behalf of the GRS-Odyssey GRB team, report:

The long-duration, very bright GRB 141104A has been observed by Swift 
(BAT), Konus-Wind, Mars Odyssey (HEND), MESSENGER (GRNS), and  INTEGRAL 
(SPI-ACS), so far, at about 200 s UT (00:03:20). The burst was outside 
the coded field of view of the BAT.

We have triangulated it to a preliminary, 3 sigma error box whose 
coordinates are:
  ---------------------------------------------
   RA(2000), deg                 Dec(2000), deg
  ---------------------------------------------
  Center:
   279.488 (18h 37m 57s) -12.702 (-12d 42' 07")
  Corners:
   279.368 (18h 37m 28s) -12.296 (-12d 17' 45")
   279.549 (18h 38m 12s) -12.326 (-12d 19' 32")
   279.607 (18h 38m 26s) -13.111 (-13d 06' 38")
   279.426 (18h 37m 42s) -13.078 (-13d 04' 41")
  ---------------------------------------------
The error box area is 492 sq. arcmin, and its maximum
dimension is 51 arcmin (the minimum one is 10 arcmin).
The Sun distance was 58.5 deg.

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