The short-duration GRB 240205A
(Ferm-GBM detection: The Fermi GBM team, GCN 35679;
Glowbug detection: Cheung, et al.,  GCN 35707)
was detected by Fermi (GBM trigger 728857595), Konus-Wind,
INTEGRAL (SPI-ACS), and Swift (BAT) at about 73591 s UT (20:26:31).
The burst was outside the coded field of view of the BAT.

We have triangulated this GRB to the following annuli:
annulus          R.A.     Dec.     R     dR (3sigma)
                (deg)    (deg)   (deg)     (deg)
Konus-GBM     297.778  -19.219  40.665  0.735
GBM-SPI-ACS   180.960   84.546  70.289  6.208
The annuli intersect to form a long 60.9 sq.deg (3 sigma)
localization region.

This localization may be improved.

A triangulation map and HEALPix FITS file are posted at

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