report:

"SuperAGILE detected and localized a gamma ray burst 
on May 7th, at 07:45:00 UT. The event was detected during the
passage of the AGILE spacecraft through the South Atlantic 
Anomaly and this caused the non-detection by the automatic
burst search procedures, and the delayed identification thereof.
The observed duration in the 20-60 keV energy range is about 40 seconds, 
with a multi-peaked structure.
The burst position was reconstructed as (RA, Dec) (233.721 deg, 
56.424 deg), which is:

RA(J2000) = 15h 34m 53.11s
Dec(J2000) = 56d 25' 27.3"

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

This position lies approximately 100 arcsec from the galaxy NGC 5969.

The telemetry of the AGILE Gamma Ray Imager (GRID) is disabled 
during the passage through the South Atlantic Anomaly, thus no
GRID data are available for this GRB."
