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

The long-duration, bright GRB 140329A (von Kienlin and Younes, GCN Circ. 
16042Not found
 
 
) has been observed by Fermi (GBM), Konus-Wind, INTEGRAL (SPI-ACS), 
MESSENGER (GRNS), and Mars Odyssey (HEND), so far, at about 25478 s UT 
(07:04:38).

We have triangulated it to a preliminary, 3 sigma error box whose 
coordinates are:
  ---------------------------------------------
   RA(2000), deg                 Dec(2000), deg
  ---------------------------------------------
  Center:
   146.246 (09h 44m 59s) -32.103 (-32d 06' 09")
  Corners:
   145.867 (09h 43m 28s) -31.797 (-31d 47' 49")
   145.948 (09h 43m 47s) -32.076 (-32d 04' 33")
   146.627 (09h 46m 31s) -32.404 (-32d 24' 13")
   146.544 (09h 46m 10s) -32.127 (-32d 07' 39")
  ---------------------------------------------
The error box area is 491 sq.arcmin, and its maximum dimension is 53 
arcmin (the minimum one is 12 arcmin).

The center of the GBM ground position (von Kienlin and Younes, GCN Circ. 
16042Not found
 
 
) is 5.6 deg from the center of the box.

This box can be improved.
