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.

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