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

The extremely bright long 140219A has been observed by Fermi/GBM 
(trigger 414531995), INTEGRAL (SPI-ACS), Suzaku (WAM), Mars Odyssey 
(HEND) and MESSENGER (GRNS), so far, at about 71192 s UT (19:46:32).

We have triangulated it to a preliminary, 3 sigma error box whose 
coordinates are:
---------------------------------------------
idx  RA(2000),deg  Dec(2000),deg
---------------------------------------------
Center:
      156.44         7.46
Corners:
1    157.06	    10.06
2    156.56	    7.30
3    155.51	    4.70
4    156.31	    7.66
---------------------------------------------
The error box area is 0.644 sq. deg, and its maximum dimension is 5.57 
deg (the minimum one is 0.36 deg).

This box can be improved.
