This source was shown to contain a 5-15$M_{\\odot}$ black hole and a massive 18-23$M_{\\odot}$ B9Ia companion on a 64 day orbit. For low black hole mass (5-10$M_{\\odot}$) and high companion mass $\\gtrsim 20 M_{\\odot}$ the binary is predicted to initiate a common envelope evolution in near future and significantly decrease the orbital separation (6 hr orbit). This leads to a high probability ($\\sim70\\%$) of the system surviving a supernova explosion that will form a neutron star out of the companion.
