on behalf of the GRS-Odyssey GRB team, report:
The long-duration GRB 181011A
(MAXI/GSC detection: Kawakubo et al., GCN Circ. 23327)
was detected by Konus-Wind, INTEGRAL (SPI-ACS),
and Mars-Odyssey (HEND) at about 12979 s UT (03:36:19).
We have triangulated it to a preliminary error box
whose coordinates are:
---------------------------------
RA(2000), deg Dec(2000), deg
---------------------------------
Center:
93.1530 19.1552
Corners:
93.2025 23.5555
94.8930 14.2497
94.7356 11.0039
91.9740 23.5347
--------------------------------
The error box area is about 10 sq. deg, and its maximum
dimension is 11.2 deg (the minimum one is 1.1 deg).
The Sun distance was about 171 deg.
This box may be improved.
The box is consistent with the MAXI/GSC localization.
A triangulation map is posted at

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