Rau, on behalf of the Fermi GBM team, report:\n\nGRB 130228A was detected by the Fermi GBM (trigger 383712005),\nKonus-Wind, RHESSI, Suzaku WAM, Swift BAT (outside the coded FoV),\nand MESSENGER GRNS.  We have triangulated it to a preliminary,\n3 sigma error box whose coordinates are:\n\n\n      \t      RA(2000)\t\t\t      Dec(2000)\nCenter:  256.8792 = 17 h 07 m 31 s\t+57.9767 = 57 d 58 m 36 s\nCorners: 257.9210 = 17 h 11 m 41 s\t+74.5340 = 74 d 32 m 03 s\n         256.9529 = 17 h 07 m 49 s      +36.0592 = 36 d 03 m 33 s\n         255.7015 = 17 h 02 m 48 s      +76.3736 = 76 d 22 m 25 s\n         256.3030 = 17 h 05 m 13 s      +38.7303 = 38 d 43 m 49 s\n\nand whose area is 22.7 sq. deg.  This error box may be improved.\n\nThe minimum distance between the edge of the error box and the\nedge of the 0.5 degree radius LAT error circle (Zheng and Akerlof,\nGCN 14258) is about 1.5 arcminutes.  Thus the two localizations\nare consistent if the LAT error circle radius is a roughly one\nsigma confidence region.\n\nMaps have been posted at ssl.berkeley.edu/ipn3/130228.",
