GRB 150101B - gamma-ray burst , discovered January 1, 2015 at 15:23 UT on the BAT telescope aboard the Swift spacecraft and at 15:23:35 UT on the telescope of the Fermi observatory. [1] According to estimates, the gamma-ray burst was located at a distance of 0.52 G pc from the Sun near the active galaxy 2MASX J12320498-1056010 [4] in the constellation Virgo. [1] [3] [2] Observations of GRB 150101B showed similar characteristics with event GW170817 , which suggested the fusion of neutron stars . [3] [5] [6] [7]

Observations
In October 2018, astronomers reported that the gamma-ray burst GRB 150101B could be similar to the burst GW170817 , whose gravitational waves were detected in 2017, at a distance of about 130 million light-years; GW170817 is associated with the fusion of two neutron stars . The similarity between the two events observed in the gamma radiation, the optical and x-ray ranges, as well as the nature of the associated galaxies may indicate the nature of the burst as a result of the fusion of neutron stars, or the burst may be the result of an unknown class of transient kilon stars . In the latter case, the phenomena of the kilon are more diverse than is commonly believed. [1] [3] [5] [6] [7] [8]
