from the direction of the Anomalous X-ray Pulsar (AXP) 1E1547.0-5408 (Krimm et al. GCN 8311, 8312; Rea et al. Atel #1756). This is the second known transient radio AXP discovered to date (Gelfand & Gaensler 2007; Camilo et al. 2007), and it showed the previous X-ray outburst around June 2007 (Halpern et al. 2008). During the decay of the 2007 X-ray outburst we observed 1E 1547.0-5408 in the Ks band (on 2007 July 8th, 12th, and August 17th) with the NAOS -CONICA (NACO) instrument mounted at the ESO- VLT (Mignani, Rea, Testa, et al., 2008 submitted).
