D. Svinkin, and T. Cline on behalf of the Konus-Wind team,

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

G. Di Cocco, F. Fuschino, M. Galli, C. Labanti, and M. Marisaldi, on
behalf of the AGILE MCAL team, report:

The long-duration, very bright GRB 130320A has been observed by 
Konus-Wind, INTEGRAL (SPI-ACS), MESSENGER (GRNS), and AGILE (MCAL), so 
far, at about 25720 s UT (07:08:40).

We have triangulated it to a preliminary, 3 sigma error box whose
coordinates are:
  ---------------------------------------------
   RA(2000), deg                 Dec(2000), deg
  ---------------------------------------------
  Center:
   192.684 (12h 50m 44s) -14.471 (-14d 28' 15")
  Corners:
   190.889 (12h 43m 33s) -17.026 (-17d 01' 34")
   190.945 (12h 43m 47s) -17.088 (-17d 05' 15")
   195.164 (13h 00m 39s) -10.078 (-10d 04' 40")
   195.128 (13h 00m 31s)  -9.967 ( -9d 58' 00")
  ---------------------------------------------
The error box area is 0.646 sq. deg, and its maximum dimension is
8.2 deg (the minimum one is 5 arcmin).

This box may be improved.

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