Аннотация:The observations of GRB over many years are discussed. The main key steps in GRB investigations are the following: the first simultaneous observations of GRB720117 (Cosmos-461 and Vela); the first bimodal distribution's discussion in 1981 by Mazets; the first GRB with optical afterglow investigations GRB970228 (BATSE); the first prompt observations of GRB by Akerlof (GRB990123, ROTSE-I response to BATSE alert) are demonstrated. The evolution of the coalescence rate of double neutron stars and neutron star-black hole binaries were first computed by Lipunov et al in 1995. We also discuss scenarios for long and short GRB. And there are some results of MASTER Global Robotic Net GRB observations.
