"SuperAGILE detected a gamma ray burst on 12 August 2011, at 00:20:08 UT.
The event had a duration of about 30 s in the 20-60 keV energy range,
with a multi peak structure. Assuming a crab-like energy spectrum, the  
peak flux on 1-s timescale was 8.91E-08 erg/cm2/s.
The burst position was reconstructed as (RA, Dec)
(358.409, 72.206) deg, which is:

RA(J2000)  = 23h 53m 38.15s
Dec(J2000) = 72d 12' 23.32"

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."
