A. von Kienlin, X. Zhang, A. Rau, V. Savchenko, E. Bozzo, and C.
Ferrigno, on behalf of the INTEGRAL SPI-ACS GRB team, report:

The long-duration, moderately intense GRB 120919B was observed by Fermi
(GBM: trigger 369710066), Konus-Wind, MESSENGER (GRNS), INTEGRAL
(SPI-ACS), and Mars Odyssey (HEND) at about 4463 s UT (01:14:23).

We have triangulated it to a preliminary, 3 sigma error box whose
coordinates are:
   ---------------------------------------------
    RA(2000), deg                 Dec(2000), deg
   ---------------------------------------------
   Center:
    302.633 (20h 10m 32s) -37.490 (-37d 29' 25")
   Corners:
    302.735 (20h 10m 56s) -37.483 (-37d 28' 59")
    302.857 (20h 11m 26s) -38.235 (-38d 14' 04")
    302.530 (20h 10m 07s) -37.497 (-37d 29' 50")
    302.401 (20h 09m 36s) -36.706 (-36d 42' 21")
   ---------------------------------------------
The error box area is 457  sq. arcmin, and its maximum
dimension is 1.57 deg (the minimum one is 10 arcmin).

This box can be improved.
