From Wikipedia, the free encyclopedia
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.

[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.
