G. Di Cocco, F. Fuschino, M. Galli, C. Labanti, and M. Marisaldi, on 
behalf of the AGILE MCAL team, report:

The long-duration GRB 120919A (Fermi/GBM detection: Rau, GCN Circ. 
13785) was observed by Konus-Wind, MESSENGER (GRNS), Mars Odyssey 
(HEND), INTEGRAL (SPI-ACS), and AGILE (MCAL) at about 26682 s UT (07:24:42).

We have triangulated the burst to a preliminary, 3 sigma error box whose
coordinates are:
   ---------------------------------------------
     RA(2000), deg                 Dec(2000), deg
    ---------------------------------------------
    Center:
     214.768 (14h 19m 04s) -45.564 (-45d 33' 52")
    Corners:
     215.108 (14h 20m 26s) -45.474 (-45d 28' 26")
     214.693 (14h 18m 46s) -45.722 (-45d 43' 19")
     214.428 (14h 17m 43s) -45.653 (-45d 39' 09")
     214.843 (14h 19m 22s) -45.407 (-45d 24' 24")
    ---------------------------------------------
The error box area is 236  sq. arcmin, and its maximum
dimension is 31 arcmin (the minimum one is 12 arcmin).

This box can be improved.

The center of the GBM ground position given in
GCN Circ. 13785 is 1.2 deg from the center of this box.
