V. Connaughton, M. S. Briggs, C. Meegan, and V. Pelassa, on behalf of the Fermi
GBM team, report:

GRB 141118A has been observed by Fermi GBM, Konus-Wind, RHESSI, Swift
(outside the coded field of view), Odyssey (HEND), and MESSENGER
(GRNS), so far, at 58550 s (16:15:50 UT) so far.  We have triangulated
it to a preliminary, 3 sigma error box whose area is 2890 sq. arcmin.
and whose coordinates are:

              RA(2000)                      DEC(2000)
CENTER:  156.874 o =10 h 27 m 30 s     19.079 o= 19 o 04 ' 45 "
CORNERS: 157.620 o =10 h 30 m 29 s     21.134 o= 21 o 08 ' 01 "
         156.676 o =10 h 26 m 42 s     19.104 o= 19 o 06 ' 15 "
         157.071 o =10 h 28 m 17 s     19.054 o= 19 o 03 ' 13 "
         155.644 o =10 h 22 m 35 s     15.768 o= 15 o 46 ' 06 "

This error box may be improved.  A map has been posted at  Details of this burst will be
given in a forthcoming GCN Circular.
