W. Boynton, C. Fellows, K. Harshman, H. Enos, and R. Starr,
on behalf of the GRS-Odyssey GRB team, report:

The long-duration GRB 180526A (Sharma et al., GCN Circ. 22742)
was detected by Konus-Wind, INTEGRAL (SPI-ACS), Mars-Odyssey (HEND),
and AstroSat (CZTI) at about 39814 s UT (11:03:34).

We have triangulated it to a preliminary, 3 sigma error box whose
coordinates are:
   RA(2000), deg                 Dec(2000), deg
   108.576 (07h 14m 18s)  +3.677 ( +3d 40' 36")
   109.188 (07h 16m 45s)  +3.834 ( +3d 50' 02")
   108.877 (07h 15m 31s)  +2.756 ( +2d 45' 23")
   107.965 (07h 11m 52s)  +3.525 ( +3d 31' 31")
   108.274 (07h 13m 06s)  +4.632 ( +4d 37' 57")
The error box area is 1.2 sq. deg, and its maximum
dimension is 1.97 deg (the minimum one is 1 deg).
The Sun distance was 47 deg.

This box may be improved.

A triangulation map is posted at

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