behalf of the AGILE MCAL team, report:

The long-duration GRB 130219A was observed by Fermi (GBM: trigger
382991754, Collazzi, GCN Circ. 14243Not found
 
 
), Konus-Wind, INTEGRAL (SPI-ACS), 
Suzaku (WAM), Swift (BAT), AGILE (MCAL), and MESSENGER (GRNS), at about 
66950 s UT (18:35:50). 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
    ---------------------------------------------
    Corners:
    311.189 (20h 44m 45s) +51.497 (+51d 29' 50")
    307.440 (20h 29m 46s) +48.611 (+48d 36' 41")
    296.804 (19h 47m 13s) +37.410 (+37d 24' 35")
    296.474 (19h 45m 54s) +37.565 (+37d 33' 53")
    ---------------------------------------------
The error box area is about 2.5  sq. deg, and its maximum dimension is 
17.4 deg (the minimum one is 9 arcmin).

This box may be improved.
