We request an INTEGRAL ToO on Anomalous X-ray Pulsar (AXP) 4U 0142+61now that it is has exhibited an large burst with characteristics of aSoft Gamma-ray Repeater giant flare. This large burst has beenobserved in RXTE monitoring data (Gavriil et al 2007 Atel 993) andshows a bright brief peak (peak flux 4E-8 erg/s/cm2 2-60 keV) and along (20--30 mins) tail where the pulsars oscillations arevisible. The burst profile (not the fluence) resembles the SGR giantflare of SGR 1806-20 of December 27 2004 (e.g. Borkowski et al 2006GCN 2920 Palmer et al 2006 Hurley et al 2006). Such a burst hasnever been observed for an AXP before. [truncated! Please see actual data for full text]
