First gamma-ray burst observations with the sigma telescope
Abstract
The anticoincidence shield of the SIGMA telescope is being used as a Gamma-Ray Burst detector. Six months after the launch of the GRANAT spacecraft, a dozen bursts have been detected whose main characteristics are presented here; in particular, the first observations reveal a unusually high rate of short, hard bursts.
