team, report:

The long, bright GRB 100826A, observed by the Fermi/LAT and Fermi/GBM at 
22:58:22.89 UT (McEnery & Omodei, GCN 11155Loading...
 
 ), was also detected by 
Konus-Wind, Mars Odyssey (HEND), MESSENGER (GRNS), and Suzaku (WAM).

We have triangulated it to a preliminary 3 sigma error box whose
coordinates are:
-----------------------------------------------
     RA(2000), deg              Dec(2000), deg
-----------------------------------------------
Center:
  279.593 (18h 38m 22s)   -22.128 (-22d 07' 42")
Corners:
  279.356 (18h 37m 25s)   -20.511 (-20d 30' 38")
  279.424 (18h 37m 42s)   -18.324 (-18d 19' 27")
  279.708 (18h 38m 50s)   -25.604 (-25d 36' 13")
  280.041 (18h 40m 10s)   -26.935 (-26d 56' 07") 
-----------------------------------------------

The error box area is ~1.5 sq. deg
This error box may be improved.
