on behalf of the AGILE Team, report:

"SuperAGILE detected a gamma ray burst on 28 August 2008, at 03:14:45 UT. 
The event had a duration of about 25 s in the 20-60 keV energy range, 
with a single-peak structure.
The burst position was reconstructed 
as (RA, Dec) (199.626 deg, -65.930 deg), which is:

RA(J2000)  = 13h 18m 30.32s
Dec(J2000) = -65d 55' 48.2"

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."
