Zehnder, on behalf of the RHESSI GRB team, and A. von Kienlin, G. Lichti, and A. Rau, on behalf of the INTEGRAL SPI-ACS GRB team, report: This event (GCN 1870) was also observed by Mars Odyssey and RHESSI. We have triangulated it to a preliminary, 3 sigma error box with approximate area 68 square arcminutes whose coordinates are: RA(2000) DEC(2000) ERROR BOX CENTER: 12 h 26 m 22.80 s -11 o 51 ' 24.23 " ERROR BOX CORNER 1: 12 h 26 m 30.37 s -11 o 53 ' 08.09 " ERROR BOX CORNER 2: 12 h 25 m 27.01 s -11 o 56 ' 50.21 " ERROR BOX CORNER 3: 12 h 27 m 18.75 s -11 o 45 ' 54.28 " ERROR BOX CORNER 4: 12 h 26 m 15.24 s -11 o 49 ' 40.33 " This error box may be improved.
