report:
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.
