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, intense GRB 111205A has been observed by
INTEGRAL (SPI-ACS), Konus-Wind, and Mars Odyssey (HEND) so far, at about 
47450 s UT (13:10:50).
We have triangulated it to a preliminary, 3 sigma error box whose 
coordinates are:
   RA(2000), deg                 Dec(2000), deg
   134.486 (08h 57m 57s) -31.972 (-31d 58' 20")
   134.668 (08h 58m 40s) -32.260 (-32d 15' 37")
   134.190 (08h 56m 46s) -31.944 (-31d 56' 38")
   134.306 (08h 57m 13s) -31.682 (-31d 40' 57")
   134.782 (08h 59m 08s) -31.999 (-31d 59' 57")

The error box area is 492 sq. arcmin, and its maximum
dimension is 39 arcmin.

This box can be improved.

The time history and spectrum will be given in a forthcoming GCN Circular.

A Swift ToO observation has been requested.
