report:

The long-duration GRB 260706B was detected by Konus-Wind,
Psyche (GRNS), Mars-Odyssey (HEND), and BepiColombo (MGNS)
at about 84082 s UT (23:21:22).

We have triangulated it to a preliminary, 3 sigma error box
whose coordinates are:
 ---------------------------------------------
  RA(2000), deg                 Dec(2000), deg
 ---------------------------------------------
 Center:
  130.509 (08h 42m 02s) +16.967 (+16d 58' 00")
 Corners:
  130.752 (08h 43m 01s) +17.921 (+17d 55' 14")
  130.743 (08h 42m 58s) +17.692 (+17d 41' 30")
  130.183 (08h 40m 44s) +15.751 (+15d 45' 04")
  130.232 (08h 40m 56s) +16.102 (+16d 06' 06")
 ---------------------------------------------
The error box area is 352 sq. arcmin, and its maximum
dimension is 2.2 deg (the minimum one is 3 arcmin).
The Sun distance was 24 deg.

This localization may be improved, as soon as the Psyche (GRNS) timing accuracy will be analyzed.

A triangulation map and HEALPix FITS files are posted at

The HEALPix triangulation map is the multi-order HEALPix in units of
probability density.

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