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

A short-duration GRB 160620A was detected by Konus-Wind, Swift (BAT), 
INTEGRAL (SPI-ACS), and Mars-Odyssey (HEND) at about 18373 s UT 
(05:06:13). 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:
    250.662 (16h 42m 39s) +30.321 (+30d 19' 15")
   Corners:
    251.505 (16h 46m 01s) +30.332 (+30d 19' 57")
    250.769 (16h 43m 04s) +30.603 (+30d 36' 11")
    249.821 (16h 39m 17s) +30.298 (+30d 17' 51")
    250.557 (16h 42m 14s) +30.038 (+30d 02' 18")
   ---------------------------------------------
The error box area is 1467 sq. arcmin, and its maximum
dimension is 1.454 deg (the minimum one is 28 arcmin).
The Sun distance was 123 deg.

This box may be improved.

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