D. Svinkin, D. Frederiks, A. Lysenko, A. Ridnaia,
and T. Cline on behalf of the Konus-Wind team,

and

A. Goldstein, M. S. Briggs, C. Wilson-Hodge,
and E. Burns on behalf of the Fermi-GBM team, report:

The short-duration GRB 261025B
(Fermi-GBM detection: The Fermi GBM team, GCN 46029)
was detected by Fermi (GBM trigger 814642716) and
Konus-Wind at about 63512 s UT (17:38:32).

We have triangulated it to the 3 sigma localization region
whose area is 45.7 sq. deg, and its maximum
dimension is 43 deg (the minimum one is 1.1 deg).

This localization may be improved.

A triangulation map and HEALPix FITS files are posted at
http://www.ioffe.ru/LEA/GRBs/GRB261025_T63508/IPN/
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.
