SuperAGILE detects a Gamma-Ray Burst associated to a Supernova

On December 11, 2011 at 22:17:33 UT the SuperAGILE hard X-ray monitor aboard the Italian AGILE satellite localized a Gamma-Ray Burst, GRB 111211A ( see GCN #12666 F. Lazzarotto et al.). The GRB 111211A is the first event detected by SuperAGILE associated with a Supernova. While an average number of about 200 – 300 GRBs are localised each year in the X-ray band, less than twenty firm associations with Supernovae are established up to now. The SuperAGILE GRB 111211A is a rare occurrence of a burst which appears to be accompanied by a Supernova explosion, and gives the opportunity to further investigate the GRB-Supernova connection.
