On 2017 June 8 at 02:01:16.49 UTC, a gravitational-wave (GW) signal from the merger of two stellar-mass black holes was observed by the two Advanced Laser Interferometer Gravitational-Wave Observatory detectors with a network signal-to-noise ratio of 13. This system is the lightest black hole binary so far observed, with component masses of {12}<SUB>-2</SUB><SUP>+7</SUP> {M}<SUB>☉ </SUB> and {7}<SUB>-2</SUB><SUP>+2</SUP> {M}<SUB>☉ </SUB> (90% credible intervals). These lie in the range of measured black hole masses in low-mass X-ray binaries, thus allowing us to compare black holes detected through GWs with electromagnetic observations. The source’s luminosity distance is {340}<SUB>-140</SUB><SUP>+140</SUP> {Mpc}, corresponding to redshift {0.07}<SUB>-0.03</SUB><SUP>+0.03</SUP>. We verify that the signal waveform is consistent with the predictions of general relativity.
