on behalf of the GRS-Odyssey GRB team, report:

The bright long-duration GRB 160802A has been detected by
Fermi (GBM: Bissaldi, GCN Circ. 19754), Konus-Wind, Mars-Odyssey (HEND),
and INTEGRAL (SPI-ACS), so far, at about 22410 s UT (06:13:30).

We have triangulated it to a preliminary, 3 sigma error box whose
coordinates are:
 ---------------------------------------------
  RA(2000), deg                 Dec(2000), deg
 ---------------------------------------------
 Center:
   28.027 (01h 52m 07s) +71.370 (+71d 22' 10")
 Corners:
   26.646 (01h 46m 35s) +71.433 (+71d 26' 00")
   28.172 (01h 52m 41s) +71.786 (+71d 47' 09")
   29.401 (01h 57m 36s) +71.295 (+71d 17' 41")
   27.891 (01h 51m 34s) +70.952 (+70d 57' 08")
 ---------------------------------------------
The error box area is 1343 sq. arcmin, and its maximum
dimension is 53 arcmin (the minimum one is 36 arcmin).
The Sun distance was about 78 deg.

This box may be improved.

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