D. Svinkin, and T. Cline on behalf of the Konus-Wind team,

K. Hurley, and J. Goldsten, on behalf of the MESSENGER NS GRB team,

S. Barthelmy, J. Cummings, N. Gehrels, H. Krimm, and D. Palmer, on
behalf of the Swift-BAT team, and

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 short-duration, hard, intense GRB 111113A has been observed by 
INTEGRAL (SPI-ACS), Konus-Wind, MESSENGER (GRNS), and Swift (BAT) 
(outside the coded field of view) so far, at about 18618 s UT (05:10:18).
We have triangulated it to a preliminary, 3 sigma error box whose 
coordinates are:
  ---------------------------------------------
   RA(2000), deg                 Dec(2000), deg
  ---------------------------------------------
  Center:
   225.390 (15h 01m 34s)  +2.185 ( +2d 11' 05")
  Corners:
   224.649 (14h 58m 36s)  +1.899 ( +1d 53' 57")
   225.195 (15h 00m 47s)  +2.382 ( +2d 22' 56")
   226.104 (15h 04m 25s)  +2.430 ( +2d 25' 47")
   225.583 (15h 02m 20s)  +1.985 ( +1d 59' 05")
  ---------------------------------------------

The error box area is 1408 sq. arcmin, and its maximum dimension is 93 
arcmin.

This box can be improved.

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