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

A short-duration GRB 150919A has been detected by Konus-Wind,
INTEGRAL (SPI-ACS), and Mars-Odyssey (HEND), so far,
at about 74595 s UT (20:43:15).

We have triangulated it to a preliminary, 3 sigma error box whose 
coordinates are:
   RA(2000), deg                 Dec(2000), deg
   132.960 (08h 51m 50s) +44.066 (+44d 03' 59")
   132.432 (08h 49m 44s) +43.742 (+43d 44' 33")
   132.726 (08h 50m 54s) +44.076 (+44d 04' 34")
   133.487 (08h 53m 57s) +44.379 (+44d 22' 43")
   133.193 (08h 52m 46s) +44.055 (+44d 03' 20")
The error box area is 412 sq. arcmin, and its maximum
dimension is 59 arcmin (the minimum one is 11 arcmin).
The Sun distance was 58 deg.

This box may be improved.

A triangulation map is posted at

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