Goldsten, on behalf of the MESSENGER NS GRB team, and E. Costa, E. Del Monte, I. Donnarumma, Y. Evangelista, M. Feroci, I. Lapshov, F. Lazzarotto, L. Pacciani, M. Rapisarda, P. Soffitta, for the SuperAGILE team, report: GRB110815A at 34857 s UT was detected by SuperAGILE (outside the coded FoV), Konus-Wind, MESSENGER GRNS, Odyssey HEND, RHESSI, Suzaku WAM, and Swift BAT (also outside the coded FoV). We have triangulated it to a preliminary, 3 sigma error box whose area is 195 sq. arcmin and whose coordinates are: RA(2000) DEC(2000) 85.297 o = 5 h 41 m 11.2 s +32.442 = 32 o 26 ' 31 " (CENTER) 85.183 o = 5 h 40 m 43.9 s +32.409 = 32 o 24 ' 31 " (CORNER) 85.464 o = 5 h 41 m 51.3 s +32.753 = 32 o 45 ' 12 " (CORNER) 85.130 o = 5 h 40 m 31.1 s +32.113 = 32 o 06 ' 48 " (CORNER) 85.411 o = 5 h 41 m 38.6 s +32.474 = 32 o 28 ' 26 " (CORNER) A map has been posted at ssl.berkeley.edu/ipn3/110815. This error box can be improved. The time history and spectrum will be given in a forthcoming GCN Circular. A Swift ToO has been requested.
