report:

A short-duration GRB 220519A
has been detected by Konus-Wind, INTEGRAL (SPI-ACS),
and Mars-Odyssey (HEND), so far, at about 42339 s UT (11:45:39).

We have triangulated it to a preliminary, 3 sigma error box
whose coordinates are:
 ---------------------------------------------
  RA(2000), deg                 Dec(2000), deg
 ---------------------------------------------
 Center:
  357.784 (23h 51m 08s)  -9.720 ( -9d 43' 11")
 Corners:
  357.477 (23h 49m 54s)  -9.525 ( -9d 31' 30")
  357.634 (23h 50m 32s) -10.012 (-10d 00' 45")
  358.089 (23h 52m 21s)  -9.905 ( -9d 54' 18")
  357.931 (23h 51m 43s)  -9.420 ( -9d 25' 14")
 ---------------------------------------------
The error box area is 843 sq. arcmin, and its maximum
dimension is 43 arcmin (the minimum one is 28 arcmin).
The Sun distance was 65 deg.

This box may be improved.

The time history and spectrum will be given in forthcoming GCN Circulars.
