Radio observations of black hole MAXI J1820+070’s 2018 outburst captured an isolated radio flare that the authors connect with the launch of bipolar relativistic ejecta. Following the oncoming ejecta for more than half a year reveals that black hole jet energetics have been systematically underestimated.
