Webter Gravitational-wave Observatory (LIGO) [2, 3] observed the ﬁrst gravitational-wave signal GW150914 from a bi-nary black hole merger [4]. In this letter we report the ob-servation of a second coincident signal GW151226, also from the coalescence of two black holes. An analysis of GW150914 and GW151226 as a population is described in [5].
