Y. Terada, T. Murakami, and K. Makishima on behalf of the Suzaku WAM
team, report:

The long-duration, intense GRB 120707A (Younes, GCN 13422) has been 
observed by Fermi (GBM: trigger 363381140), Konus-Wind, INTEGRAL 
(SPI-ACS), Swift (BAT), Mars Odyssey (HEND), and Suzaku (WAM), so far, 
at about 69140 s UT (19:12:20). The burst was outside the coded field of 
view of the BAT.

We have triangulated it to a preliminary, 3 sigma error box whose 
coordinates are:
  ---------------------------------------------
   RA(2000), deg                 Dec(2000), deg
  ---------------------------------------------
  Center:
   291.874 (19h 27m 30s) -32.770 (-32d 46' 12")
  Corners:
   293.104 (19h 32m 25s) -36.566 (-36d 33' 56")
   292.808 (19h 31m 14s) -37.093 (-37d 05' 36")
   290.585 (19h 22m 20s) -27.663 (-27d 39' 48")
   290.769 (19h 23m 05s) -26.473 (-26d 28' 23")
  ---------------------------------------------

The error box area is 3.50 sq. deg, and its maximum dimension is 10.8 deg.
This box can be improved.
