Verrecchia (ASDC) and L. Salotti (ASI), on behalf of the AGILE Team, 
report:

"SuperAGILE detected a gamma ray burst on 26 January 2009, at 02:01:15 UT.
The event had a duration of about 60 s in the 20-60 keV energy range,
with a structure composed of two separated main peaks. Assuming a 
Crab-like energy spectrum, the peak flux on 1-s timescale was 1.5E-07 
erg/cm2/s.
The burst position was reconstructed  as (RA, Dec)
(3.848 deg, 81.365 deg), which is:

RA(J2000)  = 00h 15m 23.50s
Dec(J2000) = 81d 21' 53.78"

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."
