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

The long-duration, intense GRB 140308A has been observed by Konus-Wind, 
Suzaku (WAM), MESSENGER (GRNS), Swift (BAT), and Mars Odyssey (HEND), so 
far, at about 13766 s UT (03:49:26). 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:
   357.561 (23h 50m 15s) -33.348 (-33d 20' 54")
  Corners:
   357.844 (23h 51m 23s) -33.006 (-33d 00' 20")
   357.443 (23h 49m 46s) -33.802 (-33d 48' 06")
   357.271 (23h 49m 05s) -33.688 (-33d 41' 17")
   357.673 (23h 50m 42s) -32.891 (-32d 53' 28")
  ---------------------------------------------
The error box area is 549 sq. arcmin, and its maximum
dimension is 56 arcmin (the minimum one is 11 arcmin).
The Sun distance was 29.6 deg.

This box may be improved.
