S. Golenetskii, R. Aptekar, V. Pal'shin, D. Frederiks,
D. Svinkin, and T. Cline on behalf of the Konus-Wind team, and

A. von Kienlin, X. Zhang, A. Rau, V. Savchenko, E. Bozzo, and C.
Ferrigno, on behalf of the INTEGRAL SPI-ACS GRB team, report:

The long-duration GRB 130610B has been observed by Konus-Wind, INTEGRAL 
(SPI-ACS), and MESSENGER (GRNS), so far, at about 76880 s UT (21:21:20).

We have triangulated it to a preliminary, 3 sigma error box whose 
coordinates are:
  ---------------------------------------------
   RA(2000), deg                 Dec(2000), deg
  ---------------------------------------------
  Center:
   176.359 (11h 45m 26s) -32.187 (-32d 11' 12")
  Corners:
   176.728 (11h 46m 55s) -31.962 (-31d 57' 43")
   176.012 (11h 44m 03s) -32.983 (-32d 58' 58")
   175.989 (11h 43m 57s) -32.409 (-32d 24' 33")
   176.709 (11h 46m 50s) -31.377 (-31d 22' 36")
  ---------------------------------------------
The error box area is 0.37 sq. deg, and its maximum dimension is
1.71 deg (the minimum one is 0.31 deg).

This box may be improved.

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