"SuperAGILE detected and localized a gamma ray burst 
on February 29th, at 23:33:01 UT. The event was approximately 
13 degrees off-axis. The observed duration in the 20-60 keV
energy range is above 100 seconds, with time structure.
The burst was triggered and localized during on ground data processing.  
The burst position was reconstructed as (RA, Dec) (199.221 deg, 
-64.878 deg), which is:

RA(J2000) = 13h 16m 53.13s
Dec(J2000) = -64d 52' 40.8"

with an uncertainty of 3' radius. The given uncertainty accounts 
for both the statistical and systematic errors. 

An analysis of the AGILE Gamma Ray Imager (GRID) data is in progress."
