GRB 160625B

GRB 160625B is a gamma-ray burst (GRB) detected by NASA's Fermi Gamma-ray Space Telescope on 25 June 2016 and, three minutes later, by the Large Area Telescope.[1][2][3] This was followed by a bright prompt optical flash, during which variable linear polarization was measured[4] This is the first time that these observations are made when the GRB is still bright and active.[5] The source of the GRB was a possible black hole, within the Delphinus constellation,[6] about 9 billion light-years (light travel distance) away (a redshift of z = 1.406).[7]
