SuperAGILE detects an X-ray burst from a position consistent with IGR J17473-2721

During the AGILE pointing at the Galactic Center region SuperAGILE detected a burst from the sky position RA=266.842, Dec=-27.339 (error radius 3 arcmin). This position lies approximately 1.1 arcmin from the position of the source IGR J17473-2721 (Grebenev et al., ATel #467) and approximately 1 arcmin from the proposed counterpart detected by Swift/XRT (Kennea et al., ATel #500) and Chandra (Juett et al., ATel #521).
