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

The long-duration, very intense GRB 150330A has been detected by Fermi 
(GBM: Stanbro, GCN Circ 17658), Konus-Wind, MESSENGER (GRNS), INTEGRAL 
(SPI-ACS), Swift (BAT) and AGILE (MCAL), so far, at about 71541 s UT 
(19:52:21). 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:
   331.028 (22h 04m 07s) +52.297 (+52d 17' 48")
  Corners:
   327.825 (21h 51m 18s) +50.740 (+50d 44' 25")
   328.325 (21h 53m 18s) +51.170 (+51d 10' 12")
   334.589 (22h 18m 21s) +53.730 (+53d 43' 47")
   333.942 (22h 15m 46s) +53.336 (+53d 20' 10")
  ---------------------------------------------
The error box area is 2388 sq. arcmin, and its maximum
dimension is 5.1 deg (the minimum one is 8.6 arcmin).
The Sun distance was 57 deg.

This box may be improved.

The Konus-Wind time history and spectrum will be given in a forthcoming 
GCN Circular.
