team, report:

The long bright GRB 100707A, observed by Fermi/GBM at 00:46:38.99 UT 
(Wilson-Hodge & Foley, GCN 10944Not found
 
 
) and Fermi/LAT (Pelassa & 
Pesce-Rollins, GCN 10945Not found
 
 
), has also  been detected by Suzaku (WAM), 
Konus-Wind, and MESSENGER (GRNS) so far.

We have triangulated it to a preliminary 3 sigma error box whose 
coordinates are:
-----------------------------------------------
    RA(2000), deg              Dec(2000), deg
-----------------------------------------------
Center:
  358.019 (23h 52m 05s)    -8.658 (-08d 39' 29")
Corners:
  358.562 (23h 54m 15s)   -11.226 (-11d 13' 32")
  358.773 (23h 55m 05s)   -11.654 (-11d 39' 14")
  357.369 (23h 49m 29s)    -5.832 (-05d 49' 56")
  357.116 (23h 48m 28s)    -5.295 (-05d 17' 42")
-----------------------------------------------

The error box area is 0.660 sq. deg
This error box may be improved.

The GBM position (Wilson-Hodge & Foley, GCN 10944Not found
 
 
) is 7.2 deg from the 
center of the box.
