S. Barthelmy, J. Cummings, N. Gehrels, H. Krimm, and D. Palmer,
on behalf of the Swift-BAT team, report:

The short-duration, hard-spectrum, bright GRB 141011A (von Kienlin, GCN 
Circ. 16905) has been observed by Fermi (GBM trigger 434702783), 
Konus-Wind, MESSENGER (GRNS), Mars Odyssey (HEND), Swift (BAT), and 
INTEGRAL (SPI-ACS), so far, at about 24380 s UT (06:46:20). 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:
   257.939 (17h 11m 45s)  -9.681 ( -9d 40' 52")
  Corners:
   257.903 (17h 11m 37s)  -9.336 ( -9d 20' 10")
   257.999 (17h 12m 00s)  -9.336 ( -9d 20' 09")
   257.975 (17h 11m 54s) -10.026 (-10d 01' 34")
   257.878 (17h 11m 31s) -10.027 (-10d 01' 36")
  ---------------------------------------------
The error box area is 236 sq. arcmin, and its maximum
dimension is 42 arcmin (the minimum one is 6 arcmin).

This box may be improved.

The Konus-Wind time history and spectrum will be given in a forthcoming
GCN Circular.
