"SuperAGILE detected and localized a gamma ray burst
on June 25th 2008, at 12:28:31 UT. The event was approximately
22 degrees off-axis. The observed duration in the 20-60 keV
energy range is about 80 seconds, with a single peak structure.
The burst was triggered and localized on ground.
The burst position was reconstructed as (RA, Dec) (298.4423 deg,
56.2653 deg), which is:

RA(J2000) = 19h 53m 46.14s
Dec(J2000) = 56d 15' 55.1"

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."
