Warwick) report:\n\nWe note that the the error box of the bright short hard GRB 110406A\ndetected by INTEGRAL SPI-ACS and the IPN (GCNs 11890, 11893, 11900)\noverlies NGC 404, a dwarf galaxy at a distance of ~3 Mpc. The IPN\nerror box and the extent of NGC 404 are overlayed on a GALEX FUV image\nhere: http://www.star.le.ac.uk/~bar7/NGC404_FUV.jpg\n\nNGC 404 is a recently rejuvinated lenticular galaxy, forming the\nmajority of its new stars in a ring with a star formation rate of\n2.5e-3 M_sol yr^-1 (Thilker et al., 2010, ApJ, 714, L171).\n\nIf this GRB is associated with NGC 404, the isotropic energy released\nwould be ~6e46 erg (20 keV - 10 MeV) using the Konus-Wind spectral fit\n(GCN 11893) which would be consistent with an SGR giant flare origin,\nwhile the presence of a young stellar population within this galaxy\nwould also be consistent with this model. For comparison, the giant\nflare from SGR 1806-20 had Eiso ~3.7e46 erg (Hurley et al., 2005,\nNature, 434, 1098).",
