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

A short-duration GRB 160806A has been detected by Fermi (GBM),
Konus-Wind, INTEGRAL (SPI-ACS), Mars-Odyssey (HEND), and Swift (BAT)
at about 50460 s UT (14:01:00). 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:
  274.477 (18h 17m 54s) +10.607 (+10d 36' 25")
 Corners:
  275.105 (18h 20m 25s) +10.412 (+10d 24' 42")
  274.010 (18h 16m 02s) +11.481 (+11d 28' 52")
  273.846 (18h 15m 23s) +10.795 (+10d 47' 42")
  274.941 (18h 19m 46s)  +9.712 ( +9d 42' 45")
 ---------------------------------------------
The error box area is 3308 sq. arcmin, and its maximum
dimension is 1.99 deg (the minimum one is 36 arcmin).
The Sun distance was about 130 deg.

This box may be improved.

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