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

The long-duration, intense GRB 140306A (Fitzpatrick and Stanbro, GCN 
Circ. 15935) was observed by Fermi (GBM), INTEGRAL (SPI-ACS), 
Konus-Wind, MESSENGER (GRNS), Suzaku (WAM), Swift (BAT), and Mars 
Odyssey (HEND) at about 12585 s UT (03:29:45). 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:
    27.943 (01h 51m 46s) +48.975 (+48d 58' 31")
  Corners:
    28.544 (01h 54m 11s) +48.781 (+48d 46' 52")
    28.271 (01h 53m 05s) +49.135 (+49d 08' 06")
    27.339 (01h 49m 21s) +49.163 (+49d 09' 47")
    27.617 (01h 50m 28s) +48.814 (+48d 48' 50")
  ---------------------------------------------
The error box area is 0.209 sq. deg, and its maximum
dimension is 53 arcmin (the minimum one is 20 arcmin).

This box may be improved.
