team, report:

The long bright GRB 100701B, seen by Fermi/GBM (Foley, GCN 10920), has 
also been detected by INTEGRAL (SPI-ACS), Suzaku (WAM),  Konus-Wind, and 
MESSENGER (GRNS) so far.

We have triangulated it to a 3 sigma error box whose coordinates are:
-----------------------------------------------
    RA(2000), deg              Dec(2000), deg
-----------------------------------------------
Center:
   43.109 (02h 52m 26s)    -2.224 (-02d 13' 25")
Corners:
   43.260 (02h 53m 02s)    -2.497 (-02d 29' 49")
   43.081 (02h 52m 19s)    -2.310 (-02d 18' 36")
   42.959 (02h 51m 50s)    -1.947 (-01d 56' 50")
   43.138 (02h 52m 33s)    -2.137 (-02d 08' 14")

-----------------------------------------------

The error box area is 149.7 sq. arcmin.
This error box may be improved.

The GBM position (Foley, GCN 10920) is 2.7 deg from the center of the box.
