Salotti (ASI), on behalf of the AGILE Team, report: "A bright burst from AXP 1E 1547.0-5408 / SGR J1550-5418 was triggered and imaged by SuperAGILE on 22 March 2009, at 22:39:16 UT. The event had a duration of about 250 ms, with a multi-peak structure. The peak flux on the 10 ms timescale was approximately 3.6e-5 erg/cm2/s in the 20-60 keV energy range, based on the raw assumption of a Crab-like energy spectrum. The latest reported bursting activity from this source dates back to 2009, Feb 24th (Kouveliotou et al., GCN #8915)."
