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

A short-duration GRB 160702A has been detected by Konus-Wind, INTEGRAL
(SPI-ACS), Mars-Odyssey(HEND), and Swift (BAT) at about 44544 s UT
(12:22:24). 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:
  230.889 (15h 23m 33s)  +8.715 ( +8d 42' 54")
 Corners:
  231.265 (15h 25m 03s)  +9.181 ( +9d 10' 51")
  230.871 (15h 23m 29s)  +9.187 ( +9d 11' 15")
  230.515 (15h 22m 04s)  +8.245 ( +8d 14' 41")
  230.908 (15h 23m 38s)  +8.243 ( +8d 14' 33")
 ---------------------------------------------
The error box area is 1320 sq. arcsin, and its maximum
dimension is 1.194 deg (the minimum one is 22 arcmin).
The Sun distance was about 121 deg.

This box may be improved.

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