GW170104 was a gravitational wave signal detected by the LIGO observatory on 4 January 2017. On 1 June 2017, the LIGO and Virgo collaborations announced that they had reliably verified the signal, making it the third such signal announced, after GW150914 and GW151226, and fourth overall.

==Event detection== The signal was detected by LIGO at 10:11:58.6 UTC, with the Hanford detector picking it up 3 milliseconds before the Livingston detector. Automated analyses did not initially identify this event as information about the state of the Hanford detector was not being correctly recorded. The event was found by a researcher at the Max Planck Institute for Gravitational Physics by visual inspection of triggers from the Livingston detector. The gravitational wave frequency at peak GW strain was 160 to 199 Hz.
