On 2017 June 8 at 02:01:16.49 UTC, a gravitational-wave (GW) signal from the merger of two stellar-mass blackholes was observed by the two Advanced Laser Interferometer Gravitational-Wave Observatory detectors with anetwork signal-to-noise ratio of 13. This system is the lightest black hole binary so far observed, with componentmasses of 12[superscript +7] [subscript -2]M[subscript ⊙] 7[superscript +2][subscript -2] (90% credible intervals). These lie in the range of measured black hole masses inlow-mass X-ray binaries, thus allowing us to compare black holes detected through GWs with electromagneticobservations. The source's luminosity distance is 340[superscript +140][subscript -140] corresponding to redshift 0.07[superscript +0.03][subscript - 0 03]. We verify thatthe signal waveform is consistent with the predictions of general relativity.
