The short-duration, hard spectrum GRB 140906� (Golenetskii et al., GCN 
16801) was also observed by RHESSI and Odyssey. Using Odyssey data 
reduces the size of the previous error box by about a factor of 6:
   RA(2000), deg                 Dec(2000), deg
   314.961 (20h 59m 51s)  +1.939 ( +1d 56' 21")
   315.057 (21h 00m 14s)  +1.949 ( +1d 56' 57")
   314.869 (20h 59m 29s)  +2.439 ( +2d 26' 22")
   314.866 (20h 59m 28s)  +1.929 ( +1d 55' 45")
   315.057 (21h 00m 14s)  +1.428 ( +1d 25' 41")
The error box area is 355 sq. arcmin, and its maximum
dimension is 1.0 deg (the minimum one is 11 arcmin).

Some further improvement in this error box is possible.
