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

K. Hurley and J. Goldsten, on behalf of the MESSENGER NS GRB team,

G. Di Cocco, F. Fuschino, M. Galli, C. Labanti, and M. Marisaldi, on
behalf of the AGILE MCAL 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 short-duration, hard spectrum, bright GRB 140604A has been observed
by Konus-Wind, AGILE (MCAL), MESSENGER (GRNS), and INTEGRAL (SPI-ACS),
so far, at about 17411 s UT (04:50:11).

We have triangulated it to a preliminary, 3 sigma error box whose 
coordinates are:
---------------------------------------------
    RA(2000), deg                 Dec(2000), deg
   ---------------------------------------------
   Center:
    263.170 (17h 32m 41s) -40.406 (-40d 24' 22")
   Corners:
    262.578 (17h 30m 19s) -40.773 (-40d 46' 24")
    263.162 (17h 32m 39s) -41.034 (-41d 02' 02")
    263.750 (17h 35m 00s) -40.031 (-40d 01' 53")
    263.172 (17h 32m 41s) -39.770 (-39d 46' 12")
   ---------------------------------------------
The error box area is 2020 sq. arcmin, and its maximum
dimension is 76 arcmin (the minimum one is 31 arcmin).

This box may be improved.

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