GBM team, report:

GRB 140810A (Moretti et al. GCN 16678, Golenetskii et al. GCN 16679,
Roberts et al. GCN 16680) has been observed by Odyssey-HEND, MESSENGER
GRNS, Konus-Wind, INTEGRAL SPI-ACS, and Fermi GBM and LAT, so far.  We
have triangulated it to a preliminary, 3 sigma error box whose
coordinates are:

  ---------------------------------------------
   RA(2000), deg                 Dec(2000), deg
  ---------------------------------------------
  Center:
   119.056 (07h 56m 13s) +27.413 (+27d 24' 47")
  Corners:
   119.076 (07h 56m 18s) +28.016 (+28d 00' 58")
   119.014 (07h 56m 04s) +26.723 (+26d 43' 23")
   119.470 (07h 57m 53s) +28.814 (+28d 48' 49")
   118.462 (07h 53m 51s) +25.183 (+25d 10' 57")
  ---------------------------------------------
The error box area is 1450  sq. arcmin., and its maximum/minimum
dimensions are 3.74/0.096 deg. 

This error box is consistent with the Fermi-LAT 90% confidence,
statistical-only error circle (GCN 16678), and constrains it slightly.
A map has been posted at ssl.berkeley.edu/ipn3/140810A.  This
localization may be improved.
