A. von Kienlin, G. Lichti, and A. Rau, 
on behalf of the INTEGRAL SPI-ACS GRB team, report:

Mars Odyssey (GRS) also observed this burst (GCN 2221Not found
 
 
, 2222Not found
 
 
).

We have triangulated it to a  preliminary, 3 sigma error box  
with approximate area 124 square arcminutes whose coordinates are:


    RA(2000)                 DEC(2000)
ERROR BOX CENTER:  5 h 14 m 49.82 s     11 o  8 '  16.84 "  (CENTER)
ERROR BOX CORNER 1:  5 h 14 m 18.14 s     11 o 17 '  52.48 "  (CORNER)
ERROR BOX CORNER 2:  5 h 16 m 46.58 s     10 o 25 '  53.82 "  (CORNER)
ERROR BOX CORNER 3:  5 h 12 m 55.74 s     11 o 49 '  57.16 "  (CORNER)
ERROR BOX CORNER 4:  5 h 15 m 21.64 s     10 o 58 '  38.79 "  (CORNER)

This error box may be improved.
