Even with just two LIGO locations, they were able to give a very rough estimate of the source location during the livestream this morning. (It was somewhere kinda in the direction of the Magellanic clouds. Probably.) Once advanced VIRGO comes online (later this year?) we&#x27;ll have three, which will significantly improve directional accuracy for much of the sky. And when KAGRA turns on in Japan sometime around 2018, we&#x27;ll have four. During the livestream this morning, someone said that would lead to source locations accurate to within 5-10 degrees on the sky.
