GRB 160625B was a bright 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 was the first time that these observations were made when the GRB was 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] It had a fluence of 5.7×10⁻⁴ erg cm⁻², and energy of 5 × 10⁵⁴ erg.^[8]
