Another LIGO Gravitational Wave Event

[1711.05578] GW170608: Observation of a 19-solar-mass Binary Black Hole Coalescence

Two black holes with masses of 12 and 7 solar masses were involved. This the lightest BH binary merger so far detected by LIGO.

Just wait until LIGO can routinely detect gravitational waves in 0.2 to 1.0 solar mass range. Socks will be blown off!
