report:

The short-duration GRB 241022A was detected by
Konus-Wind, INTEGRAL (SPI-ACS), Swift (BAT),
and Mars-Odyssey (HEND) at about 79703 s UT (22:08:23).
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:
    0.480 (00h 01m 55s) +31.665 (+31d 39' 53")
 Corners:
    1.971 (00h 07m 53s) +29.734 (+29d 44' 02")
  359.012 (23h 56m 03s) +33.596 (+33d 35' 47")
  359.001 (23h 56m 00s) +33.460 (+33d 27' 35")
    1.968 (00h 07m 52s) +29.579 (+29d 34' 43")
 ---------------------------------------------
The error box area is 1401 sq. arcmin, and its maximum
dimension is 4.74 deg (the minimum one is 5 arcmin).
The Sun distance was 146 deg.

This localization may be improved.
