GRB

The knowledge about GRBs (Gamma Ray Bursts) is growing.

I try to detect optical counterparts of GRBs announced by the satellites HETE, SWIFT and INTEGRAL. I collabore with the High Energy Network of AAVSO (American Association of Variable Star Observers). Since 2002, 13 optical counterparts were detected from Gnosca. No more observations were made after 2011.
