and A. Goldstein, on behalf of the Fermi GBM team, and

W. Boynton, C. Fellows, K. Harshman, H. Enos, and R. Starr,
on behalf of the GRS-Odyssey GRB team, report:

The long-duration GRB 171119A was detected by
Fermi (GBM trigger 532828112), Konus-Wind, INTEGRAL (SPI-ACS),
and Mars-Odyssey (HEND) at about 85707 s UT (23:48:27).

We have triangulated it to a preliminary, 3 sigma error box whose 
coordinates are:
  ---------------------------------------------
   RA(2000), deg                 Dec(2000), deg
  ---------------------------------------------
  Center:
   135.318 (09h 01m 16s) -50.281 (-50d 16' 53")
  Corners:
   136.349 (09h 05m 24s) -52.250 (-52d 14' 59")
   134.356 (08h 57m 26s) -48.624 (-48d 37' 25")
   134.404 (08h 57m 37s) -48.273 (-48d 16' 21")
   136.374 (09h 05m 30s) -51.905 (-51d 54' 19")
  ---------------------------------------------
The error box area is 1893 sq. arcmin, and its maximum
dimension is 4.17 deg (the minimum one is 8.2 arcmin).
The Sun distance was 80 deg.

This box may be improved.

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