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.
