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

The long-duration, bright GRB 120522A has been observed by Konus-Wind, 
MESSENGER (GRNS), and Mars Odyssey (HEND), so far, at about 11467 s UT 
(03:11:07).

We have triangulated it to a preliminary, 3 sigma error box whose
coordinates are:
  ---------------------------------------------
   RA(2000), deg                 Dec(2000), deg
  ---------------------------------------------
  Center:
   165.996 (11h 03m 59s) -62.094 (-62d 05' 37")
  Corners:
   165.772 (11h 03m 05s) -61.976 (-61d 58' 35")
   165.879 (11h 03m 31s) -62.218 (-62d 13' 06")
   166.222 (11h 04m 53s) -62.211 (-62d 12' 38")
   166.112 (11h 04m 27s) -61.969 (-61d 58' 08")
  ---------------------------------------------
The error box area is 141 sq. arcmin, and its maximum
dimension is 19 arcmin. The Sun distance is ~116 deg.

This box may be improved.

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