report:

The short-duration GRB 260617A
(Fermi-GBM detection: Fermi GBM team, GCN 44969;
Godwin & Meegan, GCN 44972)
was detected by Fermi (GBM trigger 803425008), Konus-Wind,
and Mars-Odyssey (HEND) at about 77803 s UT (21:36:43).

We have triangulated it to the 3 sigma localization region
whose area is 3360 sq. arcmin, and its maximum
dimension is 4.4 deg (the minimum one is 12.9 arcmin).

A triangulation map and HEALPix FITS files are posted at
http://www.ioffe.ru/LEA/GRBs/GRB260617_T77808/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.
