GW170608 was a gravitational wave event that was recorded on 8 June 2017 at 2:01:16.49 UTC by Advanced LIGO. It originated from the merger of two black holes with masses of ${\displaystyle 12_{-2}^{+7}\,M_{\odot }}$ and ${\displaystyle 7_{-2}^{+2}\,M_{\odot }}$.^[1][2] The resulting black hole had a mass around 18 solar masses. About one solar mass was converted to energy in the form of gravitational waves.^[3]
