"SuperAGILE detected and localized a very bright gamma ray burst
on July 23rd 2008, at 13:22:19 UT. The event was approximately
13 degrees off-axis. The observed duration in the 20-60 keV
energy range is about 110 seconds, with a multi-peaked structure.
The burst position was reconstructed as (RA, Dec) (176.823 deg,
-60.262 deg), which is:

RA(J2000) = 11h 47m 17.42s
Dec(J2000) = -60d 15' 43.7"

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

The same event was also localized and announced by INTEGRAL/ISGRI 
(BACODINE trigger n. 5311, and Gotz et al., GCN 8002). 
The SuperAGILE position lies at 1.1 arcmin from the one 
reported in the INTEGRAL off-line analysis.

A SuperAGILE light curve of the event will shortly be posted on the AGILE 
Science Data Center website: http://agile.asdc.asi.it .

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