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

The short-duration 200815A
(CALET-GBM detection: Kobayashi et al., GCN Circ. 28255)
has been detected by Konus-Wind, INTEGRAL (SPI-ACS),
Mars-Odyssey (HEND), and Swift (BAT), so far,
at about 75764 s UT (21:02:44).
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
   356.686 (23h 46m 45s) -27.798 (-27d 47' 54")
   356.902 (23h 47m 36s) -27.811 (-27d 48' 41")
   356.836 (23h 47m 21s) -28.066 (-28d 03' 58")
   356.471 (23h 45m 53s) -27.785 (-27d 47' 05")
   356.536 (23h 46m 09s) -27.528 (-27d 31' 39")
The error box area is 357 sq. arcmin, and its maximum
dimension is 36 arcmin (the minimum one is 7 arcmin).
The Sun distance was 148 deg.

This box may be improved.

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